[QuadList] Searching for SMPTE standard for Ampex Type A formatvideo recording

[bill.spencer at northstarstudios.tv]

Type 'A' was always anything that wasn't type 'B' or 'C'.   When the
SMPTE standard for type 'C' was adopted, Ampex and Sony made small
adjustments in their machines to conform.  I have converted several
VPR-1s into VPR-2s, but Sony always made you send the machine back and
let them do it.

 

Unfortunately, many have called a whole variety of early 1" recorders
type 'A' such as the IVC 800 series, Sony 300 series and Ampex 7000
series, but I like to only refer to the VPR-1 and Sony BVH-1000 (no A,
because the A made it a C) as type A machines.

 

This is why there is no reference to a SMPTE type 'A' 1" specification
as there never was one.  There may be some manufacturers details for the
VPR-1 and BVH-1000 that one could peruse to see the differences.

 

Just my 2 cents worth!
