I forgot about your new boards.  The problem is still the servos and  the 
TBC.  These are different between the 525 and 625 machines.  The  TBC in PAL 
is not compatible with NTSC.  So again it is a major  issue.
 
He wants to do both NTSC and PAL.  If it were not that, yes an AVR-2  is 
the answer.  But with both formats, the Universal Colortec is the only  thing 
that allows the PAL VR-1200 to play back NTSC tapes.  
 
How can he get around this with the AVR-2?  
 
That is one of the nice things about the VR-1200.  It has built in the  
servo system for both 525 and 625.  The FM standards are all there.   Both 525 
and 625.
 
The Heterodyne issue is not an issue.  In fact a standard Colortec  would 
handle this in the Non Phased Color mode.  Same for the early RCA  CATC.

I would go for it if all one is doing is  a single standard and High Band 
only.  If not, then you are stuck with  a VR-1200 series.  




No quite so... as a result of the first new development for Quad  videotape 
in decades!


As we announced at the Quad/Editor/Telecine lunch at  NAB... 
There's a new board set that will take care of making an AVR-2 capable of  
running high band c/m and Low Band color and monochrome with just a few 
switch  flips or turns.


This makes it possible to standardize on the AVR-2 as a machine of choice  
for these tape formats. 


The board is an outgrowth of Ken Zin's execution for his own AVR-2. He  and 
long-time colleague Al Sturm have collaborated on the design. Al is  
handling the manufacturing details and I'm marketing it.


The set replaces the demod card, and modifies the EQ/Switcher card to  work 
with the new demod.  It can be set up to work with NTSC and  PAL.


Please contact me off-list at _ted at flashscan8.us_

Beyond Low Band Color...
There's also the possibility of a slightly different board set to allow  
AVR-2 transfer of RCA Labs color and RCA color, those wonderful pre-low band  
heterodyne formats used on the WRC-TV dedication (Eisenhower tape), the  
"Evening with Fred Astaire" recordings and other shows done at NBC or on early  
color RCA machines.


That's taken mods to 10 or so AVR-1 boards to accomplish. QuadList member  
Ed Reitan did it in 1987/88 to enable recovery of the Eisenhower and Astaire 
 tapes (among others) with Don Kent operating the KTLA machine. That's now 
in  CBS-TVC (with the boards, I'd think.)


QuadList member David Crosthwait did it for one of his AVR-1's a couple  of 
years ago and presented a short talk w/powerpoint at the AMIA 'Reel Thing'  
in St. Louis.  It took some late night soldering-iron sessions and a lot  
of reference to the RCA TRT-1C manuals he has to reverse engineer the process 
 and develop his set of mods.
