Tuned a 1921 SSM not long ago - it was very unstable especially in the treble. Owner said it had been rebuilt. There was certainly a new pin block in it - I could fit two credit cards between plate flange and block in the bass - the treble part was ok. Wonder if this sort of instability could contribute to broken plate? Gene -------------- next part -------------- An HTML attachment was scrubbed...
