  • Adzam 6SL7GT
    $70.00 Choose Options Adzam 6SL7GT
    Adzam 6SL7GT - 1950's vintage from Philips Holland. Silver colored plates make them look just as cool as they sound. As with any of the tubes from the Philips Holland factory, has a smooth midband with just a little more top...
  • Brimar CV1985 / 6SL7GT
    $70.00 Choose Options Brimar CV1985 / 6SL7GT
    Brimar 6SL7GT/CV1985 - Made in England, 1950's vintage. Smoother and more lifelike than that Russian stuff. Greater sense of depth. Ever so slightly relaxed on top. Packed in NATO military boxes... so if nothing else you can...
  • RCA VT-229 / 6SL7GT
    $70.00 Choose Options RCA VT-229 / 6SL7GT
    RCA 6SL7GT/VT-229 - 1942 vintage. I found these in Europe. Like the 1944 vintage Sylvanias, these were left there by the U.S. Army after World War II, completely undisturbed in warehouses. The boxes say "Western Electric,"...

    $70.00 Choose Options Sylvania Gold Brand 6SL7GT
    Sylvania Gold Brand 6SL7GT - Very cool, super rare vintage 6SL7s made in the U.S. by Sylvania. After we evacuated most of our bulk tube inventory back in 2002 due to the fire that came very close to our shop, some cool stuff...
  • Sylvania VT-229 / 6SL7GT
    $50.00 Choose Options Sylvania VT-229 / 6SL7GT
    Sylvania 6SL7GT - These were issued to the Army in 1944 and were left in Europe at the end of World War II. Undisturbed for over 50 years in a warehouse until I picked 'em up during a tube hunting trip. Great sounding tube...
  • U.S. Made 5691
    $75.00 Choose Options U.S. Made 5691
    U.S. made 5691/6SL7 - You know the tube. The G.E. and RCA (same tube) 5691 is the most sought after 6SL7 variant. Some are red base, some are brown base, some are black base. They're all the same tube, and we cannot...
