Two tubes are visible, a 6X5 and 6V6. The signal is transmitted over
the power lines to the receiver in the jukebox.
All you have to do is plug in the wall box in a power outlet in the
same circuit as the jukebox and make your selections. In the past wall boxes
were a great money maker. Most patrons made the same selections and the
record was played only once..
A wall box was mounted near each table in many restaurants. Patrons made
their selections while seated at their table. In a time that one play was 5C
only, each could easily bring in 25C to 50C.
The red chassis is the stepper & wireless receiver, here built in a Wurlitzer
1100. The audio amplifier is visible above. Everything is covered with dust..
The sensitivity of the wireless
receiver can be adjusted. While doing this a tuning eye can be inserted in the
receiver. After all equipment is set up properly selections can be made from
any place where a wireless wallbox is plugged in.
No more wiring needed!
