Key Leveling System

[gordon stelter]

I have only serviced one PianoDisc, but have restored
many Ampico reproducers from the 20's. So I was
surprised to see that PianoDisc has merely a wire with
a rubber cap on it to push on the keys' undersides!
Would this not jab clean through in short order, and
gouge out the keybottom? It seems to me that a wide,
adjustable contact( to remove lost-motion) would be a
very nice improvement. (Improve playing at soft
levels, too! A common complaint of PianoDisc owners,
so I've heard.)
