Years ago I used this a lot when I had a Windows computer. I switched to Mac and so of course have not used PSUD since. Now I have access to a Windows machine and have loaded the program, seems to work really well apart from one major problem. I seem to get about twice the voltage you might reasonably expect. For example I have a 620 volt CT transformer into CLCLC filter, using 5AR4 in a full wave and I get about 840 volts output. What am I doing wrong? TIA
Follow Ups:
Are you loading 310 volts or 620 volts?
For a CT transformer with rectifier tube, full wave, the program expects you to input half the end to end secondary voltage.

I was putting in 620. Thanks!
Likewise, for winding resistance, use half the total (CT to end).
Whoops, what I wrote earlier is for a full wave bridge.With half wave and single rectifier and capacitor input, the Vpeak is also 1.4 x V AC.
With full wave and two rectifiers using the centre tap and capacitor input, then Vpeak is 0.71 x V AC. This should be your case.

A full wave capacitor input supply will output Vpeak = 1.41 x VAC. A full wave choke input supply will output Vpeak = 0.90 xVAC. This will vary a bit depending on rectifier losses and transformer load.
So in your case with capacitor input, the output seems about right.
