No, you need an ESR meter to check the small 'lytics. Your VOM will only tell you if the capacitance is correct. Bad caps usually read the same capacitance but have a high ESR.

I knew it was time to pony up the money for an EST meter. Fortunately the are not very expensive.

Dave, not the go off topic too much but what is a good and inexpensive ESR meter?
I'm assuming my Heathkit CT-1 isn't very useful.

Hopefully an inmate with more experience them me will chime in. I do repair, but it is pretty basic stuff. Actually, I suspect that as long a the Heathkit is functioning properly, it will do. I don't think it has to be that accurate to see that a capacitor is out of commission.
The Blue looks interesting but I don't really know if it is good (see link). I to have a vintage tube ESR meter that was given to me by a retired TV repair man, but I need to bring it up to spec. He thought it was still usable!
