This is a PAIR (2) of Vintage SYLVANIA JAN CHS 6SL7WGT (VT-229) tubes. These are highly regarded preamp tubes. 

They are marked "Made in USA" on the brown bases. They have clear glass, short black plates without holes, and a top-mounted square getter. Both tubes were tested on my TV-3B/U tester and are strong with tests of 1750/1650gm and 1850/1650. Both scores are well above the tester's minimum of 1000 for a good tube.

I warrant these tubes to be as described when you receive them. There is no additional warranty.

Check my feedback. I describe accurately, pack safely, and ship quickly.
