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

The Utracer is good. I have an earlier one that goes to 300v
Yes, I know, but in reality as great as the UTracer is I don't really use it very much. Therefore my priorities lie elsewhere at the moment.there’s an affordable kit to update it to 400v
I do know the uTracer. Just posting this as an interesting tidbit.
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.It's cool and thanks for sharing, but I don't see it being useful by testing tubes at such a low voltage
