Ampex ACR-25 Commercial Player Question

[TVBeeGee]

Many of the parts in the Ampex ACR-25 were also used in the Ampex AVR-1 reel to reel machine, including the Mark XX video head, the signal system and the TBC (buffer) boards, plus many other parts. Many network and broadcast facilities had both models. The AVR-1 featured 30 ms lockup time with any reel size, exquisite tape handling, and could also play tapes smoothly with damaged or even totally missing control track. Shuttle acceleration in the AVR-1 reel to reel machine was limited to 300 inches per second per second...unless you were Compact Video...who modified their machines to shuttle and cue at the same 600 ips speed as the ACR-25. This made for astonishingly fast checkerboard auto-assembly online editing for numerous network tape shows in the 70's.
