Pair, Sylvania Type 45 Radio/Audio Amplifier Tubes, Amplitrex Strong
Item History & Price
You are bidding on a pair of Sylvania type 45 ST shaped radio amplifier tubes with printed bases. On my Amplitrex AT1000 tester, one tests at 101%emission, and 105% Gm, while the other tests at 94% Em and 103% Gm. So both are good strong tubes with high grid emission that test as new. Theyare nearly identical tubes with the same internal structure and black plates, but the date codes are different, 152, and Z3R. These are the same as the earlier Cunnin...gham CX 345, or RCA Radiotron type UX 245tubes. They are guaranteed to be strong matched tubes that should make a great sounding pair! Shipping weight is 8 ounces. Please see my other auctions for moreinteresting tubes and radio and audio items.
