Peter,
No...this was done in the customer's living room, so I limited my self to living room appropriate modifications. I would have reconfigured the counterbearing and underfelt, but did not, as what I would want to do would be too difficult to do in a living room. So, no, downbearing probably stayed the same...I did not measure it pre or post, but made no modifications that would alter it much. I did use Paullelo O up through the entire tenor agraffe section, and dropped the tension a little, but I don't think enough to change any DB parameters.
DB sometimes alters tonal profile, but, in my experiments, not a real heck of a lot. And, anyway, tonal issues were not evident, other than could be addressed well and efficiently with proper hammer filing, and majorly important, by being able to nail a stable unison. Creating the conditions which allow you to nail and then shape a stable resonant unison is the biggest bang for the buck possible in any tone regulating, and it gets my serious attention before any other parameters are messed with.

Jim,
Out of curiosity, when you rescaled and restrung this piano, do you recall what kind of downbearing measurements you encountered on teardown, and then did you make alterations in any way to the downbearing when you re-assembled?

I had this instability with a GP-1 ...really their lowest of the low...until I re-strung, rescaled the entire bass and tenor. It wasn't just the low tenor, but it was all the agraffe notes up to the capo break...capo not as bad. I really think that the wire quality had a lot to do with these tuning issues, apart from scaling issues. When changing out the wire for decent wire, changing one vector, ie the wire only, the problem improves considerably. It seems reasonable to look at what garbage they made the wire out of in these pianos. The lowest of the low GP-1 sounds okay now, for a home based occasional player, and is acceptably stable.
As someone mentioned, even on these beasts, you get a yamaha action, which is a thoroughly acceptable and stable action. You also get the nasty hammers...but, hey you can't win'em all.

Thank you everyone for your input about the Yamaha GH1. It confirmed my thoughts and what others have told me.
I bought a brand new G1 Yamaha grand in 1973, for $2000 delivered, to replace my old Ludwig upright I inherited from Aunt Mary and moved it in a UHaul. It fit nicely and looked good in the space by the stone fireplace with the brass screen but I sold it after refinishing it and practicing my tuning trade on it with my mentor standing besides me. My payments on the Yamaha were half the price I payed for rent of the old stone country house overlooking the horse farm meadow. I kept doing restoration on the house and my landlord took my work price off the rent and finally sold the house to me just to get rid of it. I taught piano lessons on the Yamaha G1 for 20 years. It sat in the addition next to the wood stove. I built a barrier between the piano and the stove that heated the addition. I put in improved central heat in the old stone house but still used the fireplaces and the stove. In 2006 I sold the G1 for $6500 to a client. I just thought the GH1 would be the same or better than the G1 but I was wrong. It appears that the GH1's needs to be tuned every two to three months not once or twice a year. They look fine, need little regulation, but that's the most positive aspect about them. They just don't hold a tune very well despite piano saver installation.

When and why did Yamaha stop making the GH-1 grand, if they stopped at all?
What experiences have you had with a GH-1 in regards to stability and other factors?
Just askin'
