Hello, Stewart,

How long did you bake? At what temperature? What kind of oven?

There are some cassettes that do not respond to baking. In fact, I think 
a smaller percentage of cassettes do respond to baking than reels.

This is why I use D5 (decamethylcyclopentasiloxane) for this. It 
ultimately evaporates.

I place a cotton swab in an existing supply-side hole and inject that 
swab with D5 using a syringe.

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:

(the above two lines need to be combined into the URL).

Cheers,

Richard

I have tried playing them on several decks and there where no changes.  I tried reshelling them thinking there might be some drag in the shell causing it. No change.  I also tried baking them but I did not expect that it would help. It did not.

Quality tape transfers -- even from hard-to-play tapes.
