I try very hard to match physical size and since, as has been noted, that usually means higher working voltage, it's not a negative. If you're preserving something as an historical artifact, be sure to document what you've done! Otherwise, someone will be really confused 10-20 years from now

Hi folks, Looking at the PSU of my Lisa's ProFile after it died gracefully not so long back and it obviously needs new caps since one of the 1000uF 16V ones has bulged badly. While I'm replacing that one I'll do the 47uF 250V ones too. And the mains filters but I've got a stock of spares for them
