Can someone help to me at calculate a transformed choper?

[Nest]

Hi all, I'm new in this site, i'm spanish and I'm sorry my poor english.
I write this words at here by I don't know where at all site to do it .
I have a ultrasonic cleaning machine and a the last weekend my machine are broked.
I opened my device and I can see a ciruit of power broked, but I don't see a circuit of control what drive the transducers at 40KHz.
My idea is make a circuit of power with a microcontrolator to drive the transducers at 40KHz but I for make that I need make a transformer of the frecuency.
I have thought on make a transformer of frecuency of 40KHz at 230v/120V  at 130w.
My machine have two transducer at 60w 40KHz.

I need help to make a tranformer chopper in push pull configured.
If someone want and can  to explain to me how to calculate that transformer or if someone have a beter than idea....

Thanks at all

wiring transformers is anything but simple task

it is FAR WAY EASIER AND CHEAPER to find equivalent
in particular if your machine is Chinese.

Those trafos are very common in their apparatus
and just a dozen manufacturers really supply demand

Take note the codes and colors (yellow and green are two different
fabs) and codes can be found in their internet sales
