Another time-consuming but deeply rewarding home repair. I love this amp far too much to replace it, and there’s really no excuse when there’s a detailed YouTube video of a Turkish chap repairing the very same 44-year-old Technics amplifier. I came close to despair with the input switches, but I bloody did it.

@colly also I have three of these marantz devices to do this with.
When I have “the time” to address it.

@Luke Gorgeous, love a bit of Marantz (from afar, never owned any) and always chrome for me. For reference, this is the video I followed — outstanding stuff, except he never properly showed how to refit the hairline spring to the switch bar and I nearly lost my mind and hate him for that. https://youtu.be/KR3PuaE86Xk?si=eN6GRwzNTTDrwnqq&t=17

@colly hahahah! Will watch. Thanks, Simon.
Gotta refurb my pots.

Edit: wow, he did a lot. Reassembled the pot too fast hahah. And those selector switches are quite a bit more complicated than keeb switches. Wow.
Also, might as well replace the forty year old power cord with new wire.
