Re: [TCML] 55 deg. primary

Hi Fritz; I did not disregard your advice for a larger toroid, I have been trying to come up with something. I do have a nice 8" with a 2" ring toroid that I will try, might be a little big tho! What I need now is a capacitor as one of my 2 [102mX30kv] doorknobs failed, I think I should have put some resistors in the mix. What do you think about maybe 5 of my 1.5 mfd X 2kv caps in series, I have 15 of them! Thanks Fritz, most advice is warmly accepted, but I am not sure about the guy that wants me to see if I can blow up my Caps to see if they will hold up!:-) Doug

May I suggest again, to build a larger toroid, for better match to the secondary coil -?  Retuning required, but you will be surprised of the progress. Much valuable, highly interesting informations you find on the many expert homepages ...
Best regards,  Fritz

<<I took the advice some of you gave to improve my small TC. I wound a new secondary, 7.5 inches with AWG26 on a 1.66 inch form, and raised it so it was above the bottom coil of the primary. I also had to add a few wraps to the primary.
If you watch the video you can see the improvement it made. You can also see that it shuts off abruptly, that is because one of the 2 [102MX30kv] caps in parallel decided to take a sabbatical! So, now I need a better suited Cap for this TC. Can someone advise me on one? Power supply for the coil is-6KV NST 30ma.
