---------------------- multipart/alternative attachment Hi Dave! I've seen a lot o' interesting stuff with the disclaviers. One of the=20 advantages of working for a Yamaha dealer! The regulation issue is pretty simple: uprights (MX80) can and should=20 be regulated just as you would a normal piano. On one of these that's=20 playing continuously the regulation should probably be done once every=20= year or two. The regulation, as you've figured, has nothing to do with the piano=20 regulation. There are felt punchings on top of the solenoids that do=20 wear out and need to be replaced. Yamaha has them. It's a relatively=20 easy fix to take the keys out, the metal cover off and replace the=20 felts and that should cure the problem for some time to come. will wickham On Apr 8, 2004, at 12:05 AM, Piannaman@aol.com wrote: > Howdy folks, > > I got a call to tune a Yamaha MX80 with Disklavier that plays=20 > continuously in a Chinese restaurant. =A0I tuned it last year, and it=20= > had no real problems to speak of. =A0When I walked in, my contact told=20= > me that it "makes a real funny noise, like it's hitting on wood." =A0I=20= > tuned it(it was at pitch, and in remarkably good tune all things=20 > considered), and noticed alot of bubbling hammers. =A0Keydip was shy=20= > almost 2 mm from the factory spec of 10 mm. > > I am not that familiar with the workings of these players. =A0In a=20 > standard piano, I'd either shim the balance rail or take out paper or=20= > cardboard punchings from the front rail to increase aftertouch. =A0What=20= > stopped me from doing that was the square metal tab that protrudes=20 > from the bottom of the key and slips into a sensor slot on the keybed.=20= > =A0I have no desire to alter the depth of travel and possibly alter = the=20 > elecronic end of the instrument. =A0Does anyone have experience with=20= > this problem with these instruments? > > I never did find the woody sound while tuning the piano, but as soon=20= > as I turned on the player mechanism, there it was, a really loud,=20 > obnoxious clack everytime F4 was played. =A0It didn't take long to=20 > figure out that it was the solenoid knocking against the metal that=20 > covers all of the solenoids. =A0I pulled up on it manually, and it was=20= > noisy; it was the only solenoid that made the noise. =A0I'm assuming=20= > that a grommet or rubber washer of some sort is missing, but I did not=20= > have time to take out all of the keys, remove the cover, and find out=20= > what was amiss. =A0Nor did I have whatever part I might have needed. > > I noticed how much the keys were lifted above the balance rail by the=20= > solenoids, so I did a quick fix and lowered the adjustable metal=20 > key-stop rail to limit the travel to the point where the solenoid=20 > would not max out. =A0I know this is probably a short term solution. = =A0I=20 > would certainly appreciate any advice, information, and general wisdom=20= > about either or both of these problems. > > I have not called Yamaha yet, but are they likely to be forthcoming=20 > with a tech manual on this, or is there one online somewhere that=20 > someone could direct me towards? > > Thanks in advance, > > Dave Stahl= ---------------------- multipart/alternative attachment A non-text attachment was scrubbed...
