homebrew High Band playback mod done at then-Kaiser WKBD Detroit, was designed
by my good friend, the very brilliant Michael Hennessey.
<div>Before Mike joined the WKBD staff, he had worked with me at Wayne State
University TV. He and WKBD provided us with a copy of the instructions for
this procedure, which I installed on our TR-4.</div>
<div>This allowed for playback, but not record, of tapes made on our TR-70 and
from outside sources.</div>
<div>I still have a copy of Mike's detailed instructions, drawings and photos
for this project.</div>
<div><br></div>
<div>Regarding the TR-5, it was our Remote machine and backup studio recorder
at WSU in the monochrome days.</div>
<div>Yes, it took at least two men and an ox to push it up the ramp into the
truck, and haul-in remotes were always a great treat.</div>
<div>Ours had wheels with at least two locking. HW panels were ball bearing,
no air kit.</div>

<div>Hi-banding was an expensive operation for a small station in the 70's.
We had moderate success hi-banding (playback only!) a couple well-used
TR-22's by following a homebrew procedure given to us by some helpful folks
at a Kaiser Broadcasting station in Detroit, where the non-RCA conversion
was probably designed. Widening out the bandwidth of the RF stages was a big
part of the process.</div></span></span><br class="Apple-interchange-newline"></blockquote></div><br></div>=<br><br>Please
