In working with the Family Theater transcriptions, I kept a separate valid file of the opening bars of the beginning music to use as a double check. I found more than once that I had to change the pitch of the recording I was working on due to variances in turntables and dubs.

Beware that in some cases the NBC chimes may have been dubbed from

no longer sound G/E/C exactly. I've encountered cases where they were very 
far off.
