The problem is that this was the first Gustav I work! The aftertouch of this piano is very irregular and they re some parts of the keyboard that doesn't have any aftertouch... The first problem I found was that the key bed was suspended only in 2 B. screws (the middle screws were floating)... I solve this problem and I checked the key leveling and it was ok (64 mm), white key depth was too depth ( 11mm, I use 10 mm), Hammer leveling were irregular but it was about 46 mm and there wasn t let off and I corrected it ( 2,5 mm)... even after this there wasn t aftertouch... and the bass section was very heavy... the sound was irregular but I ve seen worst... I had to put some lubricant in hammer flange center pin because the hammer movement was a little bit slow and heavy but I think this hammer flange center pin is not good Do some of you have any suggestion? Thank you Jos? Fernando Rocha</BLOCKQUOTE> Jose I have never heard of Gustav Lehmann, but the serial number might indicate it is a Samick product. However, from what you describe, it sounds like a problem a lot of 10 - 12 year old Young Chang pianos are having. The action brackets are made of a pot metal that actually gets bigger over time. The only solution is to replace them. If this is indeed a Young Chang product, you need to contact either Young Chang, or the company that represents Lehmann. I don't know who that is. Wim</HTML>
