J3 Vpp is set correctly at 2-3
My pcb has only two types of transistors, S8050 D 128 for Q2,Q5,Q1 and S8550 D 126 for Q3,Q4.
Read Vpp Switch transistor wich i think is Q4 and emitter is at 22,20V.
Thanks.

No Vpp on dual powered willem
Hi all,
I have this dual powered willem:

But now there is no Vpp, mesured Vpp in Test HW and there is no reading 0v.
Can anyone help me to figure this out.
Thanks.
