The MMF-5 is back in action

[02audionoob]

For those who don't know...which I suppose might be everyone here except MC Chubby, my MMF-5 motor would eventually get hot after extended sessions and would whine. I thought perhaps it was something that could be resolved with oil or grease, but that never worked. Chubbs even sent me a penetrating lubricant to try, but no luck. So I call Roy Hall and ordered a new motor. Here's a photo essay of how I spent the morning...





















I'll post more when I get them uploaded.

OK...those last few were a bit gratuitous. Just getting in a little quality time with Ray Brown Trio and the Marantz.

That table with the glass platter is just stunning. The arm sorta looks like a fatter version of the arm on my MMF 2.1

I will like to make a platform like the one you table is resting on if you dont mind?

I'd be honored to have you make a platform like mine. We'll be platform brothers!

So terribly glad to see this thread.

My motor, on my MMF 5.1, after about 250 hours of use, started to make a horrible noise.

(Actually, it was doing it after 20 hours of use IF I used the clamp, but that's another story and I stopped using it.)

Roy says it's time to replace the motor. Seeing these photos let's me know just what I am getting into.

Not plug and play, but an afternoon project.

Good luck with your repair project. It's nice that Noob had all the pictures for you to check out before you decided to tackle the job. Are you going to go back to the clamp after the repairs. I still use mine. Jack

I dunno. A part of me (magic not science?) thinks the clamp is what messed up the motor in the first place!

[02audionoob]

Don't worry about the clamp. It can't mess up the motor.

Wow, nice work. Looks great. So no discernable wow/flutter or other issues? Did they send you instructions for installation?

[02audionoob]

Absolutely...there were very good instructions. Too bad they were written in Czech

Kidding aside...no instructions, printed materials or accessories of any kind were included. The original work was covered up in solder globs the size of English peas. I didn't know until I got them desoldered whether there was a big loop, a small hole or even no hole on those tabs. There's certainly no wow/flutter differences...it's a really simple motor. To hold steady speed I think you just need a heavy platter - and 3 or 4 pounds of glass gets it done.

Wonderful audio porn....do me a favor and measure the base of the hole where the arm screws into the base from left to right. If its the same as the base on mine, I can use an arm like the one on your MMF 5. The guy at Music Hall told me I would have to drill, but my table has a base like yours. On most of the MMF 2.1's that I saw the arm just sits on top of the base.

At the edge where the tonearm base drops into the deck it's a diameter of 70 mm.

Ok thanks.

Very nice job. How long did it take you? Love the platter on your table. Is that original?

I'd guess it must have taken about an hour. The hard part was the removal...especially the solder. That took twice as long as installing the motor. The solder was huge and I had trouble getting it wicked up.

That platter is indeed original. That's the one thing I like better about the 5 than the 5.1. Of course, with the 5.1 they upgraded the arm and changed from a 120V motor to a 16V motor (which allows use of the Speed Box), so the 5.1 definitely has its advantages.

I just have to look at this thread every time I boot up the computer....noob your pictures are very addicting.

[bob r]

and i agree i am also Addicted

[02audionoob]

That was my first modern turntable. Before that, all had been either Dual or 1970s/80s Japanese models...JVC, CEC, etc.

[bob r]

Thanks
i think my first TT was by Radio-shack and then i moved up to the Dual and then a B&O with a MMC 5 cart the B&O i still have but it no longer works but it did serve me well i also still have a brand new MMC 3 Cart for the B&O if anyone needs one

[02audionoob]

Then I should dig out this classic...




I like the way the Eroica cartridge looks on the MMF-5, in this oldie but goodie...

[poppachubby]

Yes the pics look super tasty. Where is the Marantz TT now?

[frenchmon]

Awesome... the Eroica cartridge just looks bold and dauntless...like its ready to track anything you throw at him. You still got the Rantz Deck? If you got a pic of it necked...cover off, post it. Those Rantzs are very nice looking.

[frenchmon]

Hey why dont every one who has a table post some pics....Poppa you game?

[02audionoob]

I couldn't justify having the Marantz 6300 with the MMF-5 sitting right there. It was only a matter of time. I should probably lie about this so no Marantz fans get teary-eyed but I parted out the 6300 on eBay. It had cosmetic problems and minor functional problems. I bought it for something like $74 (an auction with problems disclosed), got a few years use out it, and made probably $300 selling parts.
