As we've had a number of these, we knew that it was likely the "Balance" control potentiometer. It was the issue, so the pot was 'jumpered'. Fairly 'excusable' work around as most folks are typically leaving their 'balance' control turned to the center 100% of the time anyway. While this is a fairly versatile pre-amp, that we 'still like', it does have a few 'difficult to service' issues and a couple of 'semi-permanent' defects. Firstly there's a fairly common issue with the 'balance' control pot. It's anemic / fragile in the first place, which makes it prone to 'breaking' in such a way that it will drop channels. We have not found a replacement. There are a couple of websites that have photo essays on doing 'micro-surgery' on them, but it's very difficult, time consuming with sketchy results. Probably the most practical way to address the issue with the balance pot is to 'jumper' across it. It can either be left in place or removed once jumpered. The same 'fix' can be utilized on the 'Headphone' level pot, then simply use the main volume of the pre-amp to control the headphone level (like EVERY other unit does).
