<div><WBR>Thank You!! Great memory. The other one was perhaps a 516. Did you try the suppression pulse route and did it help at all with any other TBC's? I tried it with Sony TBC2000 and 1000. Try monochrome? I really had no luck to mention withe either one.</div>

<div>CVS had a DTBC it had either a 16 or 20 in it's model number which had an optional extra wired in small board mod for segmented machines. There may still be some around, but look for the board. AF put one in a 1200 D or E(?) and made it smaller than an AVR 2, you could roll it around anywhere.</div>
<div> </div>
<div>I have also played wilth DTBC's and the 2000 also with no real luck. Widening out the supression pulse and moving it around showed some noticable results, but no cigar. Might not have too bad in mono, but never tried it.<br>

The design is very different. I have tried many different models, not
expecting them to work, but just out of curiosity. NONE of them, from
older, early generation TBC's to very modern designs will work. There are
two main problems.....first is the different nature of the timing error
between segmented and helical, and second is that many of the early designs
as well as later and less expensive models were not designed for use with
direct color recovery. They rely on the heterodyne processing in the VTR to
recover the color signal, and that's the market that most of the TBC's were
designed for.
Merlin used several different models of NEC TBC's but I believe most of them
required some degree of modification. They also used an Adda VW-2 and an
Ampex TBC-800, both with some mods . You can find info on these on our
website on the Merlin Literature page.
