any suggestion as to what raw DC input, and output mA setting that I should try for VT-25A for this exercise please ??
See post #2061 for the guide, where Salas describes the procedure for figuring out what power requirements are needed for a given target load - so you need to know at least what your requirements are.

Please do take extreme care when working with and using this regulator and any high voltage. One touch with your body parts in the right (or wrong) place can be fatal. I recommend to always use a variac when working with HV supplies, which allows you to bring up AC slowly to ensure you have connected everything correctly.
Or use valve rectifiers as I do.
I think you misunderstood. When I said "working with..." I meant experimenting, tinkering or testing. Nothing to do with known differences between solid state or tube rectifiers.
I said because tube rectifiers have slow start up....
AFAIK, besides slow start up, they also have lower switching noise.
Once used tubes rectification never come back....to SS
Hmmm...strange. I went the other way....after the Cree Zero recovery diodes, Blackgate caps and Salas shunt, it's all heaven. But the valve rectifier is still a great sound. Anyhow, kinda off topic, and perhaps we should leave it at that...? PM me if you want to keep on same note...thanks!
Now?
If I like to try using 12-25mA, do I need to change any component please??
Will need sink for Q1 or Q2 please??
