Hi everybody,
I got the 3 toroids today.
I also made my first openoffice spreadsheet. They are all visicalc and sort of the same.
So I saved it as a pdf and here it is.
2 pages
page 1 the biggo 3.38 Inches comparing the J type with the W type which is what we certainly have.
1-10 turns
page 2
I ordered a 2 1/2 inch that is thicker because of the math. I thought the results would be good and wow they are better. The J type is as good as the biggo W type and the W type on this is better than anything.
That is if higher inductance is the goal...and I believe it is.
This is not big enough to drop the spool into the middle but it is smaller as a toroid and could fit nicely into smaller items.

I saved this as a pdf. Please let me know if you are not able to see both pages.
Step one complete...
Thank you,

jeanna

Toroid dimensions. You may want to add this to your PDF. Personally, I find it easier to wind the larger diameter toroids.

EDIT: note dimensions are in cm.

Hi Jeanna . Is this what your were waiting for from cali ? And are you saying that they are as good as out big cores ? Please pm me with the part numbers and phone for them . and /or if everybody wants to pitch in we can do that . I can carry some on the site if need be . I would like 30 bucks worth at least .Also do they have BIg one also?

it is really TOOOOO  bad for this world ... 

i just wanted a little funding ...  now look  i take apart those rf amps ... 

now your in for it .... and this my friends is no joke... 

look what is inside 1 of thease amps ... thease are the small ones with out all the gold ...

high freq gold crystals .. big caps and tonnes of toroides ... 
and some really nice diodes..  mosfets the whole bit ...  its a smorg and im hungry like i have not eaten in a month ... 

like i said i really never want to take thease apart but now its tooooooo late....

i have silver wire ...  what does this mean ... ?   i also have 1000vdc caps and pulse amps ... duh!

lol  waite till you see thease puppys ... ac and DC ...  imagine ...  lol

i have 15 there bouts of thease ...  they send power over over the coax ... to this invertor ... it powers the invertor then proceeds to power up the trunk amp ....  yea .... they will BURN YOUR SOCKS OFF NOT JUST BLOW EM OFF... LOL

ist

the female gold connectors 2 grams of gold ..   the male 4 grams .. each amp has 4 female and up to 4 male .. plus all the gold on the boards ...  more than at least 1/2 ounce each ..  not the small amps ...  first 3 pics small amps ..

in the last pic there 3 female connectors you can see 6 grams 24k gold and the thick silver wires .. there many of them i think the center is gold core ...  pulse the silver collect on the gold ... 

wild nuts ... 

btw those 3 female connector you can see are worth about 120 cdn after i remove just the gold ...

6 grams x 20 bucks/g ...  and thats giveing it away ...

Using your inductance data, the relative permeability for the W material is 15,000.

Inductance in mH of a single coil on the 3.38" toroid is =  0.00777 x (number of turns squared)

(adding more coils on same toroid will change inductance of any coils already on toroid)

Thanks for taking the data.
