1964 Rock-Ola Princess sound stopped working.

[fallsnative]

I have a 1964 Rock-Ola Princess in great working condition, however today I turned it on and it plays however I now have no sound. It has internal speakers and jacks for external speakers and none are working. I am assuming then it is something to do with the amplifier, but that's a guess. I don't have a manual for the jukebox. Any ideas on where I can start troubleshooting? Any help is appreciated.
