Those of you who want to join in on the rounded core trafo group buy.



Please send me a mail to me through the forum mail, stating the number of trafo's you want to buy.

At this point I think pretty much anybody with interest in this have noticed the option, so in order to speed things up to avoid hitting the xmas holidays during the manufacturing, I would like to move the deadline forward to this sunday 28th. of November at midnight CET.

If possible it would be ideal to get things going even sooner, so please don't postpone anything unnessecerely.

Cheers

Magura

Question 2*18V O-core 1000VA group buy

Hi Magura,
What is the percentage regulation of said transformer?
Any other technical specs available like Hipot reading, primary to secondary capacitance etc.?

I have none of those figures, as this is not a standard trafo, so the exact data is to be measured after we have the first batch.

Hi Magura, Let me then ask: is the secondary winding on top of the primary or on a different section of the O-Core such as in the R-Core in the attached picture?
Do you have a picture of your O-Core?

Hi Elso.

Let me start out by stating that this reply is written with a smile

As I wrote earlier.....this is not a standard trafo and have not been made before......now Sherlock Holmes would conclude that a picture of a non existing trafo would be somewhat hard to find

The secondaries are on top of the primaries.

Besides the fact that the trafo in question is a rounded toroidal, not O-core, then you are right. That would be something like what it will look like. The wire for the secondaries is though somewhat bigger gauge, 3.5mm.

The pic you have found is from the website that actually caused the initiation of this groupbuy. They advertise a great looking trafo, but the reality is something of very low quality. I ordered 2 trafo's from them and those were returned. Now all that is left of those is the battle with the company to settle a refund, as what they sell and what they advertise has little to do with each other. See pic.

I guess you can find a part the answer to why you got no reply in the above post.

As things are now he is facing a fraud charge in the nearest future if he dos not give me a full refund, as he asked me to return the trafos, and so I did return them.
