That is an excellent idea! a 70 volt speaker line matching transformer:

Hi!

Member Schmitt Trigger, thank you – I'd forgotten all about 70V/100V line transformers – an Eagle P037 is just about the right size and power–rating for a Huntron high–voltage project and is designed for operation at the audio frequencies used!

Also it's primary can be driven from a cheap eBay diy kit power amplifier module, leaving only the oscillator bit now!

Thank you for your input – I know about 100V p.a. working, but hadn't realised small 100V transformers less than 10W were readily available!

there is a nice supply for such a tester, that goes up to 80V here :

At my old work, we had a Huntron 2000, which spent most of it's time unused.
Only one bloke seemed to have success with it, & swore by it---- the rest of us swore at it!

I tried it once, comparing between a good & bad board, with no satisfaction.
My feeling was that if you had a spare good unit, you could compare normal operating voltages, waveforms, etc easier.
I could see that if you were testing a lot of identical boards, it could work for checking them against a good board, without needing to fire the complete device up, but that was rarely the case with our work. :-DMM

The Huntron Tracker is like Vegemite. Definitively an acquired taste.

For the record, I love both the Tracker and Vegemite.
Vegemite and avocado......delicious.
