My M70 I dug out of storage

[Mikey]

New to the forum. Not a collector. I am the original owner of this awesome box. Bought it new in ‘80 or ‘81. Don’t remember.

My goal is to get it reconditioned. Needs a tuneup. Everything works, but audio is staticky. Switches/knobs sluggish. Belts need changing. Need antenna. Cleaning, etc.

My question is, how/where do you get parts? What should I be wary of? Need trustworthy sources. Looking for good people.

Thanks in advance for responses.

Welcome to the club.
'Do it yourself' is the best way to go.

There are YouTube videos available for complete overhaul of M70s.

Buy generic parts matching with the size from aliexpress as far as possible, to start with (e.g. belts).

Quite often the "staticky" or scratching sound can simply be eliminated by spraying DeOxit into the volume sliders and function switches. It's just a buildup of oxidization over time. Good luck restoring it!

Nice to see a vintage boomer in the hands of its original owner. I bet you had some great times with it!

Nice, you kept that in great shape.

Here are some examples of the videos on YouTube.

Place it on a soft towel or soft surface when you work on it to avoid scratches to your beautiful M70.
Make sure to take pictures as you dismantle, and this will guide you to put it all back together correctly.
Lots of patience and good planning is needed.

I would still screw this up. I rather pay someone that knows what they are doing, I was not born with dyi app. If some one is near md or del reach out

Im not trying to talk you into anything, but you could definitely solve your switch, static, and belt problem at less expense than the one way shipping to our closest member to you.
A can of Deoxit, maybe just a reconditioning for the belt, and it sounds like you’re golden. You can get a complete service manual for it. I may have got mine from here on the site, if I remember correctly.

I checked.
As a member, you can download the complete M70 owners manual AND service manual, both in .pdf format, from here on the site.
I tell everyone that repairing these units is a lot easier than you think. But that’s just me.
