it is always a good idea to replace pots rather than cleaning them unless the pots are not avialable and I could understand that. I am glad it was back to life and as always, good job and keep up the good work. have a blessed day and thanks for sharing.

I had a power supply that gave me trouble diagnosing it .... There was a bad transistor that I replaced and still no go .... I checked everything that could go wrong , there was a zener diode that was in the circuit with the bad transistor . It checked good on 2 testers , I changed the zener and the power supply came back to life .... I saved the old diode and brought it to a friend that had a Curve tracer .... You guessed it , that zener was leaky , AKA breaking down under power , the little component tester and multimeter couldn't put a big enough load on it .... So it was time to build a homemade octopus that hooked to my O-scope to turn it into a curve tracer ...

These V-guard devices are still very uncommon in my country. We probably don't need those here at our stable AC 230 voltages.
And devices like our 3D printers these days have their very unique Power-Outage-protection build in its firmware to protect losing almost completely finished 3d printed objects, that took hours to print, after a sudden power loss. Because as soon as the Power is back on the 3D printer follows were it left off with the help of the on the internal SD card recorded object code that saved the exact gcode position until the moment the Power loss ocurred.
Something that also would be very helpful when burning Bluray or DVD discs that often also take long and would be wasted after a Power loss.
