Philips EBL1 Double Diode Pentode Power Output Tube.
Europe side Contact P8A
The EBL1 is an EL3 extended by two signal diodes. It was used in simple
superhets without audio pre stage where the output section was directly driven
from the diode detector, or in sets where the audio pre stage was combined with
the IF stage (6F7, ECF1, ECH4) or with the tuning eye (EFM1, C/EM2) or also
used in the 3-diode-circuit combined with the EBC3.
