If an analog instrument has been “transported” to a new location, then indeed
it should have the tuning gone over, as the Allen Bradley Tuning Ferrites will
have shifted. Banging the racks trays as you open or close them can also cause
the tuning to shift.
Tuning an art, and it can be learned through patience, and by someone who has
done it for decades. I have learned it well enough for analog instruments and
some pipe tuning. Though tuning mixtures (without the use of large Chenille
sticks or the Wicks Switch) still makes me want pull my hair out.
You need a proper tuning device for reference and someone knowledgeable enough
to tune the instrument so it is warm “live” and not sterile sounding from being
tuned too close to exact. Too much the other direction can really make one
cross their eyes.
The voicing Formant Controls are also something which should only be adjusted
by someone who has decades of pipe voicing experience and knows what real
wind-blown pipes sound like.
Side note:
My associate told me when the tonal finishing was done at Carnegie Hall the
first time around, Fred Tinker only had to hear a real pipe sound at Riverside
and then could easily duplicate it electronically.

the "flute keyer" is the 12 note extension for the pedals.
the "dual principal keyer" is for the 4' principal on the great and swell
the "pulse board" is for the festival trumpet and oboe. the adjustments on this
board interact and vary with the position of the expression pedal
the "puff" and "chiff" are 2 different things and are adjusted differently..
toward the bottom of the is R705 - this is the master level for the "air sounds"
output channel 4 is for the pedal. R867 (about 1/2 way down the board and to
the left of the trem controls) don't confuse this with the "expression" channel
4-which is the oboe level.
the speaker wire connections are "lever" type. Pull up on one side of the
little lever up and it should release the wire.
there are 7 "factory bias adjustment" pots. DO NOT adjust these.
I wouldn't try to adjust the tuning. they seldom get far enough out of tune to
warrant adjustment.
hope this helps out!
