Jim:

If  you wish, drop me a line and I will send you a complimentary large
flyback for your PCB experiments.  Our flybacks are wound with a 70 turn
primary to switch 120 VAC through MOSFETs.  The secondary is 4,200 turns of
#42 AWG.

These units were modeled after some old Zenith color TV HV flybacks that
operated at 25 kV rectified output.  They are silicone encapsulated.

Just provide me your address and I will ship you one for experiments.
