Could someone provide a circuit description for Q202 and Q201 in the Driver_Bias part of the schematic?
I'm also have a problem setting the bias on Q207 (Q208 is OK). I increase the pot to approximately 90 percent, at which point, it suddenly jumps to an excess bias amount. Way too touchy to set it to +125 mA. Could I have a bad pot? This happens regardless whether I set Q207 first, or second.
Thanks a bunch!
