Koetsu rebuild

    I've got a broken Koetsu, will a rebuild (by Goldring) still have Koetsu traits or just sound like a re-tipped 103?

    The alternative cashing it in and buying something different?

    Which model, Mark?

    Rosewood Sig, its not Mickey's :D, on a deck I picked up at the weekend.

    That’s the model I have. I don’t have experience but did some online research in case. The overwhelming feeling is that once it’s been rebuilt elsewhere, it’s ‘no longer a Koetsu’. But surely that holds true for all makes. That said, if you punt over £5k on one of the stone jobs or similar then sending it back to Koetsu for a rebuild is probably not an issue (other than the wait).
    My reading was that the North West(?) rebuilder gets them sounding as like the original, which is probably important if you like that sound.

    The FG2 is certainly a quite different profile than the one Koetsu fit.

    I don't want to get into why, but its Goldring or no-one for me...

    I've never heard a strait Koetsu, however Mickey's was the best cart I've heard at home, but I believe its been worked on?

    I e-mailed Goldring at the time,they told me they couldn't do it,hence sending mine to NWA.

    If it's a Koetsu and your choice is Goldring or no-one then I'd say no-one and sell it as spares/repair for someone else. If you don't intend on ever selling it then Goldring may be an option but Koetsus really need to be rebuilt by them in order for it to hold its value.

    Koetsu preferably or NWA as a second choice for me on a Rosewood Sig. Worth it though as these are lovely carts with loads of character.

    If I were in your position I would also go Goldring (who I know do get a lot of Koetsu carts). You can also discuss with them how radical, or close to original, you want to go. When Andrew (Flatpopely) had his Asaka rebuilt by them he chose to keep it close to standard but I purposefully chose a different path when they did my black Troika.

    I assume that was because they were too busy at the time, generally though, they will let you know when they are able to accept new work. There are some carts they can't do but AFAIK, the Koetsu isn't one of them

    I have no idea of history apart from original receipt, £464 in 1984, and no cantilever so it'll be whole service/rebuild.

    'Replace the cantilever and diamond with a new Ruby GS fine line' has been suggested where that sits with original I have no idea?
    My original point was if I had that same cantilever and tip fitted to a 103, would they sound the same, or is there something in the Koetsu (wood body?) that makes them sound nice?

    I had a 103R in a modded body and a Koetsu Rosewood Sig at the same time and compared to an Esco modded 103 (Ruby/Paratrace) and I can tell you that modded 103's are not Koetsu's on the cheap. Not by a long way.

    I had a Koetsu Urushi done by Van den Hul. Cost £500 and got a really nice cart out of it and it does the business. You can call it Koetsu or Mickey Mouse, end of the day it sounds great and hopefully will last a long time.

    Dom at NWA tried to hard sell me, £1,500+, for £2,300 I could send it back to Koetsu and it would have come back as new, certified.

    £1500.00 is, by far, the most expensive re-tip service in the UK. When I had my Black Troika rebuilt by Goldring it was £400 (may have been £450) and included a rewind of the coils (silver was an option), a ruby cantilever and the top Gyger stylus!

    By all accounts going back to Japan will cost over £2k, too much for me.

    Changing tack, what’s a knackered Red Sig worth ?

    I’m not sure what you mean here Mark. Certainly the cantilever material and stylus profile are important but so are many other aspects of design when it comes to voicing a cartridge. For example;

    1/ The wire used for the coils
    2/ The number of turns in the coils (see above and diameter of said wire)
    3/ The material the coil armature is made from
    4/ The shape of the coil armature
    5/ The exact damper material used
    6/ The tension of the tie wire
    7/ the shape of the magnets/magnet field
    8/ The strength of the magnets
    9/ The shape and position of the pole piece
    Etc. Etc.....

    As an example, I’ve owned a number of Troikas and currently have two. One has the original aluminium cantilever and a Paratrace stylus (Expert Stylus Company) and the other has a ruby cantilever and Gyger S stylus. The Gyger equipped model sounds more open and with greater leading edge attack - but the basic bones of the sound is the same between the two.

    On the question of "what is a red signature worth" - depends on what's wrong with it I'd say. If its working and plays well but has high hours and doesn't track - maybe £300 to £400.
    But properly broken, no cantilever etc, I think its probably worth very little. Maybe Koetsu offer a trade up scheme that would make it worth more?
    Signatures and the standard Red are different sizes btw, so even if the receipt doesn't say, you should be able to prove what it is. Length Standard Red T: 2.2cm. Red K Signature: 2.4cm. Theres a market for the box and stylus guard if you have them BTW.
