DC units do not address pin blocks in grand pianos. I had a customer with a 5 year old Kawai RX series with a DC unit installed and had loose tuning pins. I read 15% humidity in his home. I instructed him to purchase a humidifier immediately. With 6 weeks at 40% humidity the tuning pin were back to normal tightness. I got it back in tune and now it stays in tune. I have found that DC units do a fairly good job in upright piano.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Al Guecia<BR></FONT><FONT face=Arial></FONT></DIV> <DIV><FONT face=Arial></FONT><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>----- Original Message ----- </FONT> <DIV><FONT face=Arial>From: "Prof. Euphonious Thump" <</FONT><A href="mailto:lclgcnp@yahoo.com"><FONT face=Arial>lclgcnp@yahoo.com</FONT></A><FONT face=Arial>></FONT></DIV> <DIV><FONT face=Arial>To: "Pianotech List" <</FONT><A href="mailto:pianotech@ptg.org"><FONT face=Arial>pianotech@ptg.org</FONT></A><FONT face=Arial>></FONT></DIV> <DIV><FONT face=Arial>Sent: Sunday, February 17, 2008 5:21 PM</FONT></DIV> <DIV><FONT face=Arial>Subject: Whole room humidity control better than Dampp Chaser.
