Ordered some supply chokes and transformers for the 170V and 500V supplies. I've added four windings on each B+ transformer so I have some room to play with and not end up with more iron in the future that is a one trick pony. The filament windings have been moved to their own transformer to allow seperate switching to let the mercury diodes warm up before applying high voltage to the anodes in case of the 500V supply.
There is a seperate 24V winding that powers a relay which, when not activated, will add a load to the B+ line to drain the capacitors and not leave the B+ on the system.
The 170V supply to power the 26 and optionally the 4P1L driver. (error: it should be using the 200V winding with the 1µF cap)
The 500V suply to power the 801A and optional 10Y driver tubes.
