Thanks for suggestions. Theo the buzzing is from the remote not the preamp and loud enough to disturb listening; the remote still functions although no buttons light anymore; batteries have been replaced; the remote case does not open easily and looks like it would have to broken open, which I may try since it would be a useless remote anyway. It started as a high pitch whine now is an annoying constant buzzing. Anthem says unusual and that Pronto has Anthem codes but I like the hands on style versus menus. They also say to check the Harmony line as they may have Anthem codes or I may look at a learning remote. Thanks again.
Anthem AVM20 remote control buzzing
I've got an older AVM20 preamp (still sounds great) and the remote control just started making a constant annoying buzzing sound that won't shut off and is loud enough to hear during music. Is there a way to fix this or am I left searching for a replacement? Anthem says the factory one is $129 but would like to spend a lot less; only need basic functions. I like direct access buttons like the one that came with the preamp versus screen/menu types like Pronto. Thanks...
