<div class=MsoNormal><SPAN style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: 'Helvetica','sans-serif'">My post about changing the speed of the capstan was referring to your description of what was done to the pulleys on VR-2000 or 1200 machines. Unless I'm missing something, that would change the tape speed, which in turn changes the video track specifications.</SPAN></div>

<div class=MsoNormal><STRONG><SPAN style="FONT-SIZE: 10pt; COLOR: green; FONT-FAMILY: 'Arial','sans-serif'">Agreed, but ONLY for playback where the capstan speed is controlled by the servo. If the machine is for playback only, no problem, although I would have guessed that an electronic modification would have been much easier. My concern would be in record, where the capstan is fed a fixed frequency, and therefore the speed is affected by the mechanics. The servo has no way of knowing what the actual velocity of the tape is in record. If it has been changed by a mechanical modification, then the track alignment will be non-standard.</SPAN></STRONG><SPAN style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: 'Helvetica','sans-serif'"></SPAN></div>
