Are you a diy newbie? Wait I think you are!

All of those are good amps, but you should get the one that has boards available and has well defined parts.

Among those amps SymAsym by MikeB takes the cake.

Check to see what transistors you can get in your country first. Make sure they are originals and not fakes. The NMOS 200 might work best for you, as the parts are easy to get and the MOSFETs required should be readily available as they are also often used in switchmode supplies.

The most important thing is that your transformer is suitable for the amplifier! And you're very lucky because the symasym is just much better than the rest, and it suits your transformer.

Also, I believe that Symasym be the best choice. I haven't built mine, but I intend to do so as soon as I get more good parts, coming from US.
For now, I would vote for DX BLAME ST, which has a very detailed and easy to follow project and advices, here: Greg's Web Site
and two threads in this forum, although these are not easy to follow and/or understand. Only go there if you are skilled. But Greg's site support is all you need to build the amp.
Your transformer is perfect for a two-channel version of this amp, which sounds great and is plain stable, with easily found parts.
Peace,
Max.
