[peel] Re: tape screech

[aadam jacobs]

Azimuth (and forgive my previous misspellings) doesn't, or shouldn't have anything to do with tape squealing.
As far as I'm concerned, if WD40 works for that one final pass to digitize, why not? The alternative is not hearing it at all, so....

This will probably make the Azimuth-Evangelists cry but I
got rid of some fairly heavy tape screech on some of the old 400 box tapes by
spraying WD40 into the case and then doing a couple of FFW and RWD’s to work it
through. 
 
Not sure if this is too good for the tapes in the long run
but I figured we were only interested in playing them the once in order to rip
the content

I've got a commercial tape from 1981 (Kampuchea concerts) with some screech that I haven't been able to get rid of. Same thing with an old commercial tape of the Damned's Black album ; never had it on a DIY/blank cassette though ! Tried everything - loosening the tape, re-housing, dif players.The problem must be in the tape material itself. Aadam is right though, sometimes noise is caused by restricted tape movement.

You have a day or two to get the sound off the tape before it blows up! (well not quite, but the tape soon reverts to screeching and will be in a worse condition...)
