Help: Does anyone know how many JBL SA600s were manufactured?

[Proczak]

I came across a gem 1 owner, all original parts, still in mint working condition. Do you know how many were originally produced when it came out in 1966? I would really appreciate an answer as JBL does not have the records. 71400

I have no idea of the production numbers. I can tell you that the industrial design (appearance) was the work of Arnold Wolf, consultant to JBL for years and (later) JBL President for a while. Search this site for more info on him. Prior to this he had done industrial design for the Sargent Rayment line of electronics. Research these for similar design themes.

The circuit design was (AFAIK) the work of Bart Locanthi, featuring his then-novel, later commonplace T-circuit output stage design.
