Well I finally got the jukebox playing correctly picking up the records and playing and returning with no hang ups.
Problem was just did not sound real good.
Since I had rebuilt the amplifier and rewound the output transformer and installed a new cartridge/needle. I decided to give a try at re-coning the 15"
speaker. The cone had some small holes and the outer part was very thin.

I had to order the parts from three different places due to the odd sizes of the voice coil and spider the is glued to a frame of it's own.

Here is the spider and frame that had to be cleaned up and new one glued on.

Above pic is the voice coil , spider, and shim in position for the cone. This took a lot of trial fitting to get the voice coil and spider set to the right height.

Finally complete. I tested it with my audio generator and just an hor ago had it in the jukebox and sounding soooo much better.
