Here's the schematic and the transistors I need to replace:
I took a picture of the schematic thats inside the amp instead of posting one from a website, because they're all so grainy online its too hard to read. I zoomed in on the last one to give you guys a better look at Q302, Q303, D210, & R216, since those were the trouble spots. Fyi, I've replaced all electrolytics, all 8 power transistors, a few diodes and resistors, and a few of the smaller transistors hoping that it would solve the problem since I can't find the drivers. Now, when I play it, it works, but only at very low volume. Turn it up slightly and it distorts and makes loud "coughing" noises. Same noises happen when I tap or jolt the amp at any volume. Solid State is such a pain to work on.
