AAdam..

  Based on your question, you may have better results transplanting the
electronics and leaving the head/deck geometry alone on the non-clogging
deck.  Hope this helps.

Best,

Gary

Hi!  I'm new to both DAT and to this list, and would really appreciate
advice about a problem I'm having.  I have a Tascam DA-30 deck and a
whole set of archive DAT tapes I need to play.

The problem I'm having is that the tapes were recorded on a Sony
TCD-D8, some at regular sample rate (48KHz) and some at what seems to
be an extended play or long play mode at a different sample rate (it
comes up 32KHz on the DA-30s monitor).

The problem I'm having is that while all of these tapes played fine in
the TCD-D8 (several years ago), only the 48KHz seem to currently play
on the Tascam.  The machine registers the start ID and control track
numbers, but it shows no audio present at all.

Do I   a)  need a different player (must it be Sony)?
         b)  need different settings of some kind?
         c)   need to give up on these tapes (they are 10 years old,
have they deteriorated?  But why only the extended play ones?)


Many, many thanks for your perspective.  The contents of the tapes is
extremely important to me--the last recordings of the voices of
several relatives who have passed away.


all best,

Greg

There are 2 32kHz formats used: 16-bit linear, and 12-bit non-linear
(the latter is used by Sony).  I believe there are some non-Sony decks
that handle 12-bit nonlinear; the most likely are Denon, and some
Pioneer.
