RE: Tungsol Roundplate 6SN7: Why so magical?

Posted by Tre' on July 9, 2020 at 10:18:41:
Are you sure you're not looking at 6sL7s? Almost all of those have round plates.

I have over 100 vintage 6sn7s and the only ones with round plates are the tung sols.

I did find one reference to the "rare" round plate RCA 6sn7.
