Beautiful tube, new in the box (which looks as nice as the tube)! Tests very high on my mutual conductance tester. Ultra fast shipping, too. Can't thank you enough for the honest, fair deal.

Beautiful pair of tubes! Both test very high on my mutual conductance tester. Can't wait to hear them, but that may be a while. Fast shipping, too. Mr. Leeds is the real deal. Thank you!

By far the prettiest of the 6SJ7s (all the rest are metal tubes) I've acquired to prolong the life of a Tweed '54 Fender 5C1 Champ. Sounds great, too.
