Hi, I'm a new poster here. I finally bought a new MZ RH1 to replace the cassette WM D6C I was STILL using for gig and field recordings. On balance, the sound quality is unbeatable, however... When recording from the mic input (so far I've only used a studio mic - a sennheiser MD441 through a stereo adaptor then through a grado 1/4" to 3.5mm jack adaptor into the mic socket) I notice audible ticking that seems to be in sync with the display. Turning the display off has no effect. Also there is some of what sounds like motor noise. At current levels, it's sort of ruining any recordings. Line in recordings are fine. There is also sometimes static noise if I touch the controls. Turning the machine around sometimes solves the problem. It's almost like it isn't grounded properly. Just wondering if this is normal before I go marching into the Sony service centre. thanks, Tony
