[pianotech] wurlitzer grand action brackets

[Will Truitt]

Hi Everyone:

I have a customer with a Young Chang grand from those golden years of
growing action brackets, and the action just plain doesn't work at all.
I've done a few of these, and I tried to contact YC through their 888
number, but kept getting a busy signal for several days.  So I did some leg
work and found another number to call.  Since others have had difficulty
getting hold of YC, I think it appropriate to share my success in getting in
touch with them.

The Tech person is Derrick Cornejo.  When I called 310-637-2000 ext 117, he
answered on the second ring.  We got our business done and I should have the
brackets within a week of ordering.  

For anyone who might need it, the address is:

Young Chang North America
19060 South Dominguez Hills Drive
Rancho Dominguez, California 90220

It could be other things, especially if it does not show the exact symptoms,
decreased letoff being the most obvious.

If it's just general regulation, it could be Unstable keyframe, unstable
environment, warping keys and hammer shanks, etc. Lots of possibilities.

After this many years, bad action brackets should show the problem as well.
The smooth sides of the defective brackets should look a little lumpy after
20 years.

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?
