AMI 200 Jukebox

I recently purchased an RCA sign from a gentleman who also showed me this jukebox,hinting that it may be for sale.He assured me that it worked though could not demonstrate for me as it was absolutely unreachable at the time, stored at the back of a large storage room simply packed with antiques.He played me a Wurlitzer and a Seeburg 78 juke which were not for sale ,but surely needed some electronics updates, so I would expect a few issues with the 200. He offered to fish it out on appointment for a demo.Are there any bugs,gremlins or cycling anomolies common to this machine which I might look and listen for? Visually it was sharp(though I would tint the glass)He said he paid $750 for it. I'd like to here from AMI 200 owners and others who are familiar with these machine.Good day.
