Work of art right there. Love the look of that T1. I am looking for one that has pins you can set into a PC board instead of wires. Is it only the core type that matters?

Is it only the core type that matters? not sure what are you talking about? T1 ? it's original bobbin (which you can order from EPCOS) comes with pins for PCB. you can use it, but it has no sections - you'll be limited with layer-by-layer winding method, with insulation tape after each layer, which significantly limits possible number of turns. that is not good for push-pull (2 mosfets) circuit type.

Ok. I understand that. Where can you buy sectional bobbins? Didnt you have yours custom made via 3D printer?

thats still not a good choice, because for rm6 sections are too wide. believe my experience - it will not last long. However, winding layer-by-layer bobins is not impossible, if you will pick a bigger pot core like P22

What is the difference between a RM5 and RM6? How did you get by with making the one you did here?
I’ve wound transformers before. But not like this.

But not like this. difference is the core size I take it the 5 is smaller? They aren't expensive. I might just grab both. (The 6 and the pot you posted) I do REALLY appreciate all your input. Read your blog yesterday. Liked the article on the Nova.

I have a small transformer that came with one if the cheaper guns I have. Going to gut it and practice.

Ok, Google’s language translation often read like a horribly written Mad-Lib.
To make sure I’m up on the current procedure, the first inverter transformer has a primary of 19AWG, and a secondary of 37AWG?
Just so you know I usually do a day or more of searching before I force myself to come here and ask. I really hate bothering others..
And does anyone here know about Litz wire? I’d like to use that as my primary but I’m not sure what size would equate to 19AWG. Or is it choosen by frequency?

As a matter of fact I’m pretty sure it was a post Gary made as far as turning me onto Litz wire.

Or is it choosen by frequency? not sure, what design are you talking about ? anyway, lits wire has no effect in our area of application. it's used on MUCH higher frequencies AND currents.
