Diode (NOT rectifier) ·Diode-Diode
European duodiode with separate cathodes intended for detector and rectifier functions in receiving equipment.
EB4 is listed in the supplied valve table as a duodiode with separate cathodes. Published operating and characteristic values were transcribed from its target row.
European 5-pin base
General specifications
Properties common to every published source and operating point.
Electrical assignments shared by every tube using this base designation.
No verified pinout is recorded for this base designation.
2 physical sections, each with unique specifications.
Section 1
