[pianotech] wurlitzer grand action brackets

[Gary]

I have a client with a Wurlitzer grand that is exhibiting every 
indication of having the growing action brackets.  First suspicion was 
when she told me that it had been regulated twice in 7 yrs
. I got the model and serial number, which indicated it was built in 
1989.  I've spoken with Young Chang, and according to the fellow I spoke 
with, it didn't fall into those yrs in which the bad parts were used.
I've seen enough YoungChang/Weber/Wurlitzer pianos through the years to 
know the problem when I see it. 
The customer is willing to pay for another set of brackets, as she 
bought it second-hand and wouldn't be covered by warranty anyway. 
What else could it be, but the brackets?
