Title: S.E.X. 3.0 - 220uf 250v Electrolytic caps upgrade
Post by: roycruz23 on March 04, 2019, 04:01:22 PM

Hi! I plan to upgrade 220uf 250v with NOS ROE caps (see picture)
Please let me know if this is appropriate. Thanks!

I've pulled a lot of those out of vintage gear where they have failed.  New production electrolytics are far superior to the old stock stuff, but it's your amp, so do what makes you happy.

I notice that the case is uninsulated and serves as the negative electrode. Only one of the two caps is grounded, so you will have to take care with mounting to prevent short circuits or accidental contact when measuring voltages!

I would wear suitable ear protection before powering those up... honestly its a fools errand as the caps supplied are far superior.
