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 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.

Ceramic capacitors do not age in the same way as electrolytics so usually don't need to be replaced, but they are quite fragile and easily damaged.

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.
