so you think TR41 is ok then? Nomad was saying that front leg should be about 6.8 volts which is what the schematic says too. Full voltage seemed to much? But I suppose that could be ok because if you’re saying TR41 goes dead for SSB and there’s no output on SSB either, then likely the problem is somewhere else?

As far as the power supply: Those caps could be causing the higher voltage? Still trying to understand why the voltage was so high out of the power supply board. The main board voltage returned to normal once I switched through a DC power supply instead of the AC so I figure the problem must be in that power supply board? I have a 10uf cap I can sub in for the 220. But the zener and the big cap underneath I have to order. Also it looks like the bridge rectifier is not the original. Can’t really tell the number on it but if that’s not the right one that could be causing the higher voltage I assume?

I will put the 10uf stock back on the power supply board. All the electrolytics in this radio have been replaced.

Back to no power out: This original issue with no power started with bad SWR. There were key ups for only a couple of seconds here and there trouble shooting it but maybe that caused all this. But I replaced the final and driver and still nothing.
