it could be just an alignment problem...i had the same problem with my d8. pro-digital charges $75/hr for repair. if its just alighment, like mine was, you may be charged $75...if it is complete head replacement 200-300 sounds right.
a funny pro-digital story. i went there monday to get a 7pin i/o cable and to pick up my rmr-d3 remote commander which had a bad internal fuse. paul is sitting there at the desk in the front, and rattles off a bunch of this is unit is compatible with this, but not that...he really seems to know what he is talking about.
we start talking about business and he tells me portable dat repairs are steady, but home/studio deck repair is lagging. we then talk about dat's competition, jb3, sound devices 7 series, laptop stuff.
paul gets up to show me a marantz solid state recorder, and when he stands up to show the marantz to me he is not wearing shoes...
just white gym socks sticking out of his blue jean leg bottoms. i almost cracked up.
as i re-read this it doesnt seem all that funny, but i still wanted to share it with you. i guess if you have ever been to pro-digital you may know why i find it funny.
