[pianotech] 300 cent pitch raise - correction

[Paul T Williams]

Probably should have left it down to at least A-435.  Nice nothing else 
popped...like the plate!  Was there a reason to get to A-440? It may be 
structurally healthier to get it back down to at least 435.  I'm not sure 
if anything was designed in those days to handle 440 tension.  big 
difference.

Re: [pianotech] 300 cent pitch raise - correction



After thinking about this for awhile, the 300 cent pitch raise was on an
antique piano - Collard & Collard - 1886 - that to my knowledge and the
customers' knowledge had never tuned.

The customer initially bought it as a show piano then after I got the
piano operational - which had to fabricate several new action parts - he
decided he wanted to play it.

So, I seem to remember doing a "chip" tuning with the Cybertuner with
whatever the lowest tuning pitch it has - A335 ?

Once I found out that most of the bass strings were popping, I ordered
new bass strings, put them on and tuned again - this time at A440.

Amazingly, nothing else popped.
