Default Re: Homebrew Valve Tester

That's an extremely elegant design.
And a stroke of genius to make it compatible with the AVO VCM settings!

If I hadn't acquired an AVO VCM at a very reasonable price decades ago, I'd definitely want one.
And I'd still be tempted to build one if a kit came out...

I'd like additional filament/heater voltages of 1.4-117V, though.
I could wind a vaguely-suitable transformer from my Louth kits, same tappings as the AVO, but could you (or anyone else) perhaps design a switch-mode regulator to suit, please?

Congratulations again,
Martin.
