Check the LM723 Regulator IC...it's 14 pins and regulates and adjusts the reference to the pass transistors http://www.eserviceinfo.com/downloadsm/21059/Pyramid_PS-36KX.html

This is alink to the p s 3 6 which is very similar to the PS-35

you have specialist equipment, i recommend it is sent to a specials for calibration.
i could be that the warning is somehow connetied and calibration will ensure that what you dial is exactly was is being supplied.

also this model most likely has cooling and that may be getting blocked check that any air intakes and filters are clean and clear to ensure good airflow if the device is getting hot it may cause the warning light to go on.

also ensure the lines are not shorting anywhere.

I hope this was helpful.

Normally its takes a moment for the power to drain when you turn it off, Electronic items with small LED light take a few seconds to go out.

Sin 0 = 0
Sin 90 = 1
Sin 180 = 0
Sin 270 = -1
Sin 360 = Sin 0 = 0

Is there an angle greater than 360???
Is there any greater value of Sine than 1 ???

Sounds like your filter capacitors are bad or weak and some 60hz ripple is getting through. If you have an oscilloscope, check the output to see if there is any ripple voltage.

Buy a heavier duty unit.

yes right there is a short circuit in power supply if you are non technical then replace the power supply if you are technical then open the power supply and check the 4diodes of bridge if faulty replace it again check transistor attatched to heat sink if faulty repalce it

One of your power transistors might have gone short circuit, You will have to have them repaced.

THE BEEPS INDICATE THAT THE OVERVOLTAGE PROTECTION IS ACTIVATED,DO NOT HOOK UP ANY THING TO THAT POWER SUPPLY!!!OR THE FULL UNREGULATED VOLTAGE (20-30 VOLTS)WILL PASS FROM THE SHORTED REGULATOR TRANSISTORS TRHU YOUR GALAXY AND FRY IT.GET IT TESTED BY A PRO,USUALLY THE REPLACEMENT PARTS FOR POWER SUPPLY ARE DIRT CHEAP.
GOOD LUCK.

Check all transistors that are atached to
heat sinks , For a short between two of the
three legs. It can't be reset becuse you have
a short.
