OK, now that I finally tore apart the entire harp I have my inventory. It turns out that all of the yellow springs seem to have turned to a red-orange rust color with age, and the blue springs look more on the green side. So based on the 88-key spec for a 73, here's my supply:
Spring, Blue
#68 thru #80 Rear
I have 34 blue ones. This only requires...13?
Spring, Natural
#33 thru #68 Front & Rear
#68 thru #80 Front
I have 86 natural ones. Just enough to cover the 84 required by this one.
Spring, Yellow
#8 thru #32 Front & Rear
I have 28 springs that may have been yellow at one time. 50 is a hell of a lot more than 28. Why they would decide to use a
lighter spread of springs across the harp, I have no fucking clue. Too
much sustain???
I'm actually becoming more and more disturbed as I look at the harp piece by piece now, since I wasn't really paying attention when I first replaced the grommets almost 2 years ago now. One thing I noticed is that I still haven't replaced some of the grommets!!! Unfortunately I'm going through the remorse of "looking under the hood" after getting this shop piano from Major Key, which has at least 8 bad tines inside. By "bad" I mean old tines of theirs from test batches, none of which were ever successful as techs out there can tell you. I've already had to replace tine #35 in the midrange, along with the #5 long tine and tonebar assembly that were missing completely....
I think it's time to talk to Speakeasy about that Mark V in the box. I'm tired of all these headaches.
