Hi
I used an oscilloscope to test V3A&B. The 8-pin output signal of V3 is normal, which means that the signal strength is normal before entering EQ control, at 470pf. The signal before the two 0.022uf capacitors is normal. However, after passing through these three capacitors, it is impossible to measure the signal on the EQ potentiometer, and of course, it is also impossible to measure the signal on the vol potentiometer. What are the situations that can cause the above problems？

Did you mean to post this twice ?
