Initial Teardown

A few weeks back I decided to try and get the RO running completely, but since fate (and bad tubes) conspired against me, I spent the time doing a minor tear-down instead


As purchased, the jukebox has a spinning platter, and the magazine assembly will rotate when manually triggered via the "load" switch located inside the front door, but it won't accept selections. Bad accumulator assembly? Possibly, but since the lights don't work, several of the tubes tested "bad", and the condition of the electronics is a huge "unknown", I decided to tear-out some of the "questionable" electronic components for rebuilding, including:

The amplifier...


The power supply...


And the accumulator assembly....


Once I removed all of the electronics from inside the unit I found about $4 worth of change that was lying (hidden) underneath them! I found a Buffalo nickel from 1937, a dime from 1928, and many coins from the 40's and 50's. I'm not a coin collector, nor do I know of any, but I'll put them in a small envelope and place it back inside the jukebox (for the next owner to "discover") once it's completely rebuilt.


I ordered an amplifier rebuild kit from Vern Tisdale a few days later, but I still need to source the parts for the accumulator.

I also removed the horn tweeter, hoping to find a rebuild source (no luck on this yet), and from the rear the unit now looks rather empty...


At the same time I removed the front door assembly and glass (for safe keeping) as well as the front selector key panel (for restoration). I don't have a picture of it, but I cut a piece of plywood to cover the entire front of the unit, protecting the woofer (which will be rebuilt as well).


The next goal is to rebuild the power supply and accumulator, re-install them, power it all back up again, and see if I can't get it to accept selections. Once that is accomplished, and I know everything works as it should, I'll tear it down completely for re-chroming, re-plating, and cabinet work.
