The ones I own are Heathkit IP-2717s. They output 400 VDC at 100 mA maximum, and both 
6.3 and 12.6 volts for filaments.

In addition, they have a variable regulated bias output of up to 100 VDC at 1 ma.

The supplies are very useful around the tube-based ham shack.

I have something like 8 of them left. I had to rebuild several of them. They were surplused 
by the University of Idaho some time back. I got them all for $5.00 each.
