Hello all
Recently blow up my MP-3086 benchtop powersupply i bought from jaycar, due to back emf from a tesla coil.
It normally has a max output of 31v 3amp, but now it stays at like 50v but no current flow. (2n3055 transistor has been replaced and same goes with shunt regulator aswell as lm358 ic and UA741CN ic)
would anyone have a schematic diagram for board model number AQD7.820.501
or even if you have this powersupply could you state the resistor value for r17(show in picture above blue pot), or even take a photo of your board and share it.
Thank-you
Jordan
