Hello again,

My main thread is " 2712 SA with display (and normalization) issues".

Due to the large number of electrolytic caps this SA has, I wonder if
anyone can recommend a (not too costly) in-circuit ESR capacitor tester I
could use to narrow down problem caps that otherwise show no obvious signs
of failure (i.e. leaking, exploded).

I've seen the tweezer-type LRC testers, and they might work for in-circuit
SMD capacitor testing, however, thought I'd run this by everyone first,
since I have no experience with such in-circuit cap testing/testers.

Creating a new Topic, since this is a generic question.

Thanks in advance,
