EICO RESISTANCE-CAPACITANCE-COMPARATOR BRIDGE
EICO CAPACITOR TESTER / CHECKER
EICO 950B
#55251-W (FACTORY WIRED EDITION)
WITH CONTINUOUSLY VARIABLE VOLTAGE OUTPUT (HANDY FOR 'RE-FORMING' CAPACITORS)
Circa late 1950's through mid 1970's
for sale

- We completely went through this spending an inordinate amount of time testing parts, replacing parts, modifying wiring and testing along the way and following it's restoration
- All old foil caps replaced with Orange / Brown drops of at least Voltage in kind, but often higher values
- All 10% (Silver) 'Carbon' resistors replaced with 'hand picked' units that went well beyond 5-10% accuracy (a couple of the originals were way out of spec)
- The 8uF / 525Volt cap replace with a VERY difficult to find and expensive 8.2uF / 600 Volt unit.
- Tubes tested and recorded
- Even though this was a 'Factory Wired / Assembled' Eico 950B, we still went through and inspected all joints and re-soldered quite a few
- 3-Prong, Grounded AC Power cord installed
- Externally located fuse installed (0.3A)
- 'Death Cap' REMOVED (you can research that process on many 'vintage tube' units, but again, installing the 3-Prong cord also addressed any potential issues related to the 'Death Cap')
- Cleaned inside and out ) steel cabinet could use a 're-fin' still
Unit tests well. One thing Eico 950 owners know is that it's rare that the 'Voltage Test' will go up to 500* Volts. Most go up to about 450 V. This one will peak at 490 Volts. The 'Scale' on the 'Voltage Knob' is not generally complimentary on any of these types of testers. We set the knob for accuracy at 100 Volts, but we suggest connecting an external Volt meter to the outputs to monitor the actual Voltage being produced. There is a resistor ("R8" we've read) that we understand can be changed to a lower value that will increase the output voltage, but that's not our place to modify from original designs (other than for reasons of 'safety').
This scale indexes on this one produces the following Voltages; 10=25VDC, 50=60V, 100=100V, 150=146V, 200=190V, 250=236V, 300=276V, 350=329V, 400=384V, 450=439V & 500*=490V (you can 're-center' the knob for what ever figure you want to be the most accurate with it's 'set-screw').

EICO 950B Capacitor Checker / Tester. These are incredibly versatile instruments. They can compare / test resistor and capacitors as well as chokes and transformers. Since they can actually 'test at voltage' for leakage, they are so much more 'usable' than most any 'modern', digital meter. Those don't test at the voltages these are capable of, thus aren't really much good for testing for 'leakage'. These are since they can actually output a 1kHz tone at 500* Volts. So here's the deal. We use these here in the shop, along with a few others. Depends on what mood the tech is in. Really all do pretty much the same thing. This one is for sale, but is also being use (real world tested) currently.

EICO RESISTANCE-CAPACITANCE-COMPARATOR BRIDGE Features;

- Capacitance measurement of Mica, Paper, Electrolytic, and Ceramic Capacitors
- Measures Inductance, Capacitance, Resistance. - Impedance Comparator for checking and comparing electrical components and matching coils etc.
- Comparator to determine unknown component values
- Capacity ranges from 10mmfd (pico-Farrard), to 5000 mfd / uF in 4 overlapping ranges.
- Ohm meter for resistive components
- Resistance ranges from 0.5 Ohm to 500 megOhms in 4 overlapping ranges.
- Leakage test for caps / condensers up to 500* Volts (one of the nicest aspects of this unit is that the 'voltage function' on the Eico, over say a 'Heathkit' is that the voltage adjustment is 'continuously variable' instead of in 'pre-determined steps'. One of our testers goes in 'steps' from 25V to 50V to 100Volts and is frustrating {and potentially damaging / dangerous} to try and test caps that are often rated at 35 Volts and 75 Volts. Being 'continuously variable' is also WAY better for 'Re-forming' capacitors.)
- Checks intermittent capacitors / condensers 'under load'
- 117VAC / 18 W / .15A

Great testers / checkers, but unless one has been COMPLETELY re-capped / restored, they're just cool looking 'boat anchors'. A piece of test gear is only as good as "how close it get's to 100% accuracy". These are 60+ year old units, and while they can be brought back to their former glory (and then some), unless it's been done by someone qualified and correctly, then again, they're just 'boat anchors' (and I'm not talking about just powering it up on a vari-ac and making sure not smoke comes out). To be usable ALL the electrolytic and foil capacitors need to be changed with fresh and tested caps (including difficult to find 500-600 Volt electrolytics). Carbon resistors are tested. Since many of these were sold as 'kits', one of the most important process we do is to inspect and most likely correct, any wiring errors (meaning the person that assembled the kit, connected wires and parts to the wrong place...and we usually find 2-4 on most units). We then test / replace all tubes. Once all of that is done, and ONLY THEN should the unit be powered up, and that should only be done on a vari-ac with an ammeter. Following the 'parts restoration' calibration and testing can be undertaken. 
All of the above work represents many hours of tech time (typically 7-12 hours {this one took about 12+ hours}) and parts.
This unit has dark, red 'chicken head' knobs. I don't know if they're original. They look like the same knobs used on some Jackson tube testers.

ORIGINAL HEATHKIT SOLDERING IRON / STATION
3 TEMPERATURE HEATHKIT GH-17A
Circa 1966-1982
for sale

This is a great soldering iron / station, and frankly VERY usable. 3 temperatures that are simply controlled by selecting different secondary taps on the transformer (no rheostats or electronics to go bad). Utilizes the very durable 6V, 25W, GE, 6A203 'midget' iron as a basis. This is the "A" version which means that it has a 'grounded plug' (3-prong) and the ground pin is still intact. Both Iron and power cables supple, crack / split free and not brittle.

From the original Heathkit catalog, “Heathkit Soldering Iron Kit . . .The Best For Kit -Building!
LIGHTWEIGHT . . . COMPACT . . . EASY TO HANDLE! Ideal for kit -building or any "tight" soldering work. The 6 volt, 25 -watt General Electric midget-type industrial soldering iron features a long-life, iron -clad tip that won't corrode or require frequent "tinning." Connects to high or low voltage lines to effectively provide selection of 3 heat ranges ...handles any soldering job from "low- heat" circuit board to "hot" heavy -duty chassis work! Excellent heat recovery time! Includes transformer- operated power supply and protective metal cage.”

Unit tests great. A great and seldom known feature about this iron is that when the iron is in it's rest (holder) it can be pushed 'proud' of the rear of the housing thus allowing 'hands free' soldering (well not really "hands free", but you don't need a 'third' hand to hold the iron).
Iron has 6', flexible, kink-free cord. Wood handle stays cool. Tips 'tins' easily and well.
Pilot light lights brighter as temp is increased.

Here's a link to some great info on it;

https://www.w6ze.org/Heathkit/Heathkit_005_GH17.pdf

Original blue-grey, 'crinkle' finish in great shape. All silk-screening intact. Original "Heathkit model" sticker intact. All four original anti-skit, rubber feet intact. All original chassis screws.
Has GE 6A203 'Midget', Wood-handle iron.

MANHATTAN PROJECT ELECTRONIC TEST EQUIPMENT
FROM THE SECRET LOS ALAMOS LABORATORIES

The following electronic laboratory test gear is purported to have come from Los Alamos National Laboratory (LANL) in Los Alamos, New Mexico.

In the late 1930's, the US Department of Defense was looking for a remote and secret location for the classified 'Manhattan Project'. This was the Allied project (led by the United States with participation from the United Kingdom and Canada), during World War II, to develop the first nuclear weapons. The US government used its power of eminent domain in 1942 to take over the Los Alamos, 'Ranch School' and all homesteads of the town.
All information about the town of Los Alamos was highly classified until the bombing of Hiroshima, Japan.
Known at various times as 'Project Y', 'Los Alamos Laboratory', and 'Los Alamos Scientific Laboratory' it is one of two laboratories in the US where classified work towards the design of nuclear weapons was undertaken.
From 1942 to 1946, Los Alamos was responsible for the development of the 'H-bomb' and many other nuclear weapons.
Is it safe to assume that some of this test equipment below was used in those developments?.....

Frequency range 1 Hz to 1 MHz. Generates Sine, Square and Saw-tooth waveforms. Adjustable D.C. offset. Looks and works great. All functions seem to check fine. May need a slight calibration, but was very close to our bench unit and with our Frequency Counter. The wave forms also looked great on our scope. Utilizes standard "Banana" style probes / leads (not included). Sorry no manual with it. Detachable AC cord has been modified / permanently attached. Includes our standard 30 day limited warranty for test gear.
(we may decide to keep this for shop use as it features adjustable 'DC Offset', but until that time, it's available for sale)

PROFESSIONAL "MASTER APPLIANCE" HEAT GUN
MASTER APPLIANCE HG-501A
USA MADE!!!

Variable heat (via adjustable vent) from 500 to 750 degrees F.
Works great and is in excellent shape. Does way more than the heat gun we have at our electronics shop, but is ‘overkill’ for what we use one for. One thing this does that ours doesn’t do, is it has a ‘cool’ down setting so you don’t have to wait too long to put it away.
Very heavy AC cord is in great condition with no cracks or splits. Ground prong still intact.
Stand allows it to be used ‘free hand’ in many positions (great for shrink wrap / tube).
Runs great! Motor bearings quite with no squeal or rattle. Brushes are easily replaceable from the outside and still in good condition. Heating element is replaceable as well and also works great now.
Gets HOT FAST!!!
Don’t need to sell it, just don’t often need two here at the shop and in a couple years will be downsizing anyway so it’s currently up for sale.
Includes our standard 30 day warranty for tech gear.
These get great Amazon ratings.

NLA. SORRY.

*Again, Vari-AC's can have many uses. Varying the speed of a motor, bringing voltage up slowly on gear for trouble-shooting, getting "brown AC" to guitar tube amps, and controlling the brightness of a lamp are only a few. It is a tool. Some "tools" are designed for many "known uses", but in the hands of qualified personnel, can be used for other "non-designed" uses. Improperly used, this "tool" can be dangerous, even fatal both to the operator and to the equipment. No warranties are expressed or implied. If you do not understand the use of a Vari-AC on a film projector, DO NOT PURCHASE, OR USE ONE!

AMERITEC
AM5XT
VOICE/DATA TRANSMISSION TEST SET
SOLD 3/9/07

I know a little about a lot of different stuff and a lot about a few things, but virtually nothing about Transmission Test Sets. We have had a couple in the past that have sold, but that's all I know. Unit fires up and does respond to it's switches. The last one we had could do a "self-test", but I don't know how to engage a test with this unit. According to some other info on the web:

"The Ameritec AM5eXT-200 Wideband Transmission Test Set is specifically engineered for peak performance for use in the field and in the lab. This easy-to-use unit offers a full range of transmission impairment measurements and a highly versatile signal generator in a single, compact, portable instrument. Approximately the size of a telephone directory, this test instrument fits conveniently on a bench top for use as a laboratory unit. It can also be rack mounted."
"Portable wideband transmission impairment set with sweep function that can be programmed to automatically perform tests across the 20 kH to 200 kHz bandwidth, while simultaneously measuring level and frequency across the same bandwidth."

"100% digital control of all measure, filter, send, and termination functions"
"Front panel with easy-to-locate and easy-to-read areas for each of the major instrument functions."
"Together with the optional internal rechargeable battery pack and soft carrying case, the AM5eXT-200 can be used as a field tester with a battery life of up to six hours of uninterrupted use."
"Performs qualification tests on circuits carrying voice band, high quality audio, and basic rate ISDN and HDSL or other services using up to 200 kHz bandwidth."
"Simultaneously sends signal and measure received signals."
"Provides individual selection of "send and receive terminations" and "on hook/off hook DC hold" circuits."
Testing capabilities include dBm level or dB loss, frequency, frequency response (attenuation distortion), noise (wideband or with filters), noise with tone (wideband or with filters), signal-to-noise ratio (wideband or with filters), noise to ground (wideband or with filters), impulse noise (wideband or with filters), phase jitter, amplitude jitter, micro interruptions, group delay, inter-modulation distortion (4-tone/2-tone), 2- and 4-wire return loss, and transients (including phase and gain hits as well as impulse noise with tone and interruptions)."
"Sophisticated test scripts can be obtained by simply drawing the test sequence. Call scripts are easily developed by dragging, dropping, and interconnecting icons to create a graphical call flow diagram."


 Sorry no manual with it. Measures 8" wide 12" deep 4" tall (with stand folded in) and weighs 7 lbs unpacked. AC cord included.

SOLID STATE
SOLD 
 Our favorite tester. We have one we have used for years and keep calibrated. Since it's solid state you don't have to worry that it's internal tubes have drifted. (Will not test early 4-pin or Acorn style tubes, but will test all popular and modern (post mid 40's) tubes). Features include:
- "Jet Check" testing section for very quick testing of select tubes
- Programmed Testing
- Dynamic Testing
- Tests High Voltage Regulators with proper current (dynamic test injects a signal voltage into the Grid and another much higher voltage is applied to the plate at the same time)
- Shorts Test (leakage paths up to 1 megohm and leakage as low as .5 microampere. 
- Grid Emission Tests (tests up to 100 megohms)
- Life Test (tests tubes remaining reserve or life expectancy)
- Dual Section testing (Each section of a multi-section tube can be tested separately)
- Voltage Regulated
- Overload Protection ( Manual circuit breaker protects if an unusually high load is inserted i.e a shorted tube.)
Very accurate tester. We have completely gone though it doing all calibrations as follows: 1) Signal Level set 2) Bias Voltage set 3) Meter Bridge Balance set 4) Shorts Sensitivity set 5) and finally Grid Emission Sensitivity set. Meter tests and works great! Exactly as our shop B&K 747B. Includes both the version II Tube chart (lists over 2500 tubes) and a copy of the manual / calibration guide. All 30 on board tube sockets in perfect condition. All controls function perfectly. Meter looks new! Even has built-in pin straightening for 7 pin miniature, 9 pin miniature, Noval / magnoval & Decal / Compactron tubes. Tester is built into a blow-molded heavy duty plastic case. Measures 21" wide x 13" deep. Includes our standard 30 day limited warranty for test gear.

Circa late 1950's / early 1960's

SOLD AS 'RESTORED' 4/21/18
SHIPPING TO OKLAHOMA
EICO 950A Capacitor Checker / Tester. These are incredibly versatile instruments. They can compare / test resistor and capacitors as well as chokes and transformers. Since they can actually 'test at voltage' for leakage, they are so much more 'usable' than most any 'modern', digital meter. Those don't test at the voltages these are capable of, thus aren't really much good for testing for 'leakage'. These are since they can actually output a 1kHz tone at 500 volts. So here's the deal. We use these here in the shop, along with the Heathkit IT-11 / IT-28 and C3. Depends on what mood the tech is in. Really all do pretty much the same thing.

EICO RESISTANCE-CAPACITANCE-COMPARATOR BRIDGE FEATURES;

- Capacitance measurement of Mica, Paper, Electrolytic, and Ceramic Capacitors

However, unless one has been COMPLETELY re-capped / restored, they're just pretty 'boat anchors'. A piece of test gear is only as good as "how close it get's to 100% accuracy". These are 45+ year old units, and while they can be brought back to their former glory (and then some), unless it's been done by someone qualified and correctly, then again, they're just 'boat anchors' (and I'm not talking about just powering it up on a vari-ac and making sure not smoke comes out). To be usable ALL the electrolytic and foil capacitors need to be changed with fresh and tested caps (including difficult to find 500-600 Volt electrolytics). Carbon resistors are tested. Since many of these were sold as 'kits', one of the most important process we do is to inspect and most likely correct, any wiring errors (meaning the person that assembled the kit, connected wires and parts to the wrong place...and we usually find 2-4 on most units). We then test / replace all tubes. Once all of that is done, and ONLY THEN should the unit be powered up, and that should only be done on a vari-ac with an ammeter. Following the 'parts restoration' calibration and testing can be undertaken. Once that's completed and signed off on, then the unit will have final detailing done. Since all of the above work represents many hours of tech time (typically 7-10 hours) and parts, it scares off most initial / newbie buyers of these, so we are offering it two ways. 'As-Found' or 'Completely Refurbished'.

With the exception of the case (see photo collage) this one is in great shape. We have given it a "lite" going over, checking internal caps, testing internal tubes, cleaning contacts, "tweaking" tube chart for easier rolling and given it a good cleaning overall. We then spot checked a few different tubes with results consistent with our calibrated "shop" B&K 747B (747B - easy to use, but no where near the level of gear the 752 Hickok is).

VARIAC

Accepts 110 or 220 AC volts input. 9 amp capacity. 10-140 volts output with 110 volts input. Great for general bench work, reforming and breaking in filter caps, troubleshooting tube amps by lowering or increasing their voltage, or dimming lighting. Also could be used to run a tube amp "brown" if you so desire. Very heavy duty, older USA made unit. Much more durable than most of the import units. Very well ventilated. Can be mounted to a panel from the inside, or left free-standing. Output bolts are 1/4". Shaft should have knob installed. It's diameter is 3/4", and it protrudes 1 1/4" from the front. Unit diameter is 8" at it's widest point, and 7" tall not counting the shaft.  The variac weighs 26 lbs.


Warning:
Due to high potential AC current and voltage, Vari-AC's are very dangerous for the untrained user. Only for use by qualified technicians!

TRANSMISSION TEST SET
SOLD 3/9/07

I know a little about a lot of different stuff and a lot about a few things, but virtually nothing about Transmission Test Sets. We have had a couple in the past that have sold, but that's all I know. Unit fires up and does respond to it's switches. The last one we had could do a "self-test", but I don't know how to engage a test with this unit. According to some other info on the web it's used for testing digital radio, fiber-optic and T-carrier systems including multi-plexers, switches and lines. Has GPIB and RS 232 outputs.? Sorry no manual with it. Measures 13.5" wide x 17.5" deep x 7" tall (with stand folded in) and weighs 20 lbs unpacked. AC cord included.

TEAC TASCAM
TO-122A TEST TONE OSCILLATOR
for sale
Also great for injecting signal into amps and mixing board!

I used these Teac TO-122A Test Tone generators for years in the field as a Tascam dealer. I always had one in my tool box for testing Pro-Audio sound systems in clubs and churches. I used them to detect signal paths and look for anomalies in room acoustics at different frequencies. They're also great for setting levels on input gains and for leveling power meters. They have many other uses as well. Small package runs off a standard 9-volt battery. Fixed 1/4" out. Frequencies are selectable 40Hz, 400Hz, 1kHz, 4kHz, 10kHz and 15kHz. Levels are selectable between -10 or -40dB. Unit works perfectly and looks great. LED to show power on. Easy 2-screw battery change if you accidentally leave it on or just need to change the battery. Unit is small enough to fit in your tool box measuring only 3 1/8" wide x 2.5" deep x 1.5 tall. These are no longer available from Teac new.

ANALOG 'VOM'
Circa 1963
SOLD 11/22/11
 Unit in 'Like New', unused or virtually unused condition. True 'Museum' quality find. We see these and Simpson 260's all the time, but almost always pass them up as the meter needle will have sluggish to very sluggish movement (and are not very serviceable if that is the case). This is one of about 30 we have come across that has no 'sluggishness' to the needle movement (good question to ask when you're looking at a 'cheaper' one on an online auction).
No cracks in window or rust. All original knobs.
Meter & Scale: 50uA taut-band movement. 4.5" mirrored scale. Temperature compensation. All range polarity-reversing switch. Slide switch for range doubling. 
Overload Protection : Meter movement is semi-conductor (diode) network protected. 12AMP/250V fuse protects the 12 Amp range. 1.25 Amp/250 Volt fuse protects other ranges.
Features:

-  Single range switch to help reduce chance of operator error
-  Diode overload protection and 2 fuse arrangement
-  Mirrored scale to reduce parallax error 
-  Decibel function for audio work
-  All ranges are fuse protected 
-  'Thermoset' plastic case
-  Ranges and Functions
-  Glass meter window for added chemical resistance
-  Two input jacks to help minimize error
-  AC Voltage frequency response to 40KHz typical
-  Resistance measurement of 30V / 100M on Rx100K range for testing insulation

Specifications / Specs:
DC Voltage Ranges: 0-0.25 (10,000 Ohms/Volt, 0-2.5, 10, 50, 250, 1000 (20,000 Ohms/Volt)  Accuracy: ± 1.5% of Full Scale

Comes with original, un-used (still wrapped) probes. Original leather handle and case in excellent, almost new condition. Includes a copy of the owners / users manual. Attention, you will need special batteries to utilize this meter and they are not included, nor do we have access to them. We tested it with our bench power supplies. The required batteries are: B1 = 1.5v 'Burgess' No. 2 or equivalent (you can use a standard 'D' cell for this one) and B2= 30V Burgess, U20E or Eveready 413 for the '100,000 Ohm' range.
Includes our standard 30 day warranty for test gear (excluding blowing it up by injecting voltage when in Ohms position or similar). Measures 7.75" tall x 5.5" wide and 3.5" deep and weighs ~5 lbs.
