Well, today me and the new parts have arrived, finally!
Replaced: U17 and IRF3415 (IRF6215 others were already replaced)
When connected, the LED lights to protect two seconds and shuts down.
The speaker produces a sound followed (ssssssssssshhhh) and when connected to the input audio sounds very softly.
Any ideas?

Sorry, Perry, but now, I'm not at my house, I'm at work, and even within two hours, do not go out.
Anyway, I think, last night when I tried it, yes, to disconnect, fell about 15 or 20v ... on the positive and negative high voltage.
Consumption at rest was two or three amps.
In the speaker output, had 0.9 v. ..

Well, I'm here with new information,
Q8 and Q25 replaced (I still have some in my closet)
This is what happens:
Protection Led two seconds and shuts down.
Positive and negative the meter, the audio output, 1.02 V
When you release the positive terminal of the battery, the meter mark: 19.70 ... 15.20 .... 11.80 ... 7.50 .... and to zero.
I dare not connect a speaker, because I have fear, it explodes again, a transistor.
weird, huh?

I have to check.
All resistors MOSFET gate of the audio section, I have replaced with new ones.
The originals were 25 ohm 1% tolerance.
And I've replaced are 24 ohm 1% tolerance.
Could this be the cause of failure?
When you say "virtually anything will work," what do you mean? I do not understand ...
