Update: It took a few emails but Marantz Pro finally got the ball rolling and gave me a return authorization for service or replacement with Superscope Technologies in Geneva, IL. That puts me out of commission for the interim as I don't have any back-up equipment yet. I got some advice on another thread to consider the Tascam DR-70D as a cheap back-up but as inexpensive as it is, it aint flying with my girlfriend at the moment. Short of going to the WSP/UM/Tauk show at Jones Beach in a few weeks and actually... well, not taping it, might anyone have any last minute suggestions?
