I found this on Lundahl's pages. The rectifier is what I had in mind. two diodes and a vacuum diode. I had been talking of the 6CA4, it is a tough tube. peak current capabilities to allow a 40 uF first capacitor specification. We'll be treating it quite gently with a choke input filter.Either way, I offered help, and it is *NOT* conditional on following some specific design I happened to dream up. I have small bits of time, and the schematic is on a temporary hold until I can have longer ones. I do hate keeing you folks in suspense.
Merry Christmas y'all!
