Hi Rod,

thank you so much for the fast feedbacks.

I tried again between a B- at the electrolytic and pin 3 of the XXD and I have 56 VDC and B- and pin 6 XXD 84 VDC.

Do you mean resistor 22 and 26 ? I am sorry I am not and expert and following the schematic and the connections into the radio I think I found the point you mention after the first 10K resistor that is connected on one side to pin 6 of 35z3GT ( 100 Volts ) and the other side to pin 3 ( 84.3Volts) of the 35x3GT together with the capacitor .01UF that is connected to pin 7  ( 3.5 Volts) of the XXD

Thank you so much for your help
