I bought about 100pcs of the disc ceramics from Mouser when I found one at about 10c apiece. The yellow ones. 10nF.
Not that I see them helping much.

I am not bashing anyone, just to remind that the price is not a/the criterion for buying electrolytics.

To me:

1. Ripple rating + temperature rating.
2. Brand. (no no-names or Roobycons or Nippicons).
3. A reputable distributor.

I always buy high ripple current rated caps. Suffices it to say that today's smaller caps even with the highest ripple rating are barely adequate for the large old radio repairs unless paralleled and such. And when we stuff them into the old shell this unimproves the thermal conditions by that much and so it becomes only worse.
So buying cheaper usually gets you a "general purpose" type even if from a good brand. Play this radio continuously for long time and you will see premature failures.
