ESS Tempest LS8 crossover caps

[eizner23]

I am restoring a pair of ESS LS-8 Tempest 2-way speakers with Heil AirMotion tweeters. Looking at the crossover, i see high quality 19uF and 7.5uF film caps but no tolerance values marked. Being manufactured in the late 70's, would if be worth updating to fresh film caps?

I don't think those are film caps, despite their appearance... yes, it's worth updating. If you want a brighter sound, I recommend Solen caps. If not, there are others out there as well, but I am not as qualified to answer as I have my best experiences with those caps.

Back in the day,those were referred to as "computer grade" caps. They're not good . Change them.
