Beschreibung

This tube was specially designed by the Nutron company and was claimed "to be better by fully 25% of any other tube on the market". The anode area was bigger than the 201A type and the filament longer. They were said to have a mutual conductance of over 900 ohms and an anode impedance of 7000. The amplification factor was 7.5 to 8. This information from the Radio News advertisement of October, 1924
