Wayne's number at the Yamaha Atelier in NYC is 212-339-0032.I had an alignment done on my picc (which is 15 trs old) and it worked wonders for me. The slotting is consistent top to bottom as is the pitch.The high concert A on the A side was sharp as was the F#,problem solved with the valve alignment and cleaning,plus Wayne and the whole Yamaha staff are great people.
