I am hoping that you or someone may be able to offer some advice. I have a 1990 Rowe CD-100A which I purchased a few years back in Michigan; I live in the Cleveland, OH area. When I first purchased the machine, it seemed to work fine. After a few months of owning the machine I hosted a party. About an hour through the party, while the machine was playing a song, the sound started cutting-out momentarily, then the music came back for a few seconds, then cut out again and again with duration of each "cut-out" becoming longer and longer until eventually barely any sound was coming out of the machine. During the party I ejected all of the songs in the list to play, turn the machine off for a minute, then turned it back on. The machine played a song and a half then the music started cutting out again. Frustrated, I turned the machine off. A few months later I called a local "jukebox repair technician" out to look at the machine on two occasions. The problem with the machine was intermittent as each time the "jukebox repair technician" came out, the machine would play fine for several songs, however other times (when the technician was conveniently not present) the music would start cutting out almost immediately after I would turn it on. The second time the "jukebox repair technician" came out, he replaced the Mech Control with another unit he had. After a few songs of play, the issue came back. Over the last few years I haven't had alot of time to mess with the machine but am now getting the desire to start tinkering with it again. I contacted Bruce Wentworth of A&B Jukebox Repair in NH. Bruce suggested that I send him my Mech Control and CD Pro units to be tested as he felt those were most likely the issues. After several hours of testing, Bruce found both units to be in good condition. Again, the sound cuts out; it is not a CD-skip. Usually, the machine will play one or two songs before the sound begins to cut out. Usually the duration of the cut out starts with a duration of a split second gradually lasting several seconds to constant. Bruce suggested the problem might be the Pre-Amp but I wanted to get some additional advice.
