I’ve acquired a Krohn-Hite UHR-220 high voltage power supply. Thanks Ross!
I really like the styling on these old Krohn-Hites.
The Jones socket offers the same voltages as the binding posts on the front panel. Handy!
Restoring this will be fun.
I found a scan of the manual, thanks to Dave Riddle (DRCO on eBay). I’ve put a copy in my manual archive; I hope Dave doesn’t mind.
