Matt,
 More info please. Was it a P22 (or a relative) from the Thomaston plant? 
Look for the T before the serial # .
 It was a problem that I think was eventually corrected , but the older 
models had a sharp departure angle from the v bar to the pin ,especially in 
the lower row of the bichords.Combine that with a plate that was quite rough 
and string breakage was common. I'm not sure about the monochords as you 
describe but as Paul mentioned sometimes its just your lucky day.
I had a contact way back when with  Yamaha tech services and replaced  scads 
of strings on this model .
 A little protek might  help but be  sure to keep the stuff away from the 
windings .
