The main reason for opening this thread is first its making me enjoy spinning my lps and very little info availible on this cart,and i am having a great time spinning some lps on this excelent IMHO cart.
Its been spinning for some 30/40 hours on my Kenwood KD 990 TT and it has blended into a one of the carts that will not leave my stable.
Tracking at 2.1gms this cart tracks very well,the tapered cantilever makes this cart sing much to my liking especially on the double bass drum pounding for heavy metal music.
It has an excelent thunderous tight bass,that surports the whole sound.
Soundstage is centered and stereo effect pronounced.
Highs are NOT splashy and sound very real that is not easy to get from other carts i have.
I am enjoying this cart very much.

INF wanted please (manufacturer,stylus options,etc) dont be shy!!


Here are the specs for the OS 101 /201 / 301 cartridges

Neat how it uses an unusually small spherical tip .5mil, too bad the specs dont list the inductance. often wondered what happened to Osawa, cartridge resembles a Nagaoka in appearance.
 
Well i really would like to know who made this cart??
the research i made gives me hints of Nagatron ,Nagaoka but nothing conclusive.
here are some other carts and stylus that seem to be the same maybe this will help to put some more information on this cart.

Thks for your help on this research Balifly i had googled up that inf.
I think you have a Nagaoka MP11 can you or someone else tell me if this cart resembles the MP 11 in any way?
I did find this very similar fotos of a Unitra Fonica with Tenorel stylus

I have a Osawa OS200mp on a Dual 1257 that I have not been able to find any info about. It is a great sounding cartridge. I hope I can find a stylus for it. I tried a few months back and the only thing I could find was stylus for the os101. Good luck with yours.

I too have an Osawa-branded Nagaoka OS-200MP.

The stylus you want is the N-200MP. Actually, the one you really want is the N-300MP with the carbon fiber cantilever.

The rumor is that Nagaoka was a great admirer of Pritchard's ADC designs. Sure enough, some of their stuff (eg, the OS-101) strongly resembles ADC's 1969-71 models. I believe Osawa was simply the name of the original importer/distributor. UPDATE: I was wrong! Yazuo Osawa's story is much more interesting than that.

Thanks for posting the links and the interesting information.

On a related matter, I have a Nagatrone 185E with out a stylus.

I think I have found a new unused one.

Any information about this company would be very welcome! :thmbsp:

705-D# is the Pfanstiehl stylus index number for the 185E. So far, all I can find are conicals.
Nagatron was one of Nagaoka's several acknowledged cartridge brands, one presumably meant for the US/NA market. IMS, Nagaoka, Jewel Tone and Osawa are the others I know of. Nagaoka also did covert OEM work for many other far more famous (in the NA market, at least) brands.

Well this cart is a keeper, great for doublebass drums and heavy metal.
So do you guys think the Nagaoka MP 100 stylus will fit this cart??as well.
 
I have a 101 and it is my favorite cart for some reason. I can't bring myself to get rid of it, even though I have it on a turntable I hardly ever use. It just sounds great to me. That's always subjective, but it is true.

Osawa made two lines of carts - the MP and OS, as I recall. The OS is the lower end one (yours), but it is a lot easier to get needles for those and impossible for the higher end MP ones unless you want to dump a ton of cash. They were related to Nagaoka somehow as a company.

The MP stuff will not fit this, so you are lucky in that those are pricey and hard to find, and that you can find a replacement sub needle fairly easily. The 101 used a .5 spherical. I sub the Sansui SN28 needles in mine. They are conical .7, but sound fine. You can get those off of ebay cheap enough. The jobber number is 698-d7. Every one I have found was great . I suppose if you found a 698-de you would find the eliptical 201/301 needle, and the fit is the same. In theory if you found a 698-d3 you could play 78 rpms!
 
eb2jim Thk you for some objective information.So is the MP the same cart internally and uses the same stylus as the Nagaoka MP 100/110?
The OS series is also Made buy Nagaoka?? but is a different cart altogether and uses a stylus that fits only the Os series?
 
I don't believe the MP is the same internally as the OS. They are two different animals. The Nagaoka MP is the same as the Osawa MP from what I have found. I have a couple of the Osawa MP carts in my junk pile. I just can't be bothered buying a needle for them. They don't look like the OS cartridges.

I don't know if the OS stuff was even made by Osawa or Nagaoka. That series seems to have been designed to use the Sansui styli, so it may be an original cartridge designed to use a fairly easy to source needle, or it could just be a re-badged cartridge made by someone else. It may actually be a variant of the Sansui ST28 cartridge. I don't know specifically, and have no Sansui cartridge to compare it with. But it is a well-made and nice sounding cartridge for sure.
 
Plenty of conical stylus available,actually im not looking for a spare stylus o got 1/2 dozen of these carts for a nice price.
Have not seen a replacement stylus for sale that has a "metal strap" inside the stylus body like the one i have.See pict
So no one can identify the manufacture of this cart???

What are your opinions on the manufacturer?
I found this pic of a Adc 220 and it looks similar to the Osawa.
