Default FS PA02 Power op-amps +/- 18v, 5 amps

I've had these sitting around for a number of years (10?). They were left-overs from a project a friend of mine did for the military. Most are brand new though some have been pulled from equipment (they were socketed) and by now I don't know which are which.

Basic specs:

HIGH POWER BANDWIDTH - 350kHz
HIGH SLEW RATE - 20V/s
FAST SETTLING TIME - 600ns
LOW CROSSOVER DISTORTION - CLASS A/B
LOW INTERNAL LOSSES - 1.2V @ 2A
HIGH OUTPUT CURRENT - 5A
LOW INPUT BIAS CURRENT - FET INPUT
ISOLATED CASE - 300VDC

They're pretty cool devices and you can find more information on them here:

I've used some for audio amps, driving small motors, even played with two as an adjustable +/- power supply back when I did more audio stuff.

Apex wants $58 each for these bad boys, so how about $8 each? I think I have about 30 of these, I'll have to check. I have a few sockets too, handy since it's a little tough to find 8-pin TO-3 connectors.

I'll guarantee them not to be DOA. If you want I'll try to dig up an old audio amp I had and test them before shipping, but that may take me a week or so.

Any interest?
