Default How does this class A look?

I have asked from an another forum too but let's ask more.. So is there anything in this circuit to get it "optimized" better? It looks very simple, just like something I have been looking for. Which FETs would be best (and inexpensive and easiest to get and..) for this amp

I'm going a little confused 'cos I'm trying to decide what to build, LM3886/3875 or LM1875 or this class A amp. Class A would produce "enough" heat to try water cooling, which I also have been planning for a long time..

Hi,
try IRF540 or IRFZ44.
These are cheap and strong.
Let us all know if it works good.

I contacted the designer of the circuit and got suitable parts for it. I'm going to use IRFPC50s. I'll make two of 'em for stereo use.

Here's a diagram version 1. I try to get the interferences low by putting the trafo as far it's possible from the amp board. All suggestions are still welcome how I should place all the things inside the case (which is going to be full 43cm wide).
