First year 1932 Tube leaflet collection E.Erb Analysis by original leaflets

Base Europe 5-Pin (O5A, B5) (Codex=Foo)
Filament Vf 4 Volts / If 0.25 Ampere / Direct / Parallel, (AC/DC)
Description

The original C443 had an amplification factor of 43, the C453 had an amplification factor of 53. When an amateur in 1932 replaced a good C443 for the new C453 in order to enhance performance of his radio, nothing changed. When he scratched some paint of the top of his new C453, he saw C443 appear. There was a lot of fuss about this matter. At the end Philips apologized for redesignating a batch of C443 into C453. As for defence they stated that the C443 was that much improved, that it in fact became a new type, the C453. There was also a similar case with redesignated 506's into 1823.

Excusez l'erreur de sigle 

Selon les caractéristiques données par Philips, les tubes C443 et C443N sont différents, mais les tubes C443 et C453 sont électroniquement rigoureusement identiques avec une amplification de 60. La différence vient peut-être dans leur construction.
