Correct, I planned a 60 pF toroid.
- What kind of output are you getting with your 60 pF toroid?
- Is it a single streamer or not?
- Did you try with bigger/smaller toroids?
- How much power your coil uses?
The longest sparks I have got to date are 104". This is using a 14.4 kv
transformer at about 8 kva. I have only one 5" x 33" toroid and one 5" x 40"
and I use them both. I have not tried more but I think the system could drive
it as I get breakout at about one half power. Not a single streamer, more
like several at once.
