I'll have to dig through the files in school for the B - it was the other tech here who actually did the work. We did discuss it back and fort a lot though....

The D is 1999. The B has been rebuilt so many times with such a mishmash of parts that the year of manufacture is basically irrelevant... > It's true that there was a period when the tails were extremely > short, but that's not too recent, in my experience.

Those Steinway backcheck wires are pressure fit on both ends - you don't have threads on which you could "raise" the backchecks... >As an experiment, it falls short of completely explaining the issue, >since there are undoubtedly differences in a number of >characteristics between the two brands. Can you look at the two >side by side and compare them? I did. The Tokiwa backchecks look just like the old Steinway backchecks - both in length and in shape (longer and fatter/rounder at the top than the current Steinway backcheck). See, I had an extra one floating around, and so I put it on one of the worst-checking notes on the D - and presto, all the problems went away. That's good enough for me. It was also good enough for the client - he paid for the replacement of all of them, and loves the results. And if Wim is willing - I'll be glad to send him one of my 2 leftover Tokiwa backchecks to try out... And having prepped one hell of a lot of Steinway grands at two Steinway dealers (Boston and San Francisco) over the years, I'm really not interested in screwing around with Steinway backchecks any more than I absolutely have to - they gave me enough grey hairs already...
