     Schaff gets away with an awful lot.  I'd return it!  If 
it's sposeta be 440, it should be dead on!

Subject: [pianotech] A432 Tuning Fork


Hello Everyone;
I just bought a John Walker tuning fork from Schaff in 
preparation for my tuning exam. All electronic instruments 
indicate this fork is 6-8 cents flat at room temperature.  I'd 
like to get some feedback as to options. My other forks average 
average to within 2 cents of C5 and A4 but the A4 one is 
aluminum. I was thinking of keeping and filing the John Walker 
fork, but wouldn't 6-8 cents require an awful lot of filing and 
mutilation of the fork? Another option would be to return the 
current one and ask Schaff to send one closer to A440. A final 
option I've considered is to purchase a Sanderson Accu-fork 
($165 Pianotek). Any comments would be appreciated.
Thanks,
Jim
