<font color='black' size='2' face='arial'>Hello Guy,
<div><br>
</div>
<div>Burbank had two 70C's in edit 3 (known as VTR 22 and 24). Same type RCA (EECO) programmer and GVG switcher as edit 2. Those edits were good too as with the B's. The problem we ran into was erratic playback servos breaking up for some (usually) unknown reason. They were fast lockup and were clean in terms of the signal system, but otherwise known to give us problems, especially in long-form closed caption sessions. If we were assigned edit 3, we were sure to have OT .</div>

</div>
<div>You are right: No capstan and drum servo drift adjustments on the RCA's other than whatever routine maintenance adjustments that were periodically made, as opposed to operator/editor attention to the VR 2000 servos (always being checked).<br>

David, <br>
My experience agrees with yours. Having done many edits back in the day
on a 2000, TR-22s and 70s, I also found the RCAs to be considerably
more consistent as far as edit stability is concerned. A note here:
all of the quad edits in my career were either done "punch and pray" or
with an Editec. I have never personally experienced a quad under editor
control. <br>
The RCA servos also seemed to be much more stable...regardless of
ambient temperatures, and didn't need constant fiddling with
discriminators and such on your knees in front of the Intersync. <br>
A more stable servo would certainly help to explain the observed
somewhat more reliable edit performance. <br>
I have not yet attempted any edits on these 70Cs, but it would be
interesting to see if the edits are as consistently good as the earlier
versions. The C has much "tighter" servos. <br>
Anyone on the list have 70C editing experience they would care to relate? <br>
