Todd, What is the gram weight resistance of the wippen flanges (and how many did you measure)? And the measured resistance for the jacks? Actual measurements can be superior to on-the-fly diagnostics.That pickiness aside, I worked for the local Wurlitzer company owned stores in the Boston area about 30 years ago, and I think careful use of jiffy key leads (maybe even cutting them in two & using half leads), positioned just far enough to have the keys return properly, can be an economically feasible (and easily reversible) measure for these beasts. That would be for the customer who says "just tune it, I don't want to spend money on 'customizing' this piano'." Well, they're got to pay for your time to make it at least minimally responsive. The better solution (and more $ for the customer) would be to shrink or lubricate the wippen flanges (while it is true that these keyboards were never really weighed off, I think the main problem is at the wippen assembly), rebush keys with better quality felt, etc. Or, more realistically, replacing it with a Yamaha U1, or a nice Kawai, etc. ...
