Connecting a 3W1 Wallbox to a Sinfonola2000

Hi,

I just got a 3w1 Seeburg Wallbox, and I intend to connect it to my Sinfonola 2000 Jukebox. This blog can be useful for someone with the same idea.

THE JUKEBOX

The Sinfonola 2000 is a copy of a Rock-ola 443 (100 selections mechanism) made in Spain by Gedasa. I believe that Rock-ola licensed to this Spanish manufacturer the patents for his mechanism and Gedasa produced their own Rock-ola under the name of GEDASA. If someone has more information about the history I would appreciate knowing.

There are minor differences between the Rock-Ola and the Sinfonola: The amplifier is completely different and the keyboard is also connected differently, but most of the parts are interchangeable (I replaced some parts of the turntable, the gripper motor, and the coils that make the selection in the wobble plate with original Rock-ola, and all fit like a glove). Also the external layout of the machine is slightly different. Being the shape of the machine the same, the title cards are located over the front speakers in the Gedasa and the selection keys are higher.

The Sinfonola2000 is ugly (sorry, but facts are facts. The Rock-ola 443 is also not a handsome machine. None of them are a match to a Tempo) and bulky. This is the reason I decided to hide it in a corner and put the wallbox in a more visible place.  

THE WALLBOX

The Seeburg 3w1 gets it’s name from the fact that only uses 3 wires to get connected to the Jukebox (one is ground, the others are mains at 24 alternate and signal). It has 100 selections and the shape that anyone would recognize as the right shape for a wallbox.

In the next days I will write more information on how the wallbox works and how I am progressing with the connection.
