[GreenKeys] Tube loop supply

[amourdutigre]

Does anyone know where to find a schematic for a 60 mA loop supply that uses a vacuum tube rectifier? Can two filament transformers with their secondaries connected be used as a line isolation for such a thing?

Thanks in advance!

P.S. I am having a blast playing with my 28 ASR! Got it working on heavy metal!

Next project...getting the TT/L-2 recapped and working again.
 
Then, I will be ready for ITTY and real RTTY.

Best and 73
