Art-13 Power Supply

[W7SOE]

I am in the "parts gathering" stage of building an ART-13 power supply.  With regards to the HV supply, I would like to provide up to 1500V, adjustable via variac.

Am I correct to think that I will need a 3000V CT transformer if I use a couple rectifier tubes (.6366Vp ?) and that I would need a 1500V non-CT transformer if I used a solid state bridge?

Thanks

Sounds right to me, Rich.  Don't forget to compensate for the voltage loss across the rectifiers, etc. if you go with the tubes.

Gud luck!  It should be a heck of a rig.

Thanks Rick.

Anyone have experience with Antek Toroidial transformers?

Thanks

Another question.  If, for example, I need 400VDC and I have a 900V transformer with CT, can I use it with the CT grounded and two solid state diodes?  Basically the "tube" configuration" with the tubes replaced by diodes?  These would be very high voltage diodes I suppose....

I am looking for the three transformers I need (to produce 1500VDC, 400VDC, and 28VDC) and would like to know what my options are.

Thanks

There is a thread here on this site about the 400 v supply.
