I'm going through some stuff I have to move (retiring in June) and trying to decide what to keep. I have a Burr Brown 501 dual supply that puts out +/-15 volts with 115 VAC in. The supply is working but I don't know what's its use was originally. It's a compact block and it's heavy, but there's no current rating listed and I haven't been able to find out anything about it. Is it supposed to supply a reference for calibrating meters or is it used as a power supply? Not being adjustable I wonder if

from 100 to 150 VAC.It's just a supply aimed at permanent installation
in analog circuits.
If it's got air holes, (or you can crack the case)
you might see an internal preset pot or two -
one to adjust output (11-16V)
and one for balance -
sometimes a current limit adjustment.
It might have some value as an antique.

No ventilation of any kind - just small and heavy - which is why I thought it might be used for a micro current reference source. It is pretty tightly regulated even with no load other than the meter as it reads 15.01 (Fluke 177) and doesn't change
I guess I can put a one amp load on it and see if it gets hot or fails...
Thanks for the reply.

I think you'll find it's both low drift and quiet, but
it's getting past it's due date w/r to low frequency
electrolytic filter caps . . . and even film caps.
<<< Given that it's sealed, I figured it's all film caps (although I certainly am not sure), but good quality film caps have never had an expiration date in the ones I've run across the last 50 years or so.
I suggested antique value after spotting one on ebay
for $$$.
Yeah, I saw that LOL, but as I always said when comes to ebay - "askin' ain't the same as gettin'"
It's small enough where it won't be a burden to store it for a while, so I'll not pitch it out yet.
