Like tuberist I tried a lot of 6sn7 tubes. My favorites were the metal based Sylvania’s stamped USN. I now use 6f8g and BL 63 tubes instead of the 6sn7’s because I like the sound a little better and the old 6f8g tubes from the 40’s are a lot cheaper then the 6sn7 of the same vintage. With easily obtainable adapters they are drop in replacements for the 6sn7. My favorites are the BL 63 tubes but you have to be careful using them as they require a little more current and might cause problems to some gear. As always shkong78 I look forward to reading about your findings.
Shootout of Nos 6sn7 tubes
I will have shootout between TS BGRP, RCA vt231, KR vt231, Syl vt231, Raytheon vt 231 and "Bad boy" next weekend.
If I get MELZ 6N8S 6SN7 Metal Base next week, then I will also include it in shootout

"Still harry after all these years" will be for fusion jazz.
Any more suggestion gentlemen and ladies.
