rock-ola

I was given these today. Can’t find a thing on them. Rock-Ola 50485-A. Anyone have any information at all? I’m going to take the old grill material off and check them out. But online has been nada on results for a jukebox manufacturer who made stand alone floor speakers.

So, there’s a Rock-Ola 431 Jukebox available near me for a good price and I’m wondering if I can remove the 50 Watt Stereo Tube Amp & use it outside of the jukebox? I’m guessing I would have to remove the power supply and the Amp but would I be able to plug a preamp into it? There doesn’t appear...
