Sorry just looked at the diagram for your set. I thought it was a set with a power trans and SW. You got the economy model with a voltage doubler and series strung heaters.

Hum
Have much do you hear? A lot or just a little?? I would suspect that this set may have a little bit hum just from it's design.

Check the pins on the tube and socket. I'm presuming that you've replaced all the paper caps? C 403 or the mica C405 could be your culprit. Did you measure the resistors when you had the caps disconnected??
