Amp channel cutting out - what to do?

Recommended Posts

A week or two ago I snagged a used GS-1 from HF (from doobooloo). It arrived and I let it adjust to room temp before firing up, and all seemed well until the left channel cut out almost completely. Flipping the high/low gain switch seemed to almost fix it.

I contacted doobooloo and he said that it was a common problem with some GS-1's with the DACT stepped attenuator, and that popping the lid and reseating the molex-like connector for the left channel at the DACT SA would fix it. It did... for about 10 days. I noticed it again today, and so I popped the lid and reseated again. The molex connector grips firmly and none of the pins seem to have any play.

So... is there any goop I can slather on the pins or the connector for a more permanent solution? I doubt I can vibration-proof my apartment. (And certainly not my desk. Undergrads make me pound it with my fist at least once per week).
