can someone tell me the position of the transistors on the pcb
I have an amplifier and the transistors are missing

 

[Perry Babin]

Which transistors are missing?

 

[jimakos206]

All the transistors are missing

 

[Perry Babin]

In the entire amp?

On the driver board?

Is this a photo of the driver board or simply a similar board?

 

[jimakos206]

It’s the pcb of the power supply

 

[Perry Babin]

All transistors are in the circuit, in the photo. Are they un-marked or defaced?

 

[jimakos206]

As I said above all the transistors are missing in my pcb . Someone has tried to repair the amp and has removed them

 

[Perry Babin]

I asked if the photo was your board or not.

Are the missing transistors the driver transistors that drive the PS FETs?

If so, the PNP drivers will typically have their collectors directly connected (0 ohms) to ground.
