Hi all. I have an old Mosrite SS amp that I am working on getting back into good working condition. It had a few blow transistors in the output stage (as well as a couple light bulbs?!) and I have replaced the suspect parts. When i fired it up and scoped it i noticed I was getting a fair amount crossover distortion. I adjusted the bias pots to eliminate it visually and it sounds pretty decent as is. I know there is a more scientific way to do this, involving math and measuring voltage across emitter resistors. Just wondering if anyone could assist me in figuring out where to measure this and what I should be looking for on this particular amp. Output transistors are 2n3055 and are q30 and q31 on the schematic. Thanks!
