Hello everyone!
I would like before trying to build trafo (non-toroidal) for ESL panels.
I need any information you want to let me know.
Can you help me understand how to do it?
Thank you all.

At first you need to collect all relevant data, this is:
1.-Impedance ratio, sec to pri or vice versa.
2.- Minimum frequency to be transformer with no too important loose/distortion.
3.- The maximum size allowable.-
4.- Power amount to be transferred.-
5.- The iron quality available.-
6.- Number of windings (in case you have more than two) for, feedback, for example.
There are several approach to the final device, but imho a great work is done in the Langford-Smith's Radiotron available in the web in pdf, and a work from an Argentine professor called Ladislao Koros from whom there is no work available in the net.

I forgot in the above list, the input voltage, as it will define the primary turns in the windings. Sorry‼.
Key parameters are
ESL capacitance (lower much better, favours segmented designs)
amplifier OP voltage
low frequency cutoff
voltage step up ratio
amplifier/speaker lead OP inductance and resistance (much lower better)
