Hoeffer HV power supplies (two for sale)
0 - 500 VDC variable current and voltage adjustment controls.
200 watts max. Used for electrophoresis work.
these are great for playing around with tube circuits.

$75.00 USD ea.

10 Amp variac Powerstat brand $50.00

Thanks

Can it take 220V in? Or 110V only?

I think it is 110 VAC only although I have not opened the unit to see if other taps are available.
I wonder what effect that applying 220 would have other than rendering the dial indications innacurrate
