What is the correct plate voltage for a 50watt plexi using the 1202-118 PT? Metro's is listed at approx 440 VDC, while Marstran's and Mercury's are listed at approx 420 VDC.
Thanks!

Somewhere between 420 and 440v depending on when the winder ran out of wire
I have seen both on original Drake 50w PTs from 67-69.

The plate voltage for my 1202-118 comes from actual tear down numbers and from measurements on from my 68 50W that has 420VDC on the plates as well.
