Rega/Mac C2200
Sorry for posting this in this thread, but AA doesn't allow me to start a new thread.
Does anyone know why when I hook up my Rega 3 TT w/Rega MM cartridge to the phono section of my C2200 preamp there is a huge hum that is loud enough to register on my amplifier's meters? This happens even without the volume set past zero. I tried new tubes without any change. The Rega doesn't have a separate ground wire, so there's no way I can ground it to the ground screw on the preamp. I plugged the TT into a different phono stage on a friend's Audio Research preamp and it's quiet. Does this problem sound like the C2200 has to be sent to McIntosh for repair?
