Seeburg SC1 Wallbox MP3 mod with speakers

[kellimcc]

I acquired 4 working SC1 wallbox units recently. I’ve already modified one to work with an iPod and external speakers and now I’m working on the second one. I would like the internal speakers to work on this one.
I got a TPA3123 class d amplifier and wired it to internal speakers but I’m not getting any sound out of them.

Do I need to modify the volume control?
Does any one know how or have instructions how to wire it and have internal speakers work?

One more question, anyone know how I could make one of these wall boxes work with my Rockola Rhaposdy ll jukebox?

The audio is routed through a relay (K881) which is energised when 25V AC is present. You could just link out these two contacts. Does your Rhapsody II have a stepper fitted?

Did you use a MP3 ?
