Description: You are bidding on a pair of type 6B4G radio/audio amplifier tubes. One is a branded RCA, and the other is branded General Electric. I normally encounter these black glass variety branded National Union, so they may be the manufacturer. On my Amplitrex AT1000 tester, they test as new, the RCA at 102% of the specifications for a new tube for emission, Em, and 99% for mutual conductance, Gm. The GE tube tests at 91% Em and 100% Gm. So, they have seen very little use, and should make a great pair for your amplifier or radio. Shipping weight is 13 ounces. Please see my other auctions for more interesting radio items and tubes.
