[QuadList] 1970 3M Industrial Tape Sales Sheet coming soon

[Pat Shevlin]

I have just completed restoring our IVC 960.  Picture looks significantly
better than the 800 models.  It’s the only IVC 1” machine I have that will
play 1.5 hrs.

The IVC 900 (& 960 editing machine) were highband (7.06-10 MHz)
tension-servoed

machines that would accomodate large reels for 1.5 hour programs.  Used
with the 

DOC and "wide" window (40 µs?) 4102 analog TBC, the machine gave better
playback

performance than many contemporary quad recordings.  (Many, maybe most,
quads 

at the time did not have Velcomp or Autochroma to fix guide-position errors
caused 

during recording.)

 

I had the pleasure (!) of working with the first two On-Air 900s at KFTY in
Santa Rosa

in 1972-73, one on in the truck, and one in the studio.  Not much publicity
given to 

that 1st roll-out status, as it was more of a beta site than anything!  At
least IVC was

less than 2 hours away!

Ted:

I didn't see anyone else answer your question, so......  IVC 900 series is
the answer.

 

And this fits into the discussion about IVC vs Ampex.  The 900 series was
more advanced than the 800 & 700 series, and was more on a level with the
VPR-7900 series.  When comparing the "formats", you have to be careful to
compare both the format itself and the particular machine model being used.

Trivia question: Â Can anyone tell what machine a 12.5" reel of Scotch
361-1-7500-VRB was used on?

 

The tape was sold two reels per carton at $213 per reel in 1970. An empty
reel was $17.

 

Clue: Â The same machine would play reels of 361-1-1075-R139B andÂ
361-1-2150-R139B if they were recorded on other machines that used the same
format. 

 

These smaller reels were $34.55 and $45.30 per reel in cartons of five.
