Yeah, ok I wasnt very clear. I know that the secondary circuit is
physically isolated from the primary . Just a slip, I often think
of 'isolation transformer', when I think of 1:1 turns ratio trans
formers.:) My point was that a Tesla tank allready has high voltage RF
current, and that a 1:1 transformation or at least a low transformer
ratio between the primary and secondary could provide a much higher
base current to 'stimulate' the tertiary than the standard 1:10-20
ratio. Do you know the lowest voltage that could properly resonate
the tertiary?

Can you clarify the 'top node' more? I allways just called it the
'peak'. Ive allway thought that the 'peak' end of the resonator was
was very important ! :)
The top of a magnifier driver, as far as I know, can be imagined as
a 'supercharged earth', but in reality the whole secondary is referenced
to RF ground. So what Ime saying, is that if ratio of the voltage rises
between secondary and tertiary are increased, by decreasing the turns
ratio of the primary there will be the additional advantage of greater
potential difference between the ends of the resonator, at least so far
as the tertiary is closer to ground. How do you think a higher ratio
of voltage between the secondary and tertiary would effect tertiary Q?

Well, thats not to say that my off beat ideas are all the same as
yours! But then most of my off-beat ideas remain 'ideas':)or dont
work either! The big attraction of magnifiers to me, is that they kind
of ly just inside the border off off-beat science. The 'standard' Tesla coil
is a fascinating device and I'me sure to build many more and larger, but
its all pretty 'bugged out' now and but magnifiers arent ! :) I like the
'proven but not fully opimised' sort of feel. :)
>Do you mean aspect ratios? Ratios of turns (i.e. transformation
>ratios)? If you could be a bit more specific it would help.
Yep,turns ratio.
My current Magnifier secondary has an aspect ratio of about 1:1.3 with 120 turns
With the one Ime currenty ($lowly) peicing together, I might go a little
lower to 1:1. The most expensive part left to buy is the 3 18m rolls that
I have to buy. Something like $70 per roll! I guess thats $10-$20 less US.
A big $30 composting bin will make a nice form!
