Man, THAT is a rectifier! Sure would look good in a set up with a couple of 250TH's.



You would do better with a pair of 575A's or 872's. That high vacuum rectifier will handle a lot of voltage, but look at the voltage drop at 500 ma.

The tube would be useful for something over 10 kv and fairly low current. The filament consumes a lot of power as well.


The 2-2000 falls into the same catagory.

I remember, Don, on one of my 'treasure hunts' at John Mohn's/W5MEU, that he had a regulated power supply, using a pair of 4-400's. I'd sure like to know more about using tubes, especially those high-power pentodes, as voltage regulators.
