Susan, Speaking of contaminated felt, I have had the misfortune recently to tune several G-457 Wurlitzers in a school. These pianos consistently tuned fairly easily up to through the agraffes, but turned into absolute "pigs" when I moved into the iron v-bar area! One movement of the pin would swing the pitch 5 cents on either side without settling anywhere near where you wanted to be! I treated felt, v-bar and front aliquots with Protec and stopped for lunch. When I came back they tuned like pussycats! The felt obviously does not allow the felt move easily at all! Friday I got into a small Young Chang grand (G-145?) and it looked identical to the Wurlitzers and had the same problems. One more pussycat! I love that stuff!
