Hey everyone,

I’m currently building a classic (tr)uSDX and I’m a bit confused about how to wind the toroid (FT37-43) T2.

For T1, it’s straightforward:

If it says something like “1T”, I just pass the wire through the core once → done.

But for T2, I’m seeing things like 21T and 3T and that’s where I got confused.

So my current understanding is:

- You wind them one after another using different wires

- Try to keep them close to each other but don’t cross over each other

Does that sound correct?

Or has someone a photo of the classic band bord that i can see how its done?

Would really appreciate some practical advice or photos from someone who has built one successfully 🙏
