The C64 Capacitor Mod Breadbox64 He offers capacitor packs with the correct capacitors for each pcb version already packed and ready for shipment. the following images are from a mod job i did for a friend on an assy 250425 rev.b long board. it can also be done on a commodore 64c board (assy 250469 rev 4). 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.
The C64 Capacitor Mod Breadbox64 Recapping a commodore 64 (all board revisions) restores stable power rails, lowers heat stress on mos chips and cures many “mystery” crashes, video glitches and sid noise. To complete the modification, simply remove capacitors c1, c4, and c5. this will eliminate ghosting and blurriness, though the picture may appear slightly less vibrant and a bit darker, especially via s video. see the pictures below for guidance on which capacitors to remove. My sixtyclone c64 replica has a sweet looking blue printed circuit board (pcb) (link). the same is the case for the installed vic ii² pal ntsc switch (link) which enables swapping the video output of a commodore 64 between pal and ntsc by the flick of a …. Usually just the electrolytic capacitors need to be replaced, especially the larger ones on the right side that provide voltage increase and supply filtering. there's only a few of smaller electrolytic caps left so its wise to replace them while you have the bottom rf shield off.

Our kits ship with 25v caps. * replace the 51pf cap with a 4.7nf cap to restore soft touch restore key function. this is included in our kit. On account of the pressure dependant resistance of the keys, pressing the restore key just as softly as the other keys is not sufficient for producing a trigger signal at the timer's trig input. therefore, we will replace it with a 4.7nf capacitor. the problem described above was fixed in the new pcbs and in the sx 64. Our c64 mainboard capacitor kits do not include replacement capacitors for the rf modulator. you can grab those here. we use only the highest quality capacitors in our kits (rubycon, nichicon or panasonic). for a complete capacitor list and schematic, please visit our support wiki. In workbench wednesdays , one of my mini projects was to replace the capacitors in a commodore 64. in the video, i only had time to replace about half of the decoupling capacitors. later i'll go back and finish the rest. this post discusses why i picked the capacitors used in that project.
