This Catalog No. 3621 AKA 350 Preamp was built in 1953, I bought it from the original owner of an advertising Co. in 1975 when they upgraded and I was servicing there electronics, I used the Ampex 403 Deck till 1980 and retired the transport and moved the preamp to my recording rack.
Most ppl that are selling these cheap and untested with out the power supply from $1100.00 to $1500.00, Mine comes with a recent recapped power supply and the transport if someone would want to restore it.
The preamp sounds very lush with all my microphones especially the RCA 44 ribbon mic, no noise hum or pops from the preamp and the tubes are all excellent with no microphonics
