Granted, it only goes up to 24V so far, but maybe worth watching for future developments:

It's cool and thanks for sharing, but I don't see it being useful by testing tubes at such a low voltage

Of course, not for our applications. However it is such a simple design that perhaps it could be expanded on. Could end up being a less expensive option for folks who test mostly preamp or microphone tubes.

even preamp tubes and microphpone tubes use a much higher voltage than 24v.
