did you find a HGS Amp? There are alot of guys lookin for them. The HGS amp is CRAP I was talking to a Velodyne Rep and He as had his HGS amp quit alos. that is why you see so many on ebay that are dead. Velodyne can replace the amp but it is best to dump the Idea and ebay it off and up grade to the DD series as i did and you will be happy
