I service and repair AMI, Beam Echo, Rockola, Wurlitzer and some other jukebox amplifiers. I do not repair the machines, but if you are having problems may be able to recommend someone in your area. If you are confident that you can safely remove the amp from the machine, just bring it or send it to me for a quote. Before you do check, that your problem is not being caused by the cartridge or speakers to save a wasted journey. Many amps that I see have been soldiering on, way past their best for some time and a good service can work wonders for your machines sound!
