Hi everyone !
I have a Marantz 2270 that i got from my granfather. The problem is that maybe i got it too soon, like 10 years ago when i was 16 y o. At that time i had no idea about anything on electronics and plugged my bass guitar directly into the "dubbing in" input. That worked during a while but then some smoke when out from the amp and now the amp doesn't work anymore. I finally decided to open it and try to fix it !
The problem is that i'm not competent enough in electronics to find by myself where the problem comes from. When i switch it on, only the panel's light works, and i do not here the speaker protection relay's familiar click anymore. The headphones output doesn't work neither. I do not see any component that looks burnt.
I have scanned the schematic and the functionnal block diagram :

Thanx in advance for your eventual help.
Have a nice we !
