[pianotech] Faulty sostenuto tab

Lim,

I just worked on an S from 2003 that had about 30 tab springs that seemed to be missing.
Actually they were not missing. The end of the spring that you see on the good ones had slipped to the side.
With a thin bent tool I was able to fish out the end and snap it onto the front. Because I had to do 30 of them, I quickly deveoped
a technique to find the end and snap it to the front.

I thought I would never need the technique again. Maybe there is a virus going around!

Hope this helps.

hi
I thought this 'D' model tab is sluggish initially but couldn't feel the spring under the tab. Used a mirror and light but still no spring. What could have happen and how can I repair it? It doesn't seem to have individual damper lever flange screws.
Thanks!
Lim
