[Hallicrafters] Re: [Boatanchors] Replacing rect tubes with diodes question

[Bob Kulow]

Whenever I replace a rectifier tube with silicon 
diodes, I change the filter circuit from capacitor 
input to choke input by reconnecting the first 
electrolytic capacitor to the "downstream" side of the 
filter choke or resistor. This lowers the B+ somewhat 
and improves regulation as well.

If the audio output plate is directly connected to the 
rectifier cathode, though, this won't work.
