Yamaha GH-1

Yamaha used to provide a kit to improve the low tenor with wound bichords.  

I did this once, and had  a favorable result.  Since I was replacing 4 plain 
trichords (6 hitchpins) with 4 bichords, I had to add two hitchpins.  I 
didn't get them in the exact right place, so my nice new Yamaha strings 
didn't match perfectly, but it was a big improvement over the original plain 
wire, and the piano owner who had been through a bunch of other technicians 
was happy.

You also wind up with four dummy tuning pins (assuming you're doing this in 
the field and not plugging the plate holes.)

I don't think Yamaha provides the kit anymore, but they must have the 
information.  The kit had the strings, hitchpins, a drill bit for the 
hitchpins (I think), agraffes and bichord damper felt.
