power supply?  Seems it was used in a medical application.

Just to follow up on the weird turn this thread took. The Original poster decided not to buy the supply, BUT he mentioned another _TWO_ he had seen in my Neck of the woods.

They arrived today, and from a first glance look like very competent little supplies. (have not tried to power them up yet.)

Both the voltage and current seem to be on ten turn dials. My guess is that the "negative resistance" of a nixie tube would give them fits if used without a limiting resistor. The output seems to be the sort of Double insulated banana plugs the modern Voltmeters use.

Without a manual I will have to approch these guys with caution, but they look like a good higher spec companion to my old STARK bench supply.
