I have -6.37 @ the test pin . It will not move . All parts were tested and P1 was removed and checked ..... V @ Q4 & Q5 gates are stable in the 30mV range .
Is the fact that I'm using the 2.2k @ Q2 the problem ... ? I only have 3 ZVP so I want to be sure as I can be before I plug it in .

With the 2K2 resistor you are indeed unable to modulate DC offset to your needs. Because resistor has only 2 pins and no gate (command) pin 😀
Try the ZVP in. I have some spares that I could send to you, in case you run out of stock 😉

I have a problem with the Voltage @U1 ....- 1.5 VDC .... I think the reg is gone ... R1 reads as it should , but no V on the out ...?

I changed to + Reg and its working ,but now I'm showing 23.55 V @P1 test pin with no adjustment working .... I'm trying to use the other board V's to check this board ...
Here we go again !
3 V drop across R6 ,
Here we go again !
3 V drop across R6 ,
changed Q11 and no change
S= 23.76
G= 22.36
D= 22.85
I think its somewhere else ... 🙄
Hi 6 ,
I have a fully working board ... just one to go !
😀
I don't understand the technical aspect ... I just took the measurements asked and did as I was told ....
I have to give credit to the French Connection !

Thanks Wayne ,
I guess a job is out of the question 😱
its easy cus I'm special ! I had this problem before .... When I used a 1 amp fuse at the very beginning.
I may order a new board in the new year .... I just replaced the pos reg !
Any opinions welcome ? New board , new parts and start again ?
