| Description |
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 pear shaped American Marconi Fleming valve with a "flying lead" anode connection. While this valve is very similar to the valve pictured in figure 23 in Tyne's 1943 Radio News chart it must be a later variation based on the improved filament support structure.
Diameter: 33mm
Length: 90-100mm (excluding top pip-seal and base)
Filament: Inverted V
