Hi Jon,

My students and I have been using these cheap transistor testers

They will measure fairly accurately inductance and capacitance. It
should save you from this problem in the future. You can get them
cheaper elsewhere.

After my recent experience discovering the bad capacitor only after
almost complete disassembly of the filter, I'm considering getting an
LCR meter but there's only one catch in my case: it has to be low cost.
I know low cost and reasonable quality stay mostly opposite but in
today's market, the relationship between them has increased...
sometimes.? So what would you recommend? Someone recently suggested an
LC-100A, but then I read that it can arrive with issues that make
reading of low value components impossible.? I suppose I could go that
route as long as it had free returns and only from China as the US
vendors are too expensive for me.

Thanks in advance.

Jon
