Hi, Joe,

Is this Sony PR-150?

If so, it is a known tape that does NOT respond to baking, but I'm not 
certain if baking exacerbates the problem or not.

PR-150 was one of the tapes I tested for my Tape Degradation paper where 
I introduced the cold playback technique. It also can be transferred 
with liberal amounts, of D5.

Both techniques are discussed in my paper on tape degradation that was 
originally presented at the Audio Engineering Society's 121st convention 
in October 2006 in San Francisco was published in the ARSC Journal in 
the Fall of 2008. It is available here:
http://www.richardhess.com/tape/history/HESS_Tape_Degradation_ARSC_Journal_39-2.pdf

Further, I have a resource for all to use (and request additions to if 
they have new info) that lists tapes with known or suspected problems 
and the known cure (if any).

Cheers,
