electrolytic capacitors

[Chuck H]

Neither end is metal so I've installed backwards once or twice without that big visual cue.

I dare say these may be radial caps stuck into an axial can?!? Probably better caps for it too. Since most of the new machinery, refinements and just general progress and focus has gone into radial caps I have found the best options there. Axial caps are only made to support a small market and IMHO they aren't given much consideration. You're lucky to find basically serviceable caps in axial format anymore. I changed to radials because I could. I build custom so it's not a problem. I'm not cloning anything and I'm not doing vintage restorations. I feel for the guys stuck with axial caps anymore.
