  CN376 is the export version with C20 changed from 32uF to 16uF.

  Chassis can be live (no isolation), for safety C2 and C1 (Aerial and Earth isolation capacitors should be changed to 1kV or 2kV 470pF ceramic safety types). The metal case is isolated from chassis, but Vidor recommended a 3 core lead earthing the case.

  R&TVS claims release in 1949, but Trader lists price and release as November 1948.

  It's not listed in the 1946 to 1952 sections of later versions of R&TVS.
