There is clearly some interest in high voltage PSU's like this, a similarly bulky twin 500V Solartron supply made over £700 in February, it was complete but not tested, the two supplies had switches for operation in series or parallel or separately. A single version with lower current capability made over £200.

I seem to remember a valveless HP 712B power supply got offered on here some years ago, I hope it got restored.

My Farnell E350 & HP 711A power supplies get used regularly for testing parts of other equipment I'm repairing.
