I've been doing some reading on replacing the multi-section can-type caps in my old amp. They're hard to find FP types and I've been unable to locate exact matches. Vibroworld.com offers to build new cans to whatever specs you send but I don't really see the rationale for keeping the can-types when I could just replace them with the appropriate number and type of modern electrolytics. For all intent and purpose, custom-made cans just feature small electrolytics crammed up in the can, right? Does anyone have an opinion one way or the other?
