Hi,

has anyone experience with this thing?

I have build one for my SOZ, and - you can hear no hum or buzz at all!


when i use a conventional Capacitors PS of about 400000 !!uf per channel a small buzz is hearable!!

BUT: the TO3`s get extremly hot at about 20 volts per rail (90 degrees !!), and i want to increase the voltage to about 60 V per rail.

I think, with increasing the wattage of the SOZ and the Capacity Multipler i need to build a case for the amp as big as a refrigerator.

Yes, capacitor multipliers work great.

On the dissipation side, if you are using a Mosfet, then
the wattage will be the Vgs (about 4 volts) times the
current, and that will be all of it.

If you are using a bipolar, then the drop across the
device will depend on the resistance you have on the
base. If the Collector-Emitter voltage is much more than
say 2 volts, you can reduce it by reducing the value of the
filter resistor.
