I have a JVC-CA-MX70 system with a remote, manual etc for parts. Its amplifier went bad, too, but it doesn't give any humming. Instead, it develops static cracks in both channels and the bass channels start to pop up only 10 or so minutes after the system is playing music. I tried to solve the static problem by spraying DeOxit into the volume potentiometer. This did not help; even tearing this pot apart and extensive spraying of its innards did not help too. So if anyone needs any part of this system just let me know. One can try to use component boards from my amplifier to get rid of humming problem in your amplifier. Alternatively, if you have an amplifier that gives you hum AND there is no static “cracks” or other defects- I can buy it from you. Please let me know.
