I've got a 45 vinyl Wurlitzer 1015 OMT I picked up a while back, and someone did a number on the wiring inside. It looks like while hooking up external speakers, they made a mess of things.

Right now it plays fine, but the volume is extremely low. It has the I84 amp and what I seem to be missing is the 70v input on the two transformers that output to the speakers; those black and white wires are cut on the terminal block.

To compound matters, the only manual I could find online is for the newer amp so it doesn't match up, and the schematics I have for the I84 amp don't show those terminal block connections.

I'm so close to finally getting to hear this one play, and a couple of wires are ruining the fun :-(

Can someone with a OMT take a look and let me know where those wires go? I'd be forever grateful. The connection I need help with is those two upper right transformers above the yellow box, where do the leads labeled 70v go to? The inside of my juke looks like this one:

I talked to John on Friday, he sent me the schematic for the I84 amp so I could wire up the remote.

Looking things over yesterday for a few minutes, I'm starting to wonder if this amp isn't on mute? The mute light is on (green) and I don't know if that's a normal condition, or if it's a dual color and red indicates mute, green is mute off?

This juke came with an infared remote, but is missing the receiver and remote interface to the amp. I wonder if it's saving the setting somehow as the instructions mention it would?
 
PROBLEM SOLVED! After a marathon day of soldering on the Exidy project, I took a break to tinker with this 1015 problem.

Thinking back to the broken wires and damaged cartridge, I decided to re-check the input harness starting there. The first thing I found was a missing ground connnection at RG on the back of the cartridge.

That got both channels working, but the sound was still way too low. Then, when moving the input harness around the sound spiked louder for a second. Moving the harness a little more got it to stay louder.

I then pulled the harness and luckily it had enough slack so I could cut off the last few inches where it had been cut internally by the mechanism; probably from being moved without being secured.

Now I've got full stereo sound, w00t! I don't know about you guys, but when something isn't working right, it digs at me until I fix it; and the payoff when it starts working again is that much sweeter.
