Ooh! Ooh! (as in Toody in Car 54) Here's something I haven't mentioned
before. Any of you ever try to play a mono upper-quarter track tape on
a full-track Ampex 600??? When I was at the Temple Univ station I
sometimes recorded something on my quarter-track home machine for
playing at the station, knowing that I had to use clean tape and record
on only one track. Our station was still in mono. The tapes played on
our half-track mono machines of various makes, on our half-track stereo
Ampex 354-2, on the damn full-track Maggie PT-6's, but it was BLANK
when played on our full track Ampex 600, and possibly our 601. I
finally discovered why. The head face on the playback head was convex
curved to play the center of the tape and miss the edges. It was a true
portable machine and they figured that it would sometimes play damaged
tapes and this would avoid playing ragged or creased edges. It took a
bit of experimentation, but I found a place on the Head-Track Selector
that would lower the head just enough to record a tape that could be
played back on a half-track mono machine and that 600.
