I'm building a power supply for two 12AX7 tubes. I am wanting to use a 20vAC wall supply, and then use a voltage quadrupler circuit to turn that into 160v. I'll then use a voltage divider to provide 3.2v to the heaters in parallel. Draw for the 12AX7's seem to be roughly 400-500ma. So, a 2A 20v supply followed by a voltage quadrupler and voltage divider to power the tubes and heaters would work?
I've did all the equations for capacitance, would I be able to get adequate power from this circuit? I'll be using 220uf 300v filter caps and 1N4007 diodes.
