2270 Power board problem

[Bozobigsky]

Marantz 2270 power board, replaced the caps and the small transistors, checked h805 and it looks ok.
The trouble is that I can't adjust the output to 35 volts. The trimmer r809 has been checked and it looks ok.
Turning the trimmer doesn't change the voltage between j803 and j802 as the manual says it should though it does change the voltage to
the base of h806.

Thanks for any suggestions..

Maybe zener H807 or rectifier H801,2, or H805. Suggest carefully measure Vdc at H806e, repeat for collector
