Commodore A520 RF modulator
Commodore A590 and clone (for example ROCTEC) external memory expander, hard drive controller
Commodore Amiga tank mouse
Commodore 1403/1405/1407/1428/1428/1428X/1432D/1432V/1930 VGA displays

Commodore Ranger 15/Ranger 21 VGA displays
Commodore clone (for example ESCOM) VGA displays
Commodore 1010/1011/1411 and clone (for example ZYDEC, AMITECH, AF) external floppy drive
Commodore Amiga internal floppy drive
Commodore Amiga power-supply
we do not undertake these:
Repair of Commodore Amiga turbo cards, internal IC memory expanders.
Repair of original Commodore Amiga CD32 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.
Internal/external FDD repair.
We tried to fix them before, the result was that they worked for a while and then not again. Therefore, FDDs are replaced by modified PC FDD sor GOTEKs.

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
- AGA PCB trace and board repair, replacement, re-tinning remaining tin surface
- cleaning contacts
- in case of drivers: cleaning, replacing electrolytic capacitor (Re-Cap) with a shape-correct version (axial/radial), oiling, replacing the belt, resetting head (with fixing)
- checking current consumption on PCB
- running DiagROM, 30-minute software testing
- replacing keyboard foil (with a tested type)
- erplacing rubber feet on covers (shape- and color-correct)
In case of power-supplies:
- loadability test
- replacing electrolytic capacitor (Re-Cap) with a shape-correct version (axial/radial), in secondary and bypass areas with LowESR types
- correcting output, protection and starting voltages
- replacing damaged terminals (230V AC, and low voltage)
