Yamaha CP-70 hammer/damper repair Q

[soul]

Hey all,

I recently acquired a CP70 in pretty good shape. I just got a power supply today, plugged it in, sounds great! Its relatively in tune, not too bad at all. But it has 2 keys where the damper falls down immediately, so they wont sustain with key held (just a quick muted tone). (I can upload a video if it helps)

How involved is it to repair this? Seems like there are only a few parts involved. I'd appreciate any advice on how to do it or where to buy parts (or both).

p.s. Im also ISO legs and pedal for decent price

thx,
Steve

Looks like I found some legs and pedal. Could use some advice on fixing a couple of dampers that fall and mute the string immediately. Anyone have any insight how to repair/replace?

Here's the F key with broken hammer. Any ideas on what I need to repair/replace? Everything else is pretty clean, got some legs under it today

Seems the whole thing is flat.. I bought a tuning wrench on amazon and l got it plugged into Pro Tools with a chromatic tuner plugin. Gonna try and get it in line this week. Still looking for advice on the F damper that's clicking, I'll address it later. Looking forward to getting in tune and writing/recording on this baby

The hammer and damper both appear to be working. It sounds like either loose screws or loose glue joint(s) on some part on that key. A loose hammer head or hammer flange screw are the first 2 things I would check. I do not see the damper falling down right away. It seems to be staying up.

Be careful tuning that! They are very difficult to tune and very easy to break strings. If you ever break a bass string do NOT throw it out. You will need the old one to have a duplicate made.

That piano is very inharmonic. The bass especially is difficult to tune! You need to tune bass notes FLATTER than you expect, don't make them sharp or they may break. $$$ to replace bass strings.
