I have several Crowns and Ampex's.......
Ampex 350's.....I have six of these....my goal is to build a 1/2" 4 track and I have all the parts to do it including the original headstack and sel-sync....
This is a 440C with DC servo motors and B series electronics
This is a Crown CX844 with Vari-speed,Lo-Z's,and sel-sync...this deck left the factory in 1969...loaded up with every option....price tag at the time was 5K which was a shit load of money back then....still is. I also have another CX844 and CX824 both have been recapped. I also have a Ampex 354 which is being rebuilt....remember it's only money....
