Hey guys,
I'm looking for a dual current limited regulated power supply that can do around +/-100V at about 1.5 to 2A.  More current or voltage is fine, but I don't want to pay for WAY more than I need unless I have to.  I don't need isolation between the channels since I'm using it as a split supply for an amplifier.  It would be cool if it was programmable, but that's not absolutely necessary.  Adjustment knobs are ok.
The best I have come up with so far is this BK model, which only goes up to +/-70V:

Suggestions?

If you can live with 1A up to 120v, get two of these : https://www.circuitspecialists.com/benchtop-power-supply-csi12001x.html

Or get two of these that can do up to 3A : https://www.circuitspecialists.com/bench-power-supply-csi12003x.html

Nice.  That looks like a good cheap solution.  One single unit would probably be preferable to two separate supplies just so I wouldn't have to coordinate turn on and turn off though. 

I'm kind of surprised I can't find a single split supply that has current limiting in that kind of voltage range.

Lambda LPD-424A-FM is a nice dual 0-120V unit that's cheap on eBay, but only 0.38A per side.

That's too funny.  What I'm using now is the 40V, 1A version of that same supply :)   It's a good supply.
Unfortunately I need at least 1A.
