I would always make an interstage for myself and i would also take a tube with a lower Ri to reduce the amount of windings, but, it depends also how large the swing needs to be. Other solutions are bigger cores.

Hi m.mug.praedinius,
> > I consider in case of a swing of 110Vrms 4000 windings as a minimum. If you need more swing more windings are needed.
Not quite understand why you said more output voltage then more winding is needed. What factor would block the the ourltput voltage ?
More swing means that the AC flux will be bigger. There are limitations at the magnetic field because of the pre-magnetisation and also at the maximum flux.
And with more turns you can use a bigger airgap to reduce flux
Hi m.mug,
A side issue that need your expertise
An interstage, M6 silicon steel EI76 40mm lamination, 2700T primary, 4000T secondary
When the secondary reaching around 150V rms (No DC at that moment)，the waveform seemed deformed, becoming like saw waveform(see attached photo)，what could be the cause?
Btw, it's not an interstage on the photo
Way to less information to give a reasonable answer, sorry.
