Hello everyone! I need some advice, I own a 1200va transformer with 45-0-45 outputs and I would like to use it to "son of zen" with about 20v per rail. I was thinking of a stabilized power supply. Is it a viable road? Thanks to everyone who will help me!

No, not unless you can turn it into a 22.5-0-22.5 transformer by re-connecting the primaries. Show a pic of your transformer for more inspiration.
Often transformers have two primaries which are normally connected in parallel, but instead if connected in series result in a half-VA transformer of half voltage (22.5-0-22.5V in your case). And that would rectify to about +/-29VDC bipolar rails, so you could make almost any typical Pass DIY amp (and not one like SoZ which needs a single rail).
Aaah Son of Zen, good memories.
Build it long time ago and used for few years with Lowthers.
I used variac followed by normal trafo and rectifiers and capacitors and so on.
That way i was starting it slowly without big current rush and i could operate it at any voltage for desired power, depending how hot i can tollerate it.
My suggestion is to get variac. That way you can use trafo you already have, or any other. Variac is a must for diyaudio builder anyway.
Good luck.

Great. I used sub bellow 100Hz because i used open baffle, you will see for youself if needed sub or not.
Why Son of Zen?
Why not F1J?

I chose son of zen for its simplicity. I like simple and minimalist things. I am not very experienced in electronics, my job and plumbing, but I have a great passion for high fidelity! My last work was these two Lowther TP1, they are very excited about the sound result of this double horn and I think it's the best solution for these fullrange drivers. they do not reach very low, but they are tremendously fast and at very high sound pressures there are never compressions or a sense of fatigue, the sound is always clear and free of distortions.

Oops that was incorrect, as SoZ also uses a bipolar supply.
Poke around on that transformer you have, as it appears terminals 2 and 3 are already connected in series...?
