Solid state versus tube rectifiers in a PSU

[TonyTecson]

oops I meant full-wave above not half, I always mix that up.

perhaps you mean full wave voltage doublers?

PSU for B+ and dc filaments...main B+ can be a fwb, or full wave doubler...

Here's my "DBLQUAD" - my main PSU board for the modular amp, which has the doubler and quad.
and the second "RC filter" board which has 2x330µF -> 5R -> 2x330µF.
No ground plane - not necessary IMHO.
No fancy caps - also not necessary IHMO.
