Description
You are bidding on a pair of Raytheon type JAN CRP 6SD7GT radio/audio tubes (pentodes) made for the US Military. On my Amplitrex AT-1000 tester, they test strong. One tests at 111% Em and 97% Gm, while the other tube tests at 120 % Em and 100% Gm. So, they are both good strong nearly matched tubes. They are identical with the same date code, 0-36, made in 1950. They have black plates, and come in their original military boxes. These are guaranteed to be good strong new tubes that should make a great pair for your project! Shipping weight is 8 ounces. Please see my other auctions for more interesting tubes, and radio and audio items.
