Steve:
If you want a sure bet, pick up some Sanyo Oscon caps.
These are superior quality organic polymer electrolytics: High temp,
very low ESR, very long life...tantalum replacement grade and come in a
wide range of values.
They sound great for audio coupling too.
Check the Sanyo site for specs. Real high grade parts.
They can be found on ebay from Asian distributors and sometimes from US
surplus dealers...no idea where to buy at retail.
This is what I used. Pretty much the best you can get in a wide range of
values.
Watch out for lead size though. I bought some 15uF on the 'bay and the
dang leads were too thick to fit through the PCB holes.

I am the initiator of the prior thread, but since my Omni V is still
sitting untouched on the work table, I am still interested in doing the
recapping properly. I have been seriously considering tantalums, since
they can have a much longer life than electrolytics. But, I also know
from my boatanchor experience that circuits which were designed to work
with crummy cheap capacitors, can sometimes have stability problems with
modern, much higher quality replacements. What sort of tantalums might
I expect to be decent, longer lasting replacements to the caps in the
radio, now? There are plenty of different types and ratings, even of
tantalums. I would rather do it right now, than to have things go bad
in a few years again, and discover that capacitors with leads, which can
be (shudder) soldered with tin-lead alloy are no longer available.
What sorts of caps and specs should I be looking for?
Thanks,
