[Phono-L] Edison tuning record

During house cleaning, I find that I've got an Edison tuning record (3342-B-5) ... I know I am being perfectly lazy in asking: what musical note is this ?

I am guessing it is A-440, which is a standard at least in modern times. Dan Kj- ediso...@verizon.net wrote:During house cleaning, I find that I've got an Edison tuning record (3342-B-5) ... I know I am being perfectly lazy in asking: what musical note is this ?

It is in the pitch of A 440. Supposed to be used with a pitch pipe. Bruce
