My amplifier is broken, it allways light up the ‘safe’ led.
After looking up on the internet and checking all my cables and putting the amp to the minimum, I came to the conclusion maybe some of the output transistors failed to work.
These are all the pictures I took during the opening of the amp and disoldering of the broken transistors (with the multimeter set to Diode as a proof).
I will update this post with newer pictures of the replacement of the transistors, and I hope my amp will work again 
I replaced the two transistors, cleaned the board and the metal. Afterwards I putted some thermal grease on the transistors.
I putted back everything in place. Afterwards, it was time to clips the transistors. Put all screws back. This are the pictures:
I tested it and guess what … problem solved !
