Good news. I hope people do not abuse their offer of free samples. The companies are in business to sell products not to give them away. If they get too many requests they will stop doing it. Since you are on speaking terms with them, please ask who the local distributor is in your area and what the cost of the toroids are in small quantities. That will make them happy and let us know if Gadget, or someone else, can stock the parts for sale when they stop giving out free samples. You might also explain that the seller who was selling these is no longer stocking them.

I agree.  Good post.  I did try to contact a distributor near me first but their website also asked me to fill out a request for quote and had no listed prices.  Perhaps I should call them.  We do need a good place to buy these from on a reliable basis.  I would have been happy to purchase these and I will do so in the future.  I am just glad they still have the ones that you indicated we should use.

I felt funny asking for 4 of these not knowing what they might actually sell for.  I am sure it is much more than the $3.50 from All electronics. (at least in these quantities)

Thanks,

Bill

Hi all,
I have just been talking with a distributor.
The prices are from 2 cents to 2 dollars!!
I said, just a range because I have no idea and that was the answer.

So, I also said I wanted a sample range so I could try out a variety of sizes and ty[es and permeabilities etc.

All that will be following soon.
Also their minimum order was/ is $30.

Once we can figure the best sizes and types, we can order a supply and make someone have a good business!

I agree too.
You already saw my post that says these sell for anywhere from 2 cents to 2 dollars, and the person had some idea of the item because I gave the item number.

I also found out that the purpose for the paint is to keep the temperature down in the toroid.

I do not need that.
If I get heat, it will be at the ends of the wires in the form of a heater!

$30 seems a high minimum, but once we know what we want it won't be too bad.

I am thinking if I can extend/apply all the work I have done so far in the' multiple secondaries' project to this bigger item, then it SHOULD be possible to have one lamp unit in each room that turns on all the other lamps in the same room. We will see about that, but it is a very practical application.
AND, if anyone here wants to get involved with this project with me, I again invite collaborators.

thank you,

jeanna
