Thanks to all for the suggestions. Yes, the DATs are being played on the
same machine that they were recorded on. Unfortunately, I don't have another
machine in house to test the tapes on, so it's unclear to what extent the
issue is a machine problem, a tape problem, or both. There should be a
reliable service person in the area to check on the head and perhaps do a
cleaning, but I will have to investigate that a bit. It sounds like that
might be the right next step since it's feeling more and more like an issue
with the deck.

Subject: Re: [ARSCLIST] DAT glitches
Two things I can think of. First, try another machine. The da-20 doesn't
last long and you might have run enough tapes on the machine to need to
replace the drum. Playing on another machine will tell you if the
problem is in the cassette or the deck. Eddie Cileti recommended the
Sony 500. Second, your transport might have accumulated dirt and so
needs a cleaning. A cleaning cassette wont do the trick because you
might have loose magnetic particles or other gunk that came from the
tapes. Is there a reliable service person in your area that can check
the head condition?
