[R-390] 26Z5W replacement

[David C. Hallam]

I know this is probably heresy but Ted Weber at Weber Copper Top will make a
nice plug in SS replacement for the 26Z5 complete with voltage dropping
resistor.  I've used them in my R-390 for some time now.

Hey Barry,

Is there a possibility that a 12BH7 dual triode could be wired as a dual
diode? I'm not sure about the current capability but it has some good power
specs and should have the reverse PIV because of its service as a vertical
deflection amp.
