70.171.34.17
Hi - While cleaning (well, kinda) up my shop I found a bag of mysterious parts. They were probably part of a flea market parts haul several years ago. Camera batteries are dead, so no pics but . . . they're multicolored like "tropical fish" caps but smaller - about the size of a very small ceramic, with similar radial leads, except that the body is more rounded - about the size of the head of a kitchen match. Colors are red on top, orange in middle, yellow on bottom and on one side there is blue, which covers all the other colors along that edge.What do I have here? I assume it's a cap - it measures 240 nano Farads. Is it a tantalum or ???
Any particular place these were used - or place where they shouldn't be used?
Thanks . . . Charlie

Sounds like Tantalum. I never liked them. They tend to become leaky or short out. They have polarity, and not always clearly marked. Some may have a red dot at the positive lead.

I think tantalum caps were fashionable for a while in the 1970s. Leslie used a few tropical-colored tantalum radials in their solid-state models from that decade. They cause problems, so I generally swap them out for good quality aluminum electrolytics for the sake of reliability and sound quality.
Sounds like a tantalum cap to me.
