The 100G used the MRA4. You can find a decent copy of the schematic here

Replacement power supply chokes for similar Seeburg amps were discussed here a few years ago and the Hammond 158Q was deemed a good fit - if that helps?

What model did they come in? I think someone told me that they came in hideaway units. I did somehow find a parts list for an MRA4, and it's very close to an MRA5, I'd just like to have the proper schematic. I don't mind buying a manual, but I don't know which one. The particular one I'm working on evidently fried the power supply choke and to make up for it, they made C1 out of 3 caps to get close to 300uF.
