My Yamaha Ax-700 is only putting out like 50% of the lows out of the right channel. I have done all the usual set up testing to see that is indeed the amp that is at fault. So far we have tested and/or replaced all of the transistors on the RH output as well as replaced two ECG 90/91's out of the right. Any other suggestions on where to look next. I am no engineer. Is it in the preamp section? Please help I love this thing. It's killing me to see it not at it's best.
