| Descrizione |
A series of Fleming valves were made at an unknown location in the US for the Marconi Wireless Telephone Co. of America. Most of these had B22 bayonet bases and a "flying lead" for the anode.
Dual trapezoidal plate, 33mm tubular American Marconi Fleming valve with a "flying lead" anode connection. While this valve is also very similar to the valve pictured in figure 24 in Tyne's 1943 Radio News chart it must be an earlier variation based on the filament support structure.
Diameter: 33mm
Length: 90-100mm (including top pip-seal and base)
Filament: Inverted V
