/diy/ - Do It Yourself

I savaged this sony amplifier and I've started cleaning the dust and that brown thing that stichs to the buttons. I'm also fixing some things like the speakers wire holder which is broken.

I wondered if the capacitors are still ok, this thing is old as fuck, maybe 10 years or so. The sound has some fuzzyness at the background sometimes and I wonder if it's normal

Also I wondered if there's a general procedure when savaging and reaconditioning this things.
