Extras ▼

 

The EAB1 is a triple diode designed for signal detection, ACG rectification and delaying the start of the AGC action in all mains sets with heaters in parallel.
The AAB1 differs in having a 4 Volt 0.64 Amp heater. And the PAB1 designed for series heater chains has a 300 mA heater and draws that current at 6.3 Volts.
