Help Identifying Koetsu Onyx
Wow, things are looking up again! Koetsu history is just so damn shrouded in mystery. And just when you think you've seen them all...Forgive me for my uninformed prior post. And thanks for posting your findings. That would be really cool if it is indeed a limited-edition Onyx Platinum. Such a gorgeous Onyx grain on your example, too. |
Thanks for the comments. There are 2 issues here. The first is whether the cartridge is authentic and the second is assuming that it is, whether it has platinum magnets. I bought this off a reputable second hand dealer in Japan. These things go fast in the Japanese used market so I pulled the trigger quickly. I've always wanted to own a Koetsu stone body but the retail price for a brand new cartridge is too prohibitive. Frankly, I didn't notice the missing cantilever cowl and the tapered front until the transaction was done, at which time I started doing some searching on the web but couldn't find anything useful. I did manage to find some other similar looking examples on the used market: https://www.vinylengine.com/turntable_forum/viewtopic.php?f=19&t=98006 https://page.auctions.yahoo.co.jp/jp/auction/282949853 I also found a Korean blog about a similar looking cartridge: http://blog.naver.com/PostView.nhn?blogId=imjbler&logNo=150081760337 http://cy.cyworld.com/home/28868771/post/3504472 I realize that there would probably be no absolute certainty on the provenance of the cartridge unless I send it back to Koetsu for a rebuild. I haven't had the chance to mount the cart so I will see how it goes. Also, I found this article talking about the history of Koetsu cartridges. Appears to be translated text but I couldn't find any information on the source: http://fs5.directupload.net/images/160608/24ta43zq.pdf |
I agree with most of the comments here. The shape of this is similar to the current Black and Rosewood Standard. Having seen a few Onyx Platinums before, I have never seen one like this. Nor have much older non Platinum Onyx looked like this. I believe Koetsu have/had fairly recently a non Platinum Onyx available again, but I've never laid my eyes on one. I am thinking there are 2 possibilities then: 1. It is a non Platinum Onyx (or Onyx "standard") of late production, which I can't verify as I've never seen one. 2. It is not genuine. Either way, sorry to say I don't believe it is an Onyx Platinum. |
Never seen any stone body look remotely like that. I have both an old non-Platinum Onyx Signature, a low serial-number Onyx Platinum, Coralstone Platinum, and Jade Platinum, lol. Platinum serial numbers start with a "P". Older Koetsu builds don’t have threaded mounting holes, and older still will use gold pins instead of silver. Older still, and you get silver top plates (like my Onyx Signature). And long-bodies go even further back than all of those. The top plate, mounting holes, and pins are not changed out by Koetsu on a rebuild (I know because I asked for it and they wouldn’t change it). I think (but cannot verify) that any genuine stone body with threaded holes and silver pins would be recent enough that it would have to be a Platinum model (all stones became Platinum at some point), and should have a "P" serial number on the top plate. Your pictured example violates this, and furthermore it features the simplified gold cover/guard plate without a raised "lip" -- which is a feature exclusive to the modern entry-level Black and Red (Rosewood Standard) models. So I think it has to be considered a strong possibility that someone shoved the guts from a modern Koetsu Black/Red into an Onyx shell (which itself may or may not have been genuine Koetsu). Either way, sadly there is about zero chance that this example actually has Platinum magnets. It might still sound very good, if the guts were genuine Koetsu and have not been unduly worn or tampered with. But if you were sold a Platinum, I think you did not get that :( |
Hi gobenchannt I have owned 2 stone Koetsus. Pls refer to the links, for the pics Jade - https://1drv.ms/i/s!AszPQc3v0wx9gt4KWjXJUvMhzMywmg Blue Lace - https://1drv.ms/i/s!AszPQc3v0wx9gaM9n-kVVRblIuYj6A I got both Koetsus from Melvin Ang - so they are 100% genuine From your Onyx pic - the slope from the front of the cart. seems consistent with both my carts. What is missing is the "bulge" of the gold metal plate, where the cantilever ends. I was made aware that in the past, there was an Onyx which is NOT Platinum (without this generator), so NOT sure where the "bulge" in your cart went to. Secondly, this could be a rebuild (by non-Koetsu builders) whereby there maybe NO bulge - but I have no experience on this Silver pins are standard fare in Koetsu carts. Still best to check with Melvin Ang FWIW - cheers ... Peter |
To advanced101: Please see https://ibb.co/dJZCyG To dover: I thought it looked really odd too. Its not a longbody and it shares the same shape as the black goldline and the standard rosewood, as you've correctly pointed out. I was thinking of sending it to Melvin Ang for a rebuild. I described the cart to him but he didn't have a firm opinion one way or the other. Hopefully someone who has seen this before or who used to own one can chime in. |
This looks odd, could be fake. The original Onyx’ from the 80’s had longer bodies & flat bottom. Never seen a slant front bottom on an Onyx before - I have only only seen this shape on Koetsu Black Goldline & Std Koetsu Red/Rosewood. The Rosewood Signature has a flat bottom. Try Melvin Ang at Koetsu South East Asia - he is very good on Koetsu support. |
