Description |
Stokes (p.77) says "released early in 1933" and gives a reference (p.81): "Radio Craft, New Tube Developments, Jan.1933, p.398"; If an article is printed in January it most probably reports from the near past, i.e. from late 1932! There was an information, then the report had to be written before printing. Stokes conclusion appears to be inaccurate.
