Question about Sprague Vitamin Q

Posted by SuperB on January 28, 2025 at 05:22:52:

Hello!
My friend has some Sprague Vitamin Q looks like the attached photo. But in different value and ratings, what I will get is 2.5uf 330vac, and 2" in diameter and 2" tall.

He will give it to me for coupling application in tube preamp.

I'm curious how it sounds. Done says it sounds like old Conrad Johnson gears but more mellow and transparent.

Any comments?
