Ray Tubes 2A3 Select vacuum tube

The 2A3 was introduced by RCA in the 1930s for use in large radios, public address systems, and early hi-fi setups. Despite its notoriously complex filament, the 2A3 saw widespread use in military applications and in the post-war high-fi boom. It was also a favourite of Paul Klipsch, who in 1946 invented his namesake Klipschorn loudspeaker.
