More selling of my tube collection. Here're some very nice 6CG7 and 6FQ7 vacuum tubes/valves manufactured by Sylvania.The 6CG7 and 6FQ7 is a very nice tube, and Sylvania designed and manfactured some nice variants of these tubes. Here's what's on offer: - Early-/mid-1960s, "proper" 6CG7. Nifty tube. This is a real 6CG7 with silver plate shields. "Stepped" gray plates with O-getters. - Early-1970s to the end of Sylvania tube production, 6FQ7. As above but without shield and with filament bridge wire. Some are NIB (as far as I can tell), some are used. Some have excellent printing, some none at all. All have been carefully tested on one of my professionally maintained tube testers (Dan Nelson or Roger Kennedy) - a Hickok RD-1575, a Hickok 6000A, Heathkit TT-1, TV-7D/U. Test results and pictures happily provided for the tubes you're interested in. Price? Ranging from $8.00USD to $16.00USD each depending on variant and condition. Negotiation welcomed. Let's chat about what you're interested in. Cheers. - SJ
