Dear Asylum,
This is what the Asylum is for, and why I belong in one.I am trying to make this little amp as cheap as possible (el84 SE), and I am thinking about using a doubler supply straight out of the wall, with no transformer. I am thinking of building in a voltage transient suppressor, and a current inrush limiter(both cheap). I am looking to use two 110uf 450V lytic caps in the doubler supply, with two 3A 600V diodes in series for each leg. Then the supply will follow RCRC, with the next C a 200uf, 400V lytic, then a 47uf 400V SCR Polyp.
So, is this insanity, or something sensible.
Questions?
Thanks,
Sincerely,
BRent Barr
