Yamaha 01v Fader Repair?
I'm fairly handy with a soldering iron, but I'm betting this one's
beyond me. Picked up a used Yamha 01V mixing console for $350. Channel 11 has issues. It will not allow any signal to pass until it hits about 80% of the fader (as you fade to the top of the fader), then it comes in full force. It also won't move (motorized) through the section where it won't register. When in the 20% of the fader that works, it's flawless... but... I'd rather have all 12 faders working perfectly. Any ideas what could cause this? Any thoughts on a fix? I have some Caig Deoxit, which I was going to try tonight, but I'm fairly certain it's not just a dirty fader... although I could be wrong, I suppose. There is a local repair center that thinks they can replace it for around $150. Seems a bit steep for a simple fader replacement, especially if I could do it myself, but, that motorized portion makes me think this could potentially be beyond my skill set/knowledge base. Thanks, folks! Any input is greatly appreciated! Corey |

If that does not work just replace the fader. sebastian -- "Kaffee? Du sagst Kaffee dazu?

Depending on what kind it is, you might be able to patch the element with conductive epoxy. I wouldn't trust that as a long-term repair, though. There is a local repair center that thinks they can replace it for around $150. Seems a bit steep for a simple fader replacement, especially if I could do it myself, but, that motorized portion makes me think this could potentially be beyond my skill set/knowledge base. Wait until you find out what parts cost. $150 is fair for something that is going to require extensive disassembly and a fairly expensive part. You could do it yourself and it probably won't even require soldering, but you won't save all that much I bet. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

You got a 01v for $350 what the heck are you worried about ? Send it somewhere for repair, or settle for the 14 faders that work. Sigurd |

I have some Caig Deoxit, which I was going to try tonight I'd keep that stuff away from it. How good of a repair technician are you? Can you replace it with a fader from another channel without someone writing the service manual for you that Yamaha probably never published? I'd do that. If it works, then your only problem will be to find a replacement fader. There is a local repair center that thinks they can replace it for around $150. Seems a bit steep for a simple fader replacement, especially if I could do it myself Take it there. If you don't have that fader out by now, I'll bet you can't do it yourself. And if it isn't the fader, maybe they'll find out what it is and fix that. -- If you e-mail me and it bounces, use your secret decoder ring and reach me he double-m-eleven-double-zero at yahoo -- I'm really Mike Rivers ) |

Thanks for the info, Scott! I haven't looked into the part yet. In my experience, getting parts out of Yamaha is painful, time consuming and often fruitless, unless you're an authorized repair center. It sure doesn't LOOK like it'd be hard to get into, but... I'll probably take a shot at it tonight. We'll see what's in there! Corey |

Remove all the screws from the side where the rack rails sit as well as all of the screws holding the top part in place. IIRC that's 4 screws on the back and 4 in the front right below the armrest. Once these are removed, you can flip the top part over to the fader side of the mixer by lifting the back end up. Be careful, there's a ribbon cable in it that could be a little short...

Have a look at these: http://members.chello.at/martin.heller/pultunten2.jpg (01V open) http://members.chello.at/martin.heller/platinenoben.jpg (Fader-Assy.) Contact Yamaha for spares, AFAIR a replacement fader for one of their smaller desks is about 5,- EUR (not motorized though). I didn't have to remove any faders when our 01V was flooded in june but I guess it's a standard ALPS-type anyway. sebastian -- F: Was ist ein Mathematiker?

Thanks for the post, Mike (and everyone else who posted thoughts/ opinions). I'll post and let everyone know what I find once I'm done. Corey IIRC, the fader has 2 tracks, one for the audio and one to measure the actual wiper position. As there is no audio over part of the audio track, that track must be assumed to be broken. If the 01V doesn't manage to move the motor at all during calibration, the feed to the motor or the motor is probably broken as well. Someone may have trodden on or dropped something on the fader, or it could be that the previous owner swapped a bad motor and a bad fader track into a single channel.. Regardless, it is not that difficult to swap an entire fader assembly between channels. That will tell you everything you need to know. Gareth. |

Now that I've actually taken the plunge, it makes sense to head back in. You were right, by the way. They had EXCELLENT suggestions and thoughts in regards to the bad fader. Looks like I can replace it myself for between $35-50, if it's not the motor. Once I'm done rewiring the headphone distribution in the studio I'll have a chance to dig into it. Corey |
