Dear,
I have a SWR LA15. The amp sound ugly and distorted . And the the cap Q8 starts to get very hot and inflate.
Observing the voltages (Photo attached). It seems that the Bias is not correct. But I suspect that some component is wrong.
I am also not clear on how to do the bias adjustment correctly.
Do I understand that I should have a voltage drop in resistors R3 and R4? Is correct?? How much?
