Re: [TCML] Quick and Cheap Toroid

Scott,

Those words were exactly what I wanted to hear. I can sleep easy now!
Worst case scenerio, I can add that second nst I have laying around and add
another slab of caps to my bank and see where I get with that. All without
making another secondary - Awesome!
Now, when you say "in general we in the TC community always make our
secondaries way bigger than they need to be, in my humble opinion...", were
you referring to the secondary circuit or the secondary coil? I can
probably guess you meant circuit, but just in case...
