I haven't started on checking anything yet, Mark. I did check the finals to make sure they were ok and I have an extra set I can use later if needed. One issue I see is when the VOX switch in place in the PTT/STNDBY position, the transmit relay energizes. I will let the group know what I find in the days ahead. Any suggestions would be appreciated. The radio has gotten hi reviews so I an glad to have it and look forward to restoring it.

On some of the older Yaesu radios there was an octal socket that required a plug with a jumper to be plugged in, I cannot remember if that was I order for the radio to operate in general or to transmit.  I think it was to operate in general but a look at the schematic would tell. It could be a weak tube, either an oscillator or driver/final tube.  Is the high voltage present on the final tubes? Is there current draw on the final tubes when the transmitter is activated?
