I’m rebuilding a CA-1000 integrated amp I just purchased, and am having trouble tracking down replacements for the main power supply caps. The originals are 18,000uF 63V and are 50mm diameter and 80mm long, and there’s not room to fit larger ones in the amp. They also have solder tabs soldered into a PCB, although I think I could make snap in caps work. Neither Mouser nor Digikey have a cap which will physically fit and meets these ratings. The closest I’ve found is a Nichicon “Super Through” from Parts Connexion, which is an exact physical fit (including the solder tabs) and 63V, but only 10,000uF. This is Nichicon’s top of the line power supply cap. Would the quality of the cap make up for the lower capacitance? I usually listen at low to moderate levels, and expect to use Class A mode a lot. Parts Connexion also has some Mundorf caps at 22,000uF 63V which are physically a bit smaller than the stock ones. Would those be a better choice? Should I expect those to be as reliable as a Nichicon? Any other suggestions? Thanks!
