<DIV>I had forgotten about the captive screws. Yes I did like those.
The latch that held the guide closed was also on the other side. The
brushes were interesting. I remember having to have spares on the old low
band heads that I had for the TRT. </DIV>
<DIV> </DIV>
<DIV>There was also a special tool for somebody's head to adjust the
transformer. An Allen driver with the plastic handle ground down. I
never did an adjustment to the transformer as I could not see why to
do that. If the head worked, why fiddle with it?</DIV>

<DIV><FONT size=3>I don't have enough experience with the RCA heads to do a
detailed comparrison, but one simple thing that I liked about the RCA head was
that all 3 of the mounting screws were captive and exposed. Made for
easier removal and installation.</FONT></DIV>

<DIV><FONT size=3>As for design, didn't RCA have air-bearings
first? Ampex had rotary transformers first.</FONT></DIV>
