we had  the  recorders  form Luke  AFB at the  transmitter site and we were 
responsible  for   cleaning heads  and changing  tapes!

The RD-142 was for recording air traffic control facilities
such  as control tower etc.  They did not work very well
because of the way  the four heads which traveled across
the tape couldn't be properly  adjusted.  Head switching,
and maintaining constant record/play back  amplitude was
almost impossible.  But by 1963 every ATC facility I  knew
of had one or two.  (Number 2 HD wooden pencil lead was
the  best brush for the rotating heads.)
The RD-142, which used plastic tape,  replaced the RD-115
which was a total loss.  Never saw one that  worked, and
they used 2 inch paper tape.
In 1963 I was at Kadena, and a  civilian contractor came and
installed a few rack-mounted recorders for ATC  use.  They
were 16-channel on to a 3/4 inch (?) tape.
Trivia, but  not a lot of people know what happens to the ATC
facilities when there is  an aircraft accident, or an "incident" of
some kind.
First, the tower  and ATC operators are immediately removed
from their posts, and escorted to  the base medical facility where
they are given a bunch of exams.   (This meant that these people
had to be replaced by anyone properly  qualified for the jobs, and
this meant sifting through the barracks and the  clubs, and rousting
qualified staff out of their easy  chairs.)
Then,  the voice recorder tapes were removed from the  machines,
and stored in a safe for further inquiry.
Our Group Commander,  a Colonel, was never happy when these
things happened, even though it  wasn't our fault.  The tape recorders
saved our butt on many an  occasion.
End Of  Trivia.
