Good morning, all. I just finished re-wiring a 39-30 Chassis Code 121 table set and will be firing it up today. I suspect the power transformer is bad, but would like to get
a set of voltage reading specs if anyone has them. They are not in the two service bulletins I have for this set. Anyone have something easy to use, short of having to pull the specs tube by tube from the site that has tube specs and base diagrams?

If it does test bad, anyone have a good transformer to sell? Looks like this one's been replaced by a close substitute many years ago already.

Regards,
Clarence
