<DIV>What do you want to know about the TR-5?</DIV>
<DIV> </DIV>
<DIV>Spent many a night in a TV truck shading cameras and running tape as
we recorded local sports games for later replay. The state HS athletic
association forbid Friday night game replay till after 10 PM. Very small
station/crew. Our TR-5 was low-band (of course), but it did have an editor. We
were told that if you stuck in an RCA high-band head, pictures would look
better, and they did. Suppose it was due to wider RF bandwidth.</DIV>
<DIV> </DIV>
<DIV>Portable? We rolled it into the truck on Friday afternoons (or before any
non-live TV remote), then back into the control room once the truck returned.
It was needed during the day at the studio for production, if the high-band
machines were needed for playback. Two young guys could push it around easily.
Rugged little beast, hardly ever broke down despite all the rough handling and
bumping around in a truck. Just make sure the hundreds of gold pins on
the wiring harness were firmly seated in the Amphenol connectors. Otherwise,
you could get a bad case of "blue-ribbonitus".</DIV>
<DIV> </DIV>
<DIV>One fact I still remember: the headwheel panel contained a
three-phase motor, but there were only two headwheel amplifiers. A weird
transformer-capacitor combination synthesized the third
phase.</DIV></FONT></BLOCKQUOTE></DIV>
