Film Filter Caps?

[soapfoot]

Engineering is making sure your resources are allocated in the way that provides the most benefit

If an amp has five large filter caps and I spend $40 on each (as opposed to $8 for an F&T electrolytic), that’s a cost difference between $200 and $40.

I’d want to be absolutely sure those parts were offering an improvement I couldn’t get by spending <$160 elsewhere (better-quality transformer, speaker, tubes, cabinet, etc)

If making a one-off and you have unlimited resources, go nuts! But in most other scenarios, it’s advisable to target spending for maximum benefit

I replaced the cheap chinese film caps in the KT LA2A clones with Solen. It made a surprisingly big audible difference. That said, WIMA polypropylene would work similarly well.
