| Hi Jim,
| It's not the resonator. If that massive rim is counting on 
| the resonator to do anything, it would affect the whole 
| piano, not individual notes. I've found when individual notes 
| go out badly in a short time, at least with a usable 
| pinblock, It's just about got to be a rendering problem of 
| some sort. I'd start there.

Like -- what is the deflection angle coming off of the agraffes? And how much
felt does the string travel over between those agraffes and the tuning pins? 

Are unisons going out across the scale? Or is it confined to one or two
sections?

I agree with Ron, it's not the so-called "resonator." Bearing in mind, of
course, that resonating is exactly what you don't want that thing to do.
