-at- = @

this is so no programs that troll for emails off of forums get my email!

You can email me direct the total on Monday. then to arrange shipping yes?


Cores:


Excuse my ignorance, but I know C, R, E, and torroidal styles, Im not familiar with

W core... javascript:smilie('🙁') are the first images you shown W core? is W the same as E?



best regards

Hi Karl

Hi Karl.

I am look the dimentions of E(w) transformers amf toroidal.
The first a bigger than toroid.

I think You need think about.

In the first picture is OCM transfpormers and for Your power You will need OCM 0.6 = 600W or OCM 1 = 1 kVA. It's may need more cooper with small dimention toroid. In toroid I use 250% capacitance that more than big OCM. Weigh, dimentions, and power capacitance and price may be no interesting for you.

OCM I prefer for SE amps.

Transformer steel have not a big price and it's good for power cap.

Perfectly for me, I use 250-300% capacitance that work in linear indictance zone. Many factory use a maximum load. It's cleary - the taxes, worker fees, high-speed making, licemcing and other...
I think that that people use shot lnear corve zone(or transistor), why not look for inductance linear zone? Transformer is a enerator of curve, and this detail have distortion two (THD).

If You need a good (nice) looking - the OCM may be You will need to close by metal cap(box). ..Toroid the same...
The box - it's not a problem. Painting too.
I have all this.

Make the transformer for city light lamp or the amp - is a diferent think. Economy the money or dimentions.

Think about.

Dimentions

It's near 13 sm height,13sm - 10sm...

I don't see the problem to make it.


now i make the powewr transformers from toroid core.

I see many forum informations and diference opinion about.

But I have my own thinking now.

Toroids must have the caoasitanse and low Tesla ( Gaus).
If make two transformers with the same dimewntion toroid core
and ware
- it's will be the 500% capasitanse.

Many people afraid to use the toroid, it afraite the DC in inpit.
Many factories make the max level of minimal load.
It's the victory under the price, power
capability and dimention.

It's the same thing like with Philips
TDA1541
It'sa cheap element, but this element make give 20 bit, easy to make, have a low prise and with SONY filter (noise -110)
to overpaly the future high price brands.
-1db spectrum linearity and high oversampling rate.
PCM63 cost near
100 USD, the TDA some dollars...


Many people don't like TDA - thay don't knoe how to sweetch this scheme.

It's the same.
Toroid easy to make, I am make the core witha partners, and have a cheap cooper, easy to wirering and make a big cap.

For this dimention I am get more than from E transformers.

But look...

The 13cm X 13cm X 10cm is a good size for me.

I understand your thoughts about torroids, but they are not hard to get in the U.S.

To get E core or R core is very difficult. I've never even heard of W core until this

thread came up :xeye:


If the above size is for W- core let's see what the cost is 🙂

Have some idea ...

I have the idea to make a special transformer for
MC input transformer.

Interesting to know the price, which people readu to do for ultra-high-class.

I have toroid Co and Fe core.
m=120000 (like perm.)
Bmax (Co )= 0.45 T (4500 Gs)
Fe = 0.9 T (9000 Gs)

Diameter(tr.core) = near 35mm
Heght = near 1.5mm

With 120 w with double wiring 0db at real 100-120 Khz (Generator impedance near 75 Ohm wioth eqivalent Resistor in secondary and Ktr = 1:1).

May be Use mid pint for ground at secondary, and third isolated ware for ground to, for killing the negative capasitans.

Diameter of ware = 0.15 -0.2 mm

Have any idea?

It's will be near 60 USD.
but tell me about current in A in output for understanding the d of Ware.

It's will be

500 VA

1)120V
2) 27V (27-0-27)
3) 27V
4) 27V (27-0-27)
5) 27V

500VA/2 = 250VA/(27V*2) = 2,22 A
Click to expand...


I intend to fuse with a 2.15A slo blo fuse. Any more information you need?

Thank you for taking the time to sort this out 🙂

About payment

I am offer to look about payment.

The methods You can look at this page:
http://tube-fun.narod.ru/business1.html

I offer to make 50%.
I am start to make the transformer
after the transfering the payment.
When I winish finish, maximum time is the week for making -
I will give You know about, I will be know the weigh - and I will read to know the price for sending, I will give You know the second part and i will send it to You.

If You will possible to pay at one moment...

What do You think?
