From the circuits i viewed all rectifiers were tube rectifiers. Then i noticed that the overall power consumption is not so large. Even the power tube consumes no more than 50mA (relatively). Well i know for sure there are diodes that can handle 500V at a few amps like BYT79-500. Why the need for a tube rectifier? Can't we just make a voltage doubler and get it to the volts we need?
