HI ,i just finished a coil almost identical to yours.my secondary is 3 by 15 wound with 24awg.i think you should have had a better ratio for your secondary.its too long for its diameter.your primary needs more tubing.get a 50ft roll.it gives about 15 turns.be careful when forming the primary coil.it can be bothersome.the caps need to be more like .005. use a better capacitor.salts are annoyimg.thats why im looking at mmc now. matt
