Mid Nineties Twin Amp ( 100/25 watt).

Recently, When played loudly at shows my amp switches in and out of channels on it's own. I do not use my fender channel switching pedal. I only use the clean and the middle channel not the gain channel. It only happens when played at louder levels and sort of flickers in and out of seperate channels. I have had the thing retubed, looked over etc. and have had the amp to a few different techs and still no solution.
Before I chuck the thing over a bridge, Does anyone have any ideas or have had a similar problem that they can direct me how to go about fixing the amp? Any help will be much appreciated.
Thanks

I am no technician or anything close to that. But I remember a discussion about an amp with a similar problem and a few resistors needed to be changed to solve the problem.

I just fixed my good buddies that had that problem the other day. Turned out to just be a few cracked solder joints. I think he had maybe six but all is good now. Pull the chassis or tell your tech to look at all joints and resolder where needed.
