I recently build a CK2III amp. However I think i damaged the transistors, can anyone help me verify that the transistors are indeed spoiled from the voltages in green?
The +15V and -15V test pads on the board are 15V and -15V respectively.
There is no sound produced when i plug in headphones to test.
Any help is greatly appreciated.

Hi, I hope you found already. From the picture I do not know, but I know that I have killed a  Q19. In this circuit it is easy to find, because no guarding or removal needed, you can measure them with a diode meter, in circuit.

Use this BJT sanity check tutorial to test all transistors (except Q1 to Q4).

Check Q5+Q6 base-emitter "diode"
