Update- I may be getting closer. I received the great schematics from Chuck and dove back in for another round. The filament on the incandescent lamp was shot as well. So I replaced it with a #47 (which is as close to the spec as I can find....although I may want to try a 12V bulb instead of the 6v one....) and checked all interconnects, etc.

I fired it up- as son as the rectifier tube (my last good one!) started to operate, the pilot/incandescent lamp got waaaaay bright. So I shut it down fast. My guess is that this is how the last two rectifier tubes died... so I am now scratching my head as to why this is occurring? I thought that the rectified power circuit and the circuit for the heater elements for the tubes was pretty much independent, but I guess I am wrong.

Maybe I have a bad replacement cap? Anyways, It may just be that I am putting the wrong pilot lamp bulb in, but I don't think so....


In any case- thanks to you all for the help and I will keep fiddling with it!
