CONSONANCE STEREO RECEIVER / 8-TRACK / CASSETTE TAPE DECK COMBO / COMPACT STEREO UNIT ("CASSIEVER", except also w/ 8-Track).
This was a unit we acquired missing some parts, including the case and back panel, which likely had the model number listed, so we don't know what model it is.
PARTING OUT
 

 

Did you know?
MCS was marketed in the US, by JCPenney's in the 1970's and '80's and has generally proved to be solidly designed and built gear in the long run (not so much gear past early 1980's). Most MCS (Modular Component Systems) equipment was built by either Matsushita (parent company of Panasonic (founded 1918) and Technics (introduced 1965) or NEC (established 1898-99, originally known as Nippon Electric Company). Both VERY well respected, electronics industry giants. Most of the MCS stereo receivers and amplifiers prove to be fine performers once 'Certified' by a qualified technician. There are a few 'exceptions' and when we encounter one, they don't even make it to the bench, but then, most brands, including Pioneer, Marantz, Sansui, Kenwood, Sony & Yamaha made a handful of 'exceptionally cheaply designed and built' models that we won't bother to refurbish / restore. When I sold either Technics or Panasonic gear new, I knew there was a VERY low chance of that unit coming back with an issue, over many of the other brands I might have had at my disposal. Needless to say, I am a fan of most gear built by Technics / Panasonic and have seen enough of it to know that if I had to place a 'blind-bet' on an 'as-found' unit either being in 'functioning condition' or being close to it, gear built by Matsushita (NEC as well) will be a 'safe bet'.

SHIPPING TO ROBERT IN OKLAHOMA
  ü  Our technician has completely gone through and 'Certified' this unit.

ü  We have completely gone through this unit cleaning everything including all switches, controls and contacts. Extensive cleaning of unit internally.

ü Internal fuses checked for continuity and correct values. No issues found, fortunately. We don't like seeing incorrect fuses having been installed in a unit as that could mean it had prior issues, or if a fuse value was 'increased' it could have allowed too much current through an 'ailing' circuit causing un-due / un-necessary damage.

ü Controls were 'flooded' w/ 'De-OxId' and are quiet

ü Frozen / sluggish tuning meters re-adjusted for correct operation

ü Missing control switch cap sourced and modified for correct function

ü Tuner string checked for any fraying then re-tensioned to increase traction & relieve flywheel binding and re-centered pointer to correct dial position.

ü  We aligned the tuner front-end for optimum AM & FM performance as older internal tuner components have always drifted on vintage gear over the years.

ü  We also aligned the tuner dial with the tuning capacitor via the 'capacitance centering' screw on the tuning cap.

ü All dial, indicator & meter lamps 'proactively' replaced w/ #658 x4

ü We also checked the heat sink compound which should be good for another 30 years.

ü All inputs tested and both side produces clean and even sine waves into 'brick-wall' 8 & 4 Ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine.
Total restoration time investment 11 hours.

ü Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours into a 4 Ohm load.

On our test bench, this particular 3235, #...2761 amplifiers each produced 20 Volts per channel for 50 Watts per channel @ 8 Ω via discrete output & 17 Volts per channel for 72 Watts per channel @ 8Ω via discrete, TO3 Metal Cased outputs (2 each 2N3055 and MJ2955)
AC Idle current at 300mA, DC offset output adjusted to <15 mVDC either channel. Floor noise measured at >-60dBm w/ AUX shorted.)

Impressive & huge MCS 3235 (Modular Component Systems) Silver-face receiver. LOADED with features. This is the first one of this model we've had in over two decades. MCS units were usually built by either Matsushita (Technics / Panasonic) or NEC, both OEM 'giants' in the electronics industry. Only remaining 'issues' are the 'balance control' 'feels' like it 'drags'. It's been flooded with cleaner numerous times. Sonically it's fine with no static. Just 'feels' bad (most folks are not going to do much with the 'Balance' control other then leave it centered anyway) (yes, we lubricated the bushing to no avail). Also, one of the speaker output clips on the 'Rear / Matrix' is missing it's plastic tab. You can still lock in speaker wire, just need something small to press it in. Finally, and cosmetically, there's a minor scuff on the dial window (see photos above).
By design, the unit does not have a 'DC Relay' for turn-on, so there will be a thump through your speakers as the power supply caps are charging up.


 
Again, as stated before, we have completely gone through this MCS 3235 Stereo Receiver, cleaning and testing all and it gets our full 'Certification'. It is in fabulous cosmetic condition! Looks, performs and sounds great! Measures 18.75" wide x 7.25" tall x 15.5" deep and weighs 30 lbs unpacked. Includes our standard 30 day limited warranty.

#...7457
 Circa 1976-'81
MIJ
SOLD 6-12-13

ü  Our technician has completely gone through and 'Certified' this unit.  

ü  Everything was cleaned inside and out
including all contacts, switches, controls and I/O jacks.  

ü  Control Pot shafts re-sprung.
Internal and external fuses checked and replaced where necessary.  

ü  Bad driver board capacitors and transistors replaced.  

ü  Slightly leaky TO-3 output transistor replaced with
an exact and original transistor we had in our 'private stash'.  

ü  We also extensively aligned the tuner front-end,
as well as the 'MPX' circuit for optimum AM & FM performance
as older internal tuner components have always drifted
on vintage gear over the years. Generally AM reception
in a stereo receiver is treated as an 'after thought',
but the AM reception on this Rotel RX-803, #...7457 is pretty decent.
Great sounding FM tuner on this receiver. Very clean, punchy and musical following alignment.  

ü  All dial and meter bulbs replaced.  

ü  DC offset and driver board / output bias current set to correct values.  

ü  All inputs and functions tested, and both amplifiers produce
clean and even sine waves into static 8 & 4 ohm loads!
No power supply hum of any kind. It's dead silent! All functions test fine.

ü  Unit has been thoroughly detailed inside and out.

ü  Following restoration procedures,
the unit was run continuously at medium volume,
as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours and into a 4 Ohm Load!
Only cosmetic issues are a bit of minor wear to the face,
including a small blem to the silver plating (see above photos).
