I have a article for building one from a past audio amateurs mag. If I find it I’ll post it.

rackmonkey said:I saw this when he posted the first video. Interesting. I’m about to start building one to play with. I have a Heathkit IT-28 that I restored a while back that I currently use. I intend to compare results with that. Will report back what I find.
Also, wouldn’t this post be more appropriate for the Chamber than the Brewery?

scott2000 said:What are these other tests you mention???Any links???? I've kinda heard about using a megger before but never dove into it......... the eevblog ...current.....??? Sounds interesting.....
scott2000 said:Ok cool!! Yeah I like this guy.Has tons of good info on his channel
Love his plate current video using transformers....Such an old method but I never knew about it before....
Thanks!! I'll check these things out...
The point here is what is acceptable leakage. The answer is "it depends on the rest of the circuit". For example, a coupling cap must have a low enough leakage as not to disturb the operating point of the subsequent stage. Actually, there would be a significant difference between a bipolar and a FET stage.mjrippe said:The video makes a point about how his low voltage tester catches bad caps that the HV ones don't.
A simple device as the one I just described can be made to detect a wide range of current. It is up to the user to define what is acceptable. Once a value is read, it's easy to compare it to a published spec or determine if it is susceptible to impair the circuit's operation.There are a lot of factors to consider and any tester is only capable of checking a few of them at best.
