I have transformer 36V-0-36V from Technics SU-470 BSX.
Can i use it for any of this boards? Which board is best for this transformer?
1. 2pcs L10 200W+200W power amplifier kit DIY KIT-in Amplifier from Consumer Electronics on Aliexpress.com
2. 1pair LJM MX50 SE (100w+100w)Power amp kit Stero Amplifier kit DIY-in Amplifier from Consumer Electronics on Aliexpress.com
3. Assembled L20 VER7 Stero Audio power amplifier Kit DIY AMP channel 2.0 free shipping-in Amplifier from Consumer Electronics on Aliexpress.com
Thanks.

I would go for the bottom one!, but if you really want to build a better one, you can get many from this forum. there are pretty good ones and beside you will get all the help from here. I have try many but my favorite and still in my living room is this 2sk1058 2sk2221 irfp9240 mosfet amplifier schematic The M400 sounded better than my Bryston B60 (I sold it).
There is the matter of the OP wanting to use a 36-0-36V transformer and the resulting 50-54V DC rails.
The high voltage almost dictates a non-cheap amplifier. If price is the primary constraint, I think an Ebay
transistor amplifier kit or PCBs might be the only direct solution. You waste too much money sourcing hard-to-get
parts in small quantities and that's the reason for buying kits, even though the design or some parts may be ****.
If you still want a premium design and parts, it is going to be expensive, particularly if you DIY the whole project.

su 470 works wih VI limiters resulting high voltage rails providing enough headroom but still calculations dont work out
36+36 volt ac will be enough as voltage to create an amplifier of at least 100real watts at 8ohms ...still the specific trafo eventhough possible to produce the voltage hasn't got enough power to support them
even if you make or get a kit of 100 W power amplifier you will eventually produce almost 60 with danger and distortion ...
so sorry ..its a no go unless you design or get some amplifier that is designed to operate under the VI limiter principal and low power
Kind regards
