HP 6236B power supply
(1/1)
BeBuLamar:
Got one yesterday from the estate sales for $20. It had a couple of problems and I fixed it. A very well built unit but it's quite limited.
Stray Electron:
I'm not sure what you mean by quite limited. But IMO that's a great find for $20 and those are very useful PSUs, particularly with OP amp circuits where you need multiple voltages and +/- voltages. And being made by HP, they're built to last forever and you can get FULL service information and all of the parts for them. The only downside to them is that they're transformer based so they are bigger and heavier than the switcher type PSUs but that also means that there is a lot less electrical noise in the outputs and less radiated RF noise.
What's the date code on that PSU?
FYI, the caps used by HP seem to hold up very well so don't go in there and just start randomly replacing capacitors!
BeBuLamar:
Limited because for the 0-20V only 500mA. I wish it's more like 3A and 30V. The 6V and 2.5A is good and it's also adjustable. Many other PSU there is only a fixed 5V. I don't mind it's transformer based because it would have low noise.
J-R:
$20 for some fun tinkering on 50 year old gear. But there is no adjustable current limit and only one output can be monitored at a time.
