So This kind of complicates the troubleshot because I previously checked Q401 and it checked out ok so don’t think it’s that and Those 3 resistors are stock original values so do t think it’s that. Didn’t touch those 2 smaller transistors.

Like I said I ordered new zener. I had an extra 2sc1419 which is the other bigger transistor on that board so I swapped that out too and I guess I will downgrade that 220 UF back to the 10.

What about the bridge rectifier causing that increase because it’s definitely not the original one?

in the meantime like I said I’ll power it through the power supply instead of the AC line because that restored normal board voltage. But would like to get to bottom of that power supply.

However the no power out is certainly my bigger concern.

I think I have literally had an issue and repair in every area of this radio since December. Modulation strip, receiver, synthesizer, power supply, TX strip. So frustrating.
