1.Motherboard has a switch probably for two kinds of fuses(one for 110V, other for 220V which is smaller).
3. 3 wires are  positive voltage, negative, and ground, other two are AC mains. That way most if not all modern poweramps are designed.
Your transformer is standard EI76 x 46 which is about 70W of continous power.

Thanks. The power requirements are 300W actually, I attached another pic above. And there are 2 types of fuses indeed.

According to the repair shop the amp is fine, only the transformer burned. Not sure how they figured that out, maybe they are just trying to have me buy the transformer only to realize that the whole thing is broken. It would be great if you could help us, cause we got puzzled by a few facts when opening up the amp:

1. The AC input wires (black&white) don't go straight into the transformer, but onto the motherboard first, where something happens to the current most probably, cause then we have 3 wires (red, yellow, black) going out of the motherboard and into the transformer. First question: what does the motherboard do to the current and why 3 wires instead of 2?

2. The AC connector going out of the motherboard and into the transformer has 2 positions, depending on the AC input (110V or 220V). Which raises another question: what if the 2 transformer types have different specs and the 110V one cannot be used to clone a 220V transformer?

3. The transformer has 5 output wires (2 blue, 2 brown, 1 black), so there are several outputs there. Is it possible to figure them out at all?

My uncle says there are several standards for measuring E&I, I wasn't sure which one, so I'm sending a pic with all the measurements there are.

Thanks

I wish we were back in the old days when repairing meant more than just replacing a board or a transformer. I will not pay 160 EUR for a transformer when the whole amp cost me $350 two years ago. The whole thing doesn't worth more than a hundred bucks. So I'll just have to rely on my uncle's expertize.  Make it or break it.

Hi Zappacat, you should start learning the language of the future: Chinese.
I´m starting to do so.

Meanwhile: the 1X-5730-04H0 is :
名称：X＇FORMER I/P:100/120VAC 50/60Hz O/P:15.2VAC x 2/7.
...
The 1X-6636-02H0 is:
名称：X＇FORMER I/P:100/120VAC 50/60Hz O/P:16.3VAC x 2/7.

They both are made by Jetronics and cost Yen 17 and 27 respectively.
The 0814 code means Year2008, Week 14 (mid March).

Hi!

Reactivating this old topic. Do you happen to have the specs for the Line6 Spider III 75W as well? I would need both for the 110V and the 220V.

The story: I bought the amp in North America, then moved to Europe and plugged it in, being mislead by a sticker that was suggesting it's a dual transformer. Then boom! I took the amp to a Line6 dealer and a replacement transformer (220V) costs 160 EUR. Of course they wouldn't give me the transformer specs.

Then I tried to find this info on the Jetronics page, without success. I sent them an e-mail and got this strange answer:

Thank you for your inquiry! We would like to inform you we have the power transformer for Line 6 Spider III HD75. Could you please provide the authorization of Line 6 to use this transformer in your products for our reference?

Best regards,

Now my uncle claims he is able to calculate the output based on the size of the core and the number of the loops in the coil and then rewire the transformer. Not that I don't trust my uncle, but I would like to get some kind of confirmation on the actual specs before I let him dismember the transformer

Thanks!
