Replacement Commodore 64 Capacitors

Electrolytic capacitors can dry out and fail, and with retro machines now 30+ years old it's a good idea to replace them before damage occurs.

I have made up replacement capacitor packs for the various C64 motherboard versions (going by the ASSY / REV number printed on the top of the PCB). All caps are good brand, long life types. For ease of fitting, they have the same case style (axial/radial) as the originals.

Please note: The values originally fitted by Commodore can vary slightly (from their own schematics!). Please check the listed contents of the packs against those on your particular board. (Where there is a difference it's normally only a capacitor's rated voltage and that should not matter, but if you require a substitution just leave a note with your order in the Special Instructions box during checkout - or contact me if unsure.)

Restore key mod capacitor - axial type 4.7nf

Restore key mod capacitor for Breadbin C64 - Axial type

  • It has been found that replacing C38 with a 4.7nf capacitor improves the response of the restore key, ie: when modded, pressing RunStop+Restore should respond with the same pressure as any other key.
  • This is an axial type capacitor (wire at each end of cylindrical body, the same as the format originally fitted at C38 in p/n: 250407 boards. (Later boards had a additional pad allowing easier fitting of radial type caps as well as the pads for axial types).It doesn't really matter which type you fit, both are offered in case aesthetics are important.

Restore key mod capacitor -radial disc type 4.7nf

Restore key mod capacitor for Breadbin C64 - radial disc type

  • It has been found that replacing C38 with a 4.7nf capacitor improves the response of the restore key, ie: when modded, pressing RunStop+Restore should respond with the same pressure as any other key.
  • This is an radial type capacitor (both wires emerge from same end of cap). This type of cap was often fitted at C38 in p/n: 250425 boards though these could take axials too. It doesn't really matter which you fit, both are offered here in case aesthetics are important.
