EL37
EL37 has no equivalent designation confirmed by the archive.
The EL37 is a pentode vacuum tube intended for audio output service, with its datasheet providing operating conditions for two valves in push-pull with self bias.
Operating Conditions
The datasheet gives push-pull operating points for screen grid voltages (Vg2) of 250 V, 325 V, and 350 V. It also lists a screen grid current (Vg3) of 350 mA for push-pull operation. For these conditions, the datasheet specifies a cathode resistor (Rk) of 150 ohms and a load resistance (Ru) of 130 ohms. Input voltage (Vun(rms)) values of 29.0 V and 43.0 V are given, along with maximum anode current (Ia max) values of 2x68 mA and 2x90 mA for push-pull operation.
