[R-390] Tantalum or not Tantalum

[Ed Tanton]

I disagree... there is a significantly different (lower) ESR for
tantalums from 'regular' electrolytics. This could affect the loading on
whatever stage is driving through it. While it probably wouldn't matter,
I feel the more conservative approach would be to use the same type as
the designers intended-e.g. a 'regular' electrolytic.

Electrically, it doesn't matter in the least.
You can put in anything you want, tantalum, aluminum,
whatever, as long as it's 8uF or larger, with a rated
voltage of 6V or more.  when I have to do one, I'll probably use a 22/16
axial-lead aluminum, since I have many of those. The temperature under
the AF deck is fairly high, so best would be a cap rated for long life
at 105 deg C.
