Hi Guys,
i need to build simple PSU for microphone with one 6028/408a tube.
Filament: 20V/50mA
Plate: 105V
I have transformer with secondaries:
200V/40mA
60V/70mA
10V/200mA
For plate voltage, my idea is to connect 60V and 200V windings in parallel - lowering voltage to 130V and get higher current supply.
For heaters voltage, my idea is to use voltage doubler.
Schematic attached.
Could someone check that for me?
Is it filtering enough?
Is this configuration of voltage doubler would be ok for current load?
