EKA ABC Super Five Tube Radio 1936 Vintage Restoration Data Schematic Page 2

The power transformer made with taps for all the many differing line voltages of the time, from 100 VAC to 240 VAC at 50 Hz. The set used a full wave rectifier using the standard AZ1 dual diode power rectifier tube. The AK2 converter followed by the AF3 IF amplifier stage and the DS4100E tube worked as a demodulator and audio preamplifier. The audio amlifier stage used the powerful AL1. This set, as many others at the time, used the speaker magnet coil - marked with a G on the schematic as a power supply filter coil.
