Wurlitzer 3300 Jukebox erratic audio issue

[rudy18d]

Quick question. I am trying to remotely troubleshoot a 3300 that was working fine in Texas but after it was shipped to Ohio it developed an audio issue. Seems that the volume on a record starts OK then fades out then back in erratically. They state that opening the top and closing it results in same issue.

I am thinking maybe an audio tube bounced loose during transport in the trailer?? Or maybe a wire to a speaker? Any other ideas to test you all can think of would be greatly appreciated.

Well, originally Wurlitzer 3300 uses the transistor solid state amplifier number 549. No tubes ...

I'd say all plugs and connections from cartridge to speakers should be checked first. Maybe one got loose while transporting. Especially when the jukebox was transported on a trailer, bad road conditions can shake the jukebox and cause vibrations, hence connections can become loose.
The tonearm should be inspected too. In case it wasn't secured well it might be out of adjustment.
