[Jukebox-list] MRA4-L6 Schematic

I've looked and looked for a schematic for an MRA4.  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. Tony
