Members khastra_ksc Posted January 24, 2012 Members Share Posted January 24, 2012 So I got a Sunn SA-21 power amp on Ebay on the thirteenth and then proceeded to get fired from my job... So I haven't been able to test out the amp until today. Anyways, when I turn the amp on, the B-Channel's limiter light is always on. The sound is just barely not as good as channel A, and the volume for it works normally, but it doesn't really matter because after a few moments it cuts the signal. If anyone can help me out with this I would greatly appreciate it because I am running out of time to report this to Ebay. This is what I get for putting {censored} off!

Members Reauchambeau Posted January 25, 2012 Members Share Posted January 25, 2012 hard to diagnose without knowing the chain. if you switch the input cable from A to B, does it still do it? if so then you know that it's not wwhat you're feeding it and it's an internal amp problem. does it have a mono/bridge switch, and is it activated? if you care to describe in detail how you're running it I may or may not have some ideas.good luck Link to comment Share on other sites More sharing options...
Members fretless Posted January 25, 2012 Members Share Posted January 25, 2012 Have you tried each side by it self , does it bridge mono ? Did you try it stereo ? IF after all that it still f's up , report it asap Link to comment Share on other sites More sharing options...
Members khastra_ksc Posted January 25, 2012 Author Members Share Posted January 25, 2012 I have tried all of the above, actually. I am kinda sad about it. I was going to sell my current power amp for twice as much as I bought this one for. Link to comment Share on other sites More sharing options...
