Well mine died the instant I'd touched the knob. If that's really the case, something is very wrong.

If you are just doing it for fun, and you're not that invested in the outcome, then great, but if you really are counting on it to look good in the end, you might want to skip this set and look for something cleaner that is obviously low hours

This is mostly a challenge project; after all this is an obscure set and is worth some effort. I got it for free anyways! and I'd also like to be more comfortable working around high-voltage electronics.

How exactly would I do this with my multimeter? also this measurement would require a new HOT. Two new HOTs should be arriving tomorrow & the new 1500pf safety capacitor arrived today.
ALSO it'd be nice to have the Sams' for this model.
