[AMPS] RE: HV Power Supply Confirguartion / rectifier

[K7xq@aol.com]

Thanks Carl and others,
 In studying my ARRL Handbook at basic rectifier circuits and the way it looks like it may have been connected. It strongly looks like a voltage doubler circuit. There are two rectifier diodes uses. Two of them tied together at one end that also go to one end of the transformer.The other end of one rectifier goes to the (+) side of the filter, the other end of the other rectifier diode goes to the (-) side of the filter bank. It looks like the other end of the TRANSFORMER goes to the "CENTER" of the filter bank ( three capacitors on each side of where this point looks like it might have been connected ) rather than the end of the filter bank. The filter bank consists of (6) series 450 VDC 480 uF Capacitors with each capacitor shunted with a large 25 K resistor.

The only other questions is where the voltage meter connects. It looks like it was connected at the next to the last capacitor (+ side ) before the last ( last capacitor being the clostest to ground ). Does this sound like the right location ??

                     Voltage meter tap ???
