I have one brushed aluminium toroid and have never used it.I don't try to calculate size any more. Bigger is better. I have used all sorts of bizarre types including a Red Alert reproduction multi level one.
On the other hand all my home coils have a rotating rod/breakout point.So if they don't affect performance, are OK in museum and public performance and are in use on TC's of all sizes then it's just a vanity thing to use the brushed Al one at great expense.
Just my 2 cents (Australian) worth (and likely to be controversial). Peter tesladownunder.com -------------------------------------------------- From: "Scott Bogard" <sdbogard@xxxxxxxxx> Sent: Wednesday, March 13, 2013 7:34 PM

Out with the old and in with the new! All butthe primary coil actually. I can double my nst amperage and cap bank capacitance - if it need be. As well as the secondary coil. However if it 'can' work without those changes then by all means let me know, but from what I can tell I'll need to up the anty system wide. Brandon
