Thanks Roger. The felt is flat. I did check alignment/tipping, and it looks real good. The damper head was slightly loose and turned a bit (rotated), so I tightened it a bit and straightened it. So perhaps it had been like that for a while, not seating well, and also establishing new/improper string marks. If it doesn't sound good when I go there in a couple weeks, I'll likely just replace it. They promised me all the pizza I can eat if I can fix it!
