Re: [TCML] Stacking vs Large Diameter

Interesting information.  I have three toroids now; 21x6 23x7 and a 30x7.
Based on what you're saying it would probably be advantageous to me to run
the 21x6 close to the secondary, and the 7x30 above that?  When you say the
large toroid should be elevated above the second one you mean that they
should not be touching?
