If I were homebrewing an amp I would not even bother with
electrolytics; I'd use one or more oil caps to get 40 uF and call it a
day.
If the power supply is to supply a fairly static load, I'd use a filter choke.

The electrolytics make sense only if you are doing a restoration job
on a commercially manufactured amp for a customer.

If rolling your own, build into a rack cabinet and go with oil c.
fewer caps; fewer problems long term.
