<DIV>The links below don't work for me. They just go to a logo page for
oldradio.com. I looked at the site but could not find what you have
described.</DIV>
<DIV> </DIV>
<DIV>I have some RCA technical papers and pictures of the helical head assembly
that was used. Don't think it ever became a real product for television,
but may have been used some for wideband recording.</DIV>
