Help finding raplacement PSU for GS galvos.
I have a feeling that the powersupply in my cheap, (but beloved) single brick RGB PJ have problems. I`m not depply into electronics, and having problems finding the correct replacement PSU. The Galvos are from Goldenstar Lasers. Some of you have probably gotten the 25k set from them due to the low price. For six tendollar bills, i have found the value for money more than good for bulding a beam-machine.
The problem:
When powering up the PJ, the Galvos start clicking, and moves randomly. The red LED`s on both galvo controllers in the same clicking rate, and actually also the led inside the PSU.
When hooking off the Y side, and powering up, i get a nice line, and the galvo sounds normal.
I also got the "not so good" smell of burned electronics, but have not been able to locate from where yet.
I have taken all major components apart to eliminate grounding issues.
But, i`m suspecting the powersupply to be the problem. The powersupply have written on it +15V -15V and GND.
A tip on what to search for would be highly apreciated.
