Hi
Does anyone have a schematic for a Khron-Hite UHR-220 tube power supply?
It works for about 10 minutes, then the voltage rises to about 250 V, and still varies.
I suspect the regulation feedback is opening somewhere and it's running full tilt.
I'm tired of poking around the multitude of components, testing the tubes, and resoldering what I can get at.
Thanks,
Bob

This is a duplicate thread. I posted a response to the same thread in the Equipment&Tools forum.

Emailed Khron-Hite, and sales found the last manual they had and emailed it to me as a PDF. No charge.
That's what I call a great company.
If anyone would like it, let me know.
