SIEMENS E810F
A high transconductance pentode designed for wide band
amplifier applications. It shares the same pinout with the D3a and is also
somewhat comparable to it. It has the same heater voltage of 6.3V and needs a
similar current of 320-360mA. In triode connection it has a bit lower
amplification compared to the D3a but still a high value of 60. It was designed
as 'special quality' tube with a high life time of 10.000 hours. The Siemens
E810F tubes in stock are available in pairs matched as pentodes.
