Count the number of beats flat at A4 and set it about 25% sharper than
it is flat.  10 beats flat, set it 2.5 beats sharp.  Stretch the octaves
a bit more going up to the top and in the bass.  The wider octaves going
up will compensate for greater overpull required in the treble and a
progressively flatter instrument as you add tension below.  The
overstretch in the bass will result in less overpull which the bass
requires.   Tune outward from the temperament octave A3:A4.  Expect to
do 2 rough passes before fine tuning.  ETD's are a lot easier.

How does one go about doing a pitch raise without the use of an ETD?  Is
it a whole lot more difficult to do?  How do you do it?
Thank you!
