I have this 9 years old GDS 2102 scope, with a faulty power supply.
I'vr discovered (did not remember) that the PS is always connected to mains, the rear switch is for optional battery operation.
I've checked major parts, replaced a shorted MOSFET in the primary side, a broken NTC and open fuses, but no results: new fuses do not burn, a loud thump (
) but no smoke or flames, power supply dead.
Need a more accurate examination-
Does anybody have a schematic or a service manual, or a source for a spare?
Thank you for any help-
Best regards
