A while back I was working on this old power supply and had corresponded with someone in Radiomuseum on this. I am back on this project and hope to get some added help. Here is what I know:

The transformer in this unit is putting out 250 (+/-) volts DC. I tested the voltages at the taps and they are all wrong, indicating a bad resistor I think. The 135 VDC tap reads a full 250, the 90 vdc tap also reads 250. The 67 and 22 vdc taps all read low.

I substituted the big Mershon liguid filled cap with three smaller electrolytics rated for 600 vdc. (10uf as indicated on the original).

The resistor resistor reads open all the way up, except there is resistance between the top two (135 & 90) but not to the common below. The posibility of finding a replacement resistor is probably nill. Likewise any schematics.

My goal was to make this a functioning unit again, not just a display.

Can anyone offer some assistance?

Thanks in advance,

Mark
