Also found that R34 and R35 should be 10k resistors as well as R56 and R58.

Made the changes. I don't have svn access so if someone can submit the
attached diff for me...

Thanks.  So it looks like the code needs to be changed from 19k resistors to
10k.  That should make it sound right.

I'm not near a computer with svn access at the moment.  So if anyone want to
make the change, feel free.
