Jim,
Kapton insulated wire will work, but you'll have considerably less
inductance because of the fewer turns/inch. Stranded wire will also work
with little problem - the reduction in Q between solid and stranded
should not have any significant impact on your coil's performance. While
you might be able to "instrument" a reduced Q, you shouldn't see much
difference once the sparks are a flyin'.
Sounds like the 54xxx series DIPS are military spec
Transistor-Transistor Logic or a variant such as Schottky (STTL) or
Low-Power Schottky (LSTTL). While these are more tolerant of power
supply voltage variations and have a wider operating temperature range,
they are every bit as sensitive to EMI and Tesla Coil damage as their
industrial or commercial grade cousins.
Safe coilin' to you, Jim!
