I finally got around to documenting this HV bench supply that I designed and built a while ago...

Details, schematics, etc. are here:

Just as I had managed to get all components to Bruce Rozenblits PSU ....

On the other hand - a friend of mine has scrapped two HEAVY PSUs at his work and one is for me. However his job is 500km away.

Splendid! About the only information you didn't give was its mass. Lots, I imagine.

Newbie question: I'm considering building this, and my B+ transformer on-hand is good for 360V@160ma.

Can I use less pass tubes? I'm assuming that these are paralleled to allow for Pete's 500ma current requirement.

I have a handful of Chinese 6L6GC's. If I can reduce the number of tubes to say 2 or 3, does anything else need tweaking?

That should work fine. I'm also going to build something along these lines, though probably more like a Heathkit IP-32 on steroids. Note that you'll need other supplies for the screens and for bias. The way the supplies are floated, they need to be separate windings.

I'd love to see someone sell a PCB for one that tops out around 550V. My Heath is only good to 400V. This would Make a great DIY item as these are hard to find new.

I got a commercial one that goes to 1000VDC @ 200MA. Measures volts, current and computes watts. It's got a digital display. Very kool but it kicks out the overload breaker or frys the voltage control pot (5K) randomly. When I get around to it I'll start with replaceing all the caps otherwise it's got too many sand state components for my meager brain. I'll have to get it fixed. I hope it's KVA rated. Like 500VDC at 400MA? That would be nice. It's a piece of medical equipment used in DNA testing or research. I have not been able to find a scheme.
