Greg- You are correct about the 5 Volts; I checked the tube info. My 84 schematic says 50V for the "Filament Volts - F to F" under "80" which is what threw me off... am I reading this wrong?
Follow up info- I checked all filaments for all tubes - all are good- about 6.3V. I also probed from the first filament to every place the other filament connected (caps, resistors, tubes) and all show the same voltage (5.7V). If my tubes were not glowing but had red filaments, does this indicate the type of problem it may be? I'm not sure what to check next. Thanks guys-
