Enables the power - on muting relay circuit. ( M1 & M2 ) Disassemble and clean the slide switch portion of the on-off switch.I still would like to know the function of M1 & M2

Maybe 4-6 small prongs on the underside need to be bent out to remove the slide switch from the mechanical lever.The switch appears to be held together with two rivets, am I seeing that correct?
The Red and White AC wires are soldered together at the same same exact point on the switch. So how can that switch the AC On/Off?
Does the dark side of the Moon always remain the same?There is no liquid in a PS cap that could leak out of it.
Input AC wires to the transformer looks to be brown and gray. You going to have to post a better photo than those in post 46 and 47.The Red and White AC wires are soldered together at the same same exact point on the switch. So how can that switch the AC On/Off?
Why would Yamaha do that?If white and red is tied together the switch is by-passed.
I would say Yamaha did not do that...Why would Yamaha do that?
