Hi Jeannie & Richard, Since I promised to not let this run long AND since you are the only two who've responded, I'll go ahead and tell you what I finally found. You're both wrong but good guesses, anyway. The pin from the damper tray which goes into a block on each end was just a little loose in the guide block on the treble end. I could hold the tray with my hand and hear a very slight noise & feel a very slight looseness. If I put a screwdriver between the tray and the block, twisted it a little to put a little side pressure on the tray, the noise would stop. After I removed the block and looked at it, it seemed that for some reason, the hole had enlarged a little in almost an oval shape where the pin enters the block and on kind of a sharp blow with the pedal, it would cause a wood rattle kind of noise. Besides the felt punching already there on each end, I noticed that on the bass end, there were a couple of center rail thick cardboard punchings. So I though, why not? I put a thick(ish) one in on the treble end reinstalled everything and the noise was gone. I don't know how long it'll last. I may have to do something with the block later but for the moment, everything is quiet. :-) Thanks for the posts and I hope this is just something you can file away in your little bag of tricks for future use.
