The 45 was first introduced in 1929 and was originally named UX245, then later on different versions were made of the same valve.
The 45 has been put back in production together with the 300B and remains one of the best audio valves. The balloon 45 we have are Arcturus blue glass with flat plate and a pair of RCA balloon
Both tested with full emission and current of 46mA and 45mA for the Arcturus; 44mA and 45mA for the RCA.
Both in excellent shape and working order.
