[QuadList] High and Low band on AVR-2 via new board set (was Multi Standa...

Please excuse my ignorance because I really don't know, but I have seen archived ads in European used equipment resellers for a couple of Ampex AVR2-U's that said they were universal machines capable of running both NTSC and PAL.  

Could somebody have been marketing a modified machine for Europe?

NPC on a TR70 is not its best servo mode, it can be difficult
It will run all standards or at least the TR70 will
Tr70 B is the best, try and avoid the TR 70C the digital servos can be unforgiving

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.

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 for further info.

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.
