Hi Gary,
Not to contradict the all knowing Wikipedia but, 45 TPI is #24 enameled. W'
is likely listing bare sizes.
With your other dimensions constant:
#24 will wind up at 85 uH -- 46 TPI
#23 will produce 72 uH -- 42 TPI
#22 will be 58 uH -- 37 TPI
Incidently, odd numbered wire sizes are very rare except in the realm of the
transformer/choke manufacturer.
Schematics, and other printed literature, are prone to errors especially
where numbers and letters are involved.
73 & Good afternoon,
