In my opinion it's best to leave it as is because it's fragile and no replacement parts are hard to find. Plus the readings once the needle is moving are accurate so I wouldn't play with it. \u003c\/p\u003e\n\u003cp\u003eNote: I had an extra plastic knob for the headphones selector switch. It's installed so you have a fully original M512.
