Weird ringing - HELP!!

[Terry Jack]

Terry,

Thanks you for writing.

No electrical cords out the back.

The dampers do follw when I press on the strings.  I bought the boxed set of dampers from Schaff for the tri cords and made the bass dampers from bulk materials.

As I only have 7 years of experience I will quickly admit I hardly know everything. Hoping one of you folks can help me somehow. *smile*

  Is there an electrical cord leading out from the back of the piano? If so, unplug it. It is likely powering the bass damper force-field and holding them off the strings.

  Seriously though, do you have damper follow-through when you press on the strings? If you do, and nothing is holding the damper off the string, the damper felt should dampen the offending string as well as your finger. Something must be holding the damper felt off the string.

  Also, did you replace the damper felts with those little smidget-puffs that the supply houses sell? If so, that might be the sourse of after-ringing (although they should still work when pressed with a finger). What is the condition of the damper lever assembly - especially the springs?

  PS: Another option might be to try and glue a finger to each damper block. Don't know where you'd find that many though......

  And from a very recent thread:

  It is a good idea "to replace dampers on an old upright with ones that are longer". I highly recommend getting a copy of Bill Spurlock's paper on Vertical Damper Replacement http://www.spurlocktools.com/id36.htm .  Piano Forte Supply has 55 mm and 67 mm long upright bass dampers:  http://www.pianofortesupply.com/dampers1.html

  Yes, you could measure the spring tension with a spring gauge, but any old upright is likely to have very weak wires. Consider replacement - and it is often easier to replace the entire damper lever assembly.

  I guarantee you, you don't want to mess with upright dampers without Bill Spurlock's paper in front of you. Only $2.50 and worth hundreds easily.

    Thanks for the idea but I have checked it. I am guessing the problem is one of those very simple things staring me in the face and I can't see the obvious.
