    Looking for information on the above supply, have 2 that I haven’t used in years and want to get them cleaned up and back in use.

    Thanks,

    John

    They seem like simple linear supplies - nothing unusual - do you know if they work? How about some pics?

    If anything, checking the major components (smoothing, rectification and regulation) should be enough to ensure it switches on without spectacular fireworks! If you want to be thorough then testing for regulation, ripple, noise, transient operation and adjusting calibration would cover most things. Not sure you need any technical data to do all this though.

    Would be nice to know regulation and ripple specs, also hookup for the sense inputs, output range adjustments. Did have that stuff years ago, but too many moves since then.
