Hi. I have this old 100 watt/channel amp which I bought more than 20 years ago. Twice now I have opened it up and tried to clean the switches and pots the best I can using Deoxit because one of the channels would cut out. I am pretty sure it was the input selector switch that is the problem because if I messed around with it, the channel would temporarily come back on.

But each time after just a couple months the problem returns. Is there any way to repair this unit or is it time for a new amp? Thanks.

PS- Anyone else have a helluva time typing text into this dialog box?
