ROWE AMI CD 100 speaker Hum

[sipancio]

Hello- I have a Rowe AMI CD 100 which had been working great. Last year all of a sudden a hum was coming out of the speakers (didn’t matter if it was turned on or not). It still plays and sounds “ok” but there is a constant hum in the background. When I disconnect the amp the hum goes away.


I tried replacing the amp- however my original amp was part number ending in 903- I could only find similar amp ending in 902 (must be previous model). It worked but sounded even worse with this amp. In addition regardless of either amp I try- the 8A fuses keep blowing on the back of the amp as soon as I switch the jukebox on.


Any thoughts on a resolution to this problem?

Does anyone have any advice on this issue?- I keep trying to trouble shoot but having no luck.

I'm still pretty new to the Jukebox world, but I've done plenty of reading. A lot of times hum comes from bad filter capacitors. The electrolytic capacitors in the amps degrade over time and when they get far enough out of tolerance, you will get hum. You really can't trust anything you buy off eBay as working, even though they will say "tested good". If you are good with electronics, you can try replacing your capacitors yourself, but only if you have done that stuff before. If you haven't reach out to Jeremy Wallace at jeremysjukeboxrepair.com
