To all,

In many postings I have read, the general advise is to not exceed about
1,000 turns on the secondary of disruptive TCs.  For example, Bert Pool's
excellent "Building Conventional Tesla Coils" states secondary coils should
be at least 400 turns, but no more than 1,000 turns.

Question:  If the length to diameter ratio is kept within reason (3-5:1),
why not use 1,200 or 1,500 turns?  At least this would lower the operating
frequency which is advantageous, even if secondary voltage doesn't increase
much.  Has someone done experiments which indicate about 1,000 turns is the
point of diminishing returns?

Thanks in advance for comments,

--Steve
