| Description |
Car radio class-B push-pull twin output triode.
The EDD11 achieves at low heater power and only 7 mA zero-
signal plate-current and 40 mA at max-signal a
comparatively high output power of 5.5 watts.
Requires -6,3V bias and 0.1 W input power from
the driver tube EBC11.
At its time it was the
sole twin triode in Germany, hence it was also
used for other purposes, e.g. as AF
preamp.
