KA-3700 Repair

Had this amp given to us a while back and I used it for a few years, then used it as a garage stereo, my dad used it one day and it blew/stopped working.

I'd like to get it working again instead of replacing it, but haven't had any experience with much before. I have soldering equipment and have soldered before, with basic electronic knowledge from engineering study.

I think ill try downloading the manual and replacing the fuses with correct ones, looks like one has blown. If this doesnt fix the problem, does anyone have suggestions on what to check next?

Do I need a good multimeter to test components, or should I just try replacing the probable faulty components? Thanks :)
