Any Ampex users out there?

I recently purchased some Ampex gear.....actually quite a few pieces. A AG440C with the servo motors and "B" electronics which should be delivered next month. I also picked up a 354 with a transport and several 350's with a transport. These tube types require updating so these probably will be a year out before I get them in my system. Would like to hear about your Ampex reel 2 reels.
