we do not undertake these
Repair of original Commodore C64, Plus 4, 1541-II and 1581 power-supplies.
Unfortunately, the factory power-supplies are molded in their casing, so it is impossible or quite circumstantial to repair them, so we cannot undertake their reparation.

good to know
During repair/restoration, basic service for all devices (if not already done):
- replacing electrolytic capacitor (Re-Cap) with a shape-correct version (axial/radial)
- chemical washing of PCB, casing and keyboard
- neutralizing leaked electrolytic liquid on PCB, removing resin stains (even after repair)
- microscopic checking parts and solderings, replacement and repair as needed
- replacing loose, damaged IC parts and rusty, rotten parts
- cleaning contacts
- in case of drives: cleaning, replacing (axial/radial) electrolytic capacitor (Re-Cap), oiling, replacing belt, reseting head (with fixing)
- checking current consumption on PCB
- running Hardware Test, 30 minute software testing
- replacing rubber feet on cover (by shape and colour)
In case of power-supplies:
- loadability test
- replacing damaged terminals (230V AC, and low voltage)
types I have repaired:
MOD: modifying Commodore 64 NTSC to PAL
With the modification, in addition to the VIC and crystal, the RF modulator also needs to be replaced. Of course, it’s not important to replace the RF modulator if you only use the computer with a Video display.
MOD: installing Commodore 64 RESET
It’s not a HW reset, just a software reset, but it’s also good for turning on the switch less. Quite a few switch go wrong nowadays, but with this, we spare them as much as we can.
