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.)

Capacitors for C64 TV modulators

Capacitors for re-capping the C64(c) modulator.

The C64's modulator can be thought of as a single replaceable unit but it is possible to open it up and replace the capacitors if desired. I have simplified all the previously available modulator packs into one universal kit which covers modulator types  MD6-VA3403, MD6-UE3603, 251025-x, 251697-02 and 251916-03A. Other variations exist, if your modulator has a different part number to those previously mentioned please check its components before ordering.

Contents:

  • 1 x 470uf 10v (MD6-UE3603 AND MD6-VA3403)
  • 1 x 330uf 10v (25169-02)
  • 1 x 220uf 10v (251916-03A)
  • 2 x 100uf 16v (One in all types except MD6-UE3603 which has two)
  • 1 x 10uf 16v (All types)

Note: The voltage rating on the original caps varies - those above marked as 10v may be 7.5v, 10v or 16v in your modulator. This is irrelevant - the voltage used in the modulator is only 5v, so anything above that will be fine.

Restore key mod capacitor 4.7nf

Restore key mod capacitor for Breadbin C64

  • It has been found that replacing C38 with a 4.7nf capacitor improves the response of the restore key.
  • EG: When modded, pressing RunStop+Restore should respond with the same pressure as any other key.
