You only loose a bank of caps once before swearing off "bargains".
Ive nothing against quality brand overstocks or unused surplus with 5 year
old or so date codes. Most commercial amps use caps with a 20-25 year
trouble free operation but then its time to spend the money on PM.
I test all incoming caps at actual working voltage with a Sprague TO-6A
current limited cap tester and then on a bench supply to test at up to 500
ma. Not a full test but it gives me a fairly warm and fuzzy feeling.

It would seem that there are a number of us who are very dubious about
such capacitors for this application. In view of the price, I figure that
because of both that and the lack of data on ripple current, they are best
avoided.
caveat emptor!
