Rockola1428 wall box set up

I have a restored Rockola 1428 and matching wall box ready for wiring. It evidently worked for the guy who restored it but he is no longer available to assist. Per Victory Glass, there are no instructions available by manual for either the juke box or the wall box. I understand wiring the 20 selections in the juke box to the corresponding number in the wall box but there are several additional wiring requirements that I am not sure about. The juke box has a terminal labeled common so I'm not sure where that connects to the wall box? 6 volt to the 6 volt and 24 volt to 24? The schematic in the wall box says "24 Volt Ret. no Conn" ???
Very hard to read the yellowed schematic in the 60 year old wall box.
Thanks to anyone who can help shed some light on what is probably a very easy fix.

Hi Bryan - I think I have a schematic on this for the 1530 wall box. Let me cheecck my library and will advise.

I went thru my library and found the schematic for the 1428. Also, I opened up my 1530 and snapped a great pic of the wiring diagram that waas glued inside. Am still reviewing these but it appears pretty straight forward with 24v, 24v (return), 6V. The only quesstion left in my mind is the labeled "X" connection on the jukebox. I would try conneccting those three up and cheecck operation.

If you want pics of the schematics email me or I can see if I can post them somewhere online.
