Clear plex housing with three internal bays. One for batteries, one for signal processing electronics, and one for tuning capacitors. On-off toggle switch on top next to rotary volume control and two bridges. Large tuning knob also on top. There is no internal speaker but rather a two-pin connector on back side of radio along with three bridges and holes to allow adjustment of capacitors. Four holes on front of radio allow adjustment of electronics. Paper label: "Batt. Inst. 1969" and small calendar sheet for Nov. 1969 with the 18th circled. Two Eveready "radio A" batteries (#724) powered the unit. References: Arthur P. Stern and John A. A.
