The power supply consists of a full wave disk rectifier and Qty(2) 0.1uF capacitors. The dry disk rectifiers are mounted on the speaker. An output transformer is also mounted on the speaker, which reduces the high input impedance down to a lower impedance needed to drive the speaker. The cable from the output transformer inputs has phone tips used to connect to the output of the receiver.
A recepticle is provided on the rear of the cabinet and can be used to supply AC power to the receiver that is used in conjunction with the speaker. A power switch is mounted on the cabinet, with the switch controlling both the speaker power supply and the ACreceptacle.
