| Description |
Triode+Output-Tetrode launched early 1939 by Telefunken
Predecessor: ~EL11
Successor: ~ECL113,
The ECL11 is an output tube EL11 completed by a preamp-triode, thus the entire AF-part is accommodated in a single tube. A superhet then may be fitted with the lineup ECH11, EBF11 and ECL11, saving one tube. With exception of Tungsram the ECL11 was always sold as beam-power-tetrode.
