K, first off, it plays 78's, not albums. The jukebox forums shred people for less. Then shred them again for not having bought the manual.
check with Denny at Victory glass, they carry hunfreds of manuals, not the photocopied unreadable stuff you can find on Ebay. . They also carry repro and original parts, and Denny is quite knowledgable.
Te coin gear I'd check with Lloyd at Coinopwarehouse, also for any other trim you or parts you may be missing (coinopwarehouse.com) Lloyd also has a page on Facebook.
Durfee Coin-op
http://www.jukeboxparts.com/Wurlitzer-parts is another go to spot for parts. He also carries needles for most boxes.
If you can, ask the seller if he knows if the machine has been serviced, ie the amp rebuilt. 70+ year old capacitors have a nasty habit of burning out,and blowing out.
Congrats and welcome to the jukebox club. It's cool to see the look on someone's face who has never seen a record play, let alone a jukebox that wasn't all Cd's or mp3. Even when it's not playing, it looks darn cool.
