[Hallicrafters] HT-37 initial test

[bill kipping]

Hello to the group, I have an HT-37 I bought 8 years ago from a honest fellow at a hamfest , said it worked well. Time to try it out. The power supply is unmodified an the transformer looks origanial. I plan to remove/isolate the 5V windings and replace the rectifier tubes with Weber Copper tops before bringing up on a variac. Anything else?  Tnx Bill KE7KK
