Rowe Cd100E Mute Circuit

This jukebox does not mute the amp when in stand by mode and the AVC, when switched to the on position, lops off a third of the volume when it's activated at the beginning of a song, annoying to say the least. I do not have the manual but have repaired this type of amp in the past such as rebuilding the driver boards, power amp section etc. Has anyone had this problem and how did you resolve it?
Cheers, Steve

Jukeboxes were designed to provide entertainment in public places - bars, restaurants, etc.
The noise level of such places was higher, obviously, then a home setting.
That stated, the AVC circuitry was *designed* for the noisier places, and wasn't annoying, so there's nothing wrong with it, really.
Just turn it off, as an option.

Steve,
Fix the mute problem, and your AVC problem will "go away".
Mute problem is either the plug on the inside of the pre-amp board is "off", the plug on the outside of the amp is"off", or the triac circuit in the MCC has failed ( could also be the MCC plug failing). Can be the mute relay too--although I have never seen one fail---Ron Rich
