Dead Amp?

Hey,

 

I got an amp from a buddy because it didn't work. (Only hiss on the speakers. Worked fine before. (I heard it myself shen it was still working))

Today I planned on repairing it and it doesn't do anything (not even a light is on). I can hear the transformer, thats it.

 

It's an Marantz PM-54.

 

Attached are some photos of the insides. I don't see anything conspicuously.

 

P.s. I already changed the fuse. Also I changed the power plug so I can use an C13 cord.

 

Maybe somebody knows something

 

EDIT: I forgot to say it was standing around for about 1-2 years without me touching it. Some random dude on some german page said : "The capacitors need to charge, let it stay plugged in a while" (That was totally not my topic where I found this). Did this for like 3 hours and nothing happened.

 

Spoiler
