Is the winding controller setting the speed of both motors?

Yes The winder do use one motor for winding and one for guiding the wire, because I go to wind a signal transformer who is very small and thin wire I go use this, busy now with biulding it, maybe it is even usable with bigger stepper for winding to make output trafo,s.

I use a core special for signal transformers, it get to 5 Henry multilayer, this can only with that winder, the program and electronics I do not now yet if it works oke, there are also versions on usb and pc.

with the guid motor I can use very thin wire, pause it etc.

Kees, be sure that you wind for much more than 5 Henry.
I guess your reference is 600 ohm (divided by 2pi.F), but this way the transformer will have very little input signal capacity (saturation); go for something like 150H to present a ~ 20k AC load; that's doable on your core with thin wire.
(Sorry Tony to break in a little here....)

I have look here and see that 5 Henry is used there in a manufactored one, I do now output transformers for tube has high inductance like you mention, I think 150 H do not fit on that transformer.

Transformers for Audio

I think to start a new thread because we hijack Tony.
