The TS41 developed by GEMA from the TS4 is a power triode for transmitter use. The anode dissipation is 150 Watts. The mutual conductance of 6.5 mA/V is achieved at 1 kV on the anode and at a current of 300 mA. The filament is thoriated tungsten. In continuous operation the maximum voltage would be 2,000 V and 250 mA anode current. For pulse use the maxima were 8 kV and 5,000 mA per pulse.
The TS41 was used in pulsed mode for radar at a wavelength of 2.5 M. It is reported that in parallel push-pull a bank of six TS41's could generate megawatt pulses.
The oval anode and ceramic spacers - used in view of the EHT involved.
The control grid connection passes directly through the side wall.
The base infill is ceramic and the connection sockets fit standard 4 mm plugs.
Here the thick filament can be seen to make six passes through the wire grid.
A closer view - distorted by the envelope.
The three filament tension springs, showing the loops that hold the thoriated tungsten wire loops.
The ceramic block is fixed to the substantial grid supports.
With a little enhancement the lettering etched in the glass becomes clearer. The last three digits of the serial number are 269. The word above is Wehrmacht - The German Government of the time.
The wide glass tube envelope is 63 mm in diameter, and excluding the base is 194 mm tall.
