Amplificador de 60w

Figure 1 - The 60W MosFet Amplifier Schematic
And here is the PCB and the component Layout (fig.2 ).
Figure 2 - The PCB and Component Layout
With a little modification, and after burning out 8 transistors, I've reached the best output signal.
In a short time, I'll put here the oscilloscope traces.
As an suggestion of Rod Elliot, I've changed the output transistors, as seen in fig.3.

Figure 3 - Other output transistors
This give another output waveform, more aproximate to the real sinusoid.
The audio signal listened is softer in higher frequencies.
The power suplly is made by a simple toroidal transformer with an output at least of 3 Amp in 2x22V.
The filter caps must be at least 10.000uF for each line.
