I saw a nice pair of RCA 55-B! Those are highest quality line amplifier during late 30s, sound quality far beyond Western Electric 106A! Nice collection!
Nice WE amps , I like all the the WE iron, caps, etc…. This is quite an impressive collection of WE gear, so the speaker playing is the WE24 or is it the 26 horn tar filled with a 555, super clean. Awesome sound bet it has incredible room air control
