[Jukebox-list] AMI R-84 Jukebox speaker problem

[Ina-Gadda-Da-Records]

Howdy,
I have a problem with output on the left side speaker of my AMI jukebox Model R-84 built in 1980. The Speaker works, but no matter how much power adjustment I put to it, there is a much softer sound than that from the right side speaker. There is no buzzing, so the speaker is not blown. Might be an amplifier output problem, but not sure how to check it and the manual doesn't really identify this problem. Can anybody help?
Thanks,
Dave
