Up for sale is a variety of tubes that I purchased in the last couple of months and have barely used:
Sylvania 6SN7W Short Bottle US Navy Tubes:
You are looking at a matched pair of Sylvania 1940-s production short glass JAN-6SN7W tubes. This is simply one of the best 6SN7 variants with wide bandwidth, well balanced, long life, and sounds fantastic. The tube has excellent low level detail resolution, very immediate sounding with a lot of Slam. This pair was purchased used and the seller tested them on a TV-7B/U tester with excellent readings: 102 & 100 and 100 & 100, above NOS standards. Minimum reading for this tube tester is 50 & 50. One of the tubes has a very slight rattle when shook, but this doesn't affect sonic performance at all once placed in an amp. I have put about 20 hours on these tubes.
I am selling this pair for $SOLD including Paypal and shipping fees.
Ken Rad VT-231 (JAN-CKR-6SN7-GT) US Navy Tubes
This is one of the nicest 6sn7's that I have come to listen to, with amazing midrange and best bass I have heard from a 6SN7. They are the highly desirable black coated Ken-Rads from 1944. These are in wonderful condition! There is only the slightest signs of easy use indicated on the top glass. I got them as true NOS and put 100 hours on them. Being military spec and made during the highest standards for WW 2 production, these have tremendous life left in them.

RCA VT-231 (CRC-6SN7-GT) US Navy Tubes
This is a pair of RCA 6SN7GT VT-231 tubes. They have black plates, a rich harmonic structure, beautiful timbre and voicing, and wide soundstage. I purchased them used from a seller who tested them as 97/108 & 108/110 on his B&K 707 Tube tester. I have put an additional 5 hours on them since purchase. One of the tubes has a very slight rattle when shook, but this doesn't affect sonic performance at all once placed in an amp.
I am selling this pair of tubes for $SOLD including shipping and Paypal fees.
General Electric 6SN7 GTA
This pair of tubes came with my Woo Audio 5 amp and have been used about 50 hours at the most. This is a great driver tube, it's fast, has wide bandwidth, and has a smooth sound.
