Up for sale, a pair (2) used Sylvania 6SN7 GT tubes, made in US. Both test well on my calibrated Hickok 539C tester and Fluke VOM. Identical in shape, shiny black plates. They test fairly close and balanced. Codes the same 639, which I believe indicates 1956 manufacture.
These are similar to the so-called "Bad Boy" tubes, and they really are excellent.
They were tested in circuit and heard no bad noises or microphonic. I got these for a preamp project that never materialized.
Test measurements below:Tube #1: 3200 gm. (1900 min)
3300 Tube #2: 3100 gm.
3200 Both 7.2 - 8.1 mA current.
Will be well-packed in bubble-wrap and sturdy box. Shipped within US for $4 more, US Postal. More for overseas shipping.
Buyer will receive 2 tubes, as shown. Asking $69.
Thanks for looking.
-Pete
