Its the BA662 that fails a lot.  I'd stay away from the Synthrestore bits,
apparently their full replacement doesnt sound very good ( ie : retune all
your originals to match the replacement... )

Yes, I've got one of these in my 106.  Sounds perfect.  I wish the price was
less but at 60Euro its not bad.  All standard parts as I've mentioned before
( LM13700's I think, now I cant remember.  Either 13600s or 13700s... ).
