No sound from stereo
Hey all, I'm looking for some help as to why my old Technics SU-G75 amp isn't producing sound. All the settings are where they need to be, speaker button is on, volume is up, etc, etc. I removed the top to unit and it looks like some components overheated, see pic below. Looks like resistor 703 and 704 might be cooked? Don't know what would cause this. Could this be my problem? Is this a quick/ easy fix or am I better off retiring this old girl? Got it for Christmas about 20 years ago, I hate to get rid of it. Any help would be appreciated.
