I found some very cheap 48V CT (2A) transformers, and will play with
them. I would think that PS ripple will be poisonous to this circuit,
so I have hatched a hare-brained scheme. I wonder what would happen
if, after the diode bridge and, at least, a very small cap, you ran each
leg through the secondary of a transformer like (in this case the same)
as the main transformer. If you then connect the nominal primaries of
these two transformers so they oppose one another, would this act like
a conventional PS choke in a tube amp? My goal is something similar to
a choke input supply without having to find and pay for a monster, high
current choke with enough inductance. This seems too simple to me, so
I'm expecting to learn why it's not a good idea.
The transformer in the picture is an EI 40V CT that was on closeout
at Parts Express.
