[sdiy] Tantalum alternatives for re-capping?

[cheater cheater]

You can turn any SMD part into through-hole by using two pieces of
solid wire and some heat shrink.

Personally, for simplicity, I suggest using a modern, high quality,
through-hole electrolytic. They'll have better behavior both for audio
and for rails than tantalum caps while remaining a similar size.

For DC blocking caps I suggest MKT capacitors.
