    Not a lost cause just yet.

    1) Do not use JJ, Mesa or Groove Tube. They may be fine tubes, but not in this particular amp. I've had nothing but trouble with those tubes, in this amp. This design is not forgiving when it comes to tubes other than what is specified for the amp. Use the specified Electro-Harmonix EL34. 2) Don't mess with internal fuses. 3) The fuse eluded to in the previous post is a very specific fuse, and should be changed out by a factory authorized service center that knows the product. You can't use just any fuse for that particular one. 4) This is not a panel fuse for users to be dealing with because a) of the shock hazard, and b) because using the wrong fuse will damage the circuits. 5) If you changed the fuse out with the exact number you had in there, it may not have been the correct one. 6) Be certain your amp is registered and then log a support ticket in your account. 7) Shock hazard, stay out of the inside of the amp. I've serviced hundreds of tube (valve) amps (including the Line 6 ones). 8) I know which capacitor failed, putting another of the same fuse won't help.

    Don't know what this Yamaha Dreamscape system is. Can't find it on the web, or the Yamaha site. rimrocked,... are you referring to the,... http://www.dreamscaperecording.net/equipment/ ... system? If so, this is not a Line 6 product or product line. You must be thinking of the Line 6 Stagesource and Stagescape, those have mixers and speakers, and are not Yamaha products. Not all of the components in this "Dreamscape" are Yamaha. Apparently some confusion as to what's what here. This "Dreamscape system" is not a Line 6 product line, or I'd be one of the techs servicing it. Don't know why he would blame Line 6 for a product line that isn't even a Line 6 product line.

    The JTV-59. Sometimes it takes more than one pass for the update to lock-in.
  5. psarkissian
    The mod cable being used here in the video is for doing program updates through Line 6 Monkey and Workbench HD. The correct cable to use for playing through is the VDI cable with the XLR shells on both ends for a proper lock. Have you do a Flash update? Sometimes when it lights up, but does nothing, it is because of a failed Flash update. Do a re-Flash of the latest version and see if that clears it up.

    If your problem is with those two components mentioned, then replacing them will not solve your problem, other items will be affected. It should be troubleshooted by a Line6 or Line 6 authorized technician. Otherwise you're left with getting a coffin assembly. And the A/B box should be checked out as well, just to be certain that it's still functioning.

    Not that I've found. Some normalization was done to recent firmware updates, but you can only normalize so much before it has a bad effect on the model patch.

    Needs to be serviced at an authorized service center that knows the insides.
  9. psarkissian
    It could be a number of things. Make sure the guitar is registered, then log a support ticket in your account.
  10. psarkissian
    We make a G10 Wireless.

    Variax Standard and JTV use the same piezos, just mounted in different saddles.
  12. psarkissian
    There would be some notes or labels on the packaging. Both 50-Ohm mic cables and 110-Ohm XLR cables adhere to AES/EBU, ANSI, ISO and ITU standards. And the better brand cable makers also have markings on the cable regarding that. If you don't know what you're getting, hold off until you do, or find one that is correctly marked and labelled.
  13. psarkissian
    I don't see it registered under your user name. Do you have more than one account? The reason for contacting customer support is that they are the ones who would issue a replacement if they okay it. A guitar VDI/USB is a simple thing.
  14. psarkissian
    As to question #1,... no. They are okay for the older version Variax. But JTV's,... the earliest that would work would be an X3 Live. And that was with the earlier JTV firmware only. The later firmware is just with the VDI/USB interface. Make sure you JTV-59 is registered, then get in touch with Customer Support.

    It has to be 110-Ohm cable for Line 6 Link,... and not 50-Ohm. That is a must, and there are no substitutions, or there will be problems down the road. It has to do with impedance matching, those are the rules of physics. abaxe,... good question. And the only stupid question,... is the one that is not asked. There should be something about cables, usage and impedances in the Knowledge Base section of the Forum. For those who want to get deeper and better informed about cables, usage and impedances,... check out books by Steve Lampen of Belden Cables.
  16. psarkissian
    Two kinds of cable here,... - XLR 50-Ohm for mic cable use. - XLR 110-Ohm, AES/EBU, for other uses such as Line 6 Link. These uses are not interchangeable. It has to do with impedance matching between devices. Do not use 50-Ohm mic cable for use as Line 6 Link.
  17. psarkissian
    "Is the JTV 1/4" output a TRS of some kind?"--- Yes. More about that in the Knowledge base. TRS:: tip= signal, ring= +V, sleeve= return. It's like that with many guitars with active circuitry.
  18. psarkissian
    XLR is a balanced line, and the 3rd line ties to the shielf for chassis ground. 50-Ohm XLR is for mics, 110-Ohm XLR is for L6 Link. TRS guitar is for guitars with active electronics like a Variax or JTV. Because of impedance considerations and its affect on cable performance, many of the afore mention cables have length limits. So don't go beyond that.
  19. psarkissian
    FBV mkII does the USB to RJ45 interfacing. Monkey for firmware updates and Spider IV Edit for other things. Checkout,... http://line6.com/software/index.html ... for available downloads.
  20. psarkissian
    Correct.
  21. psarkissian
    There's a risk of damage to some components. Regulation circuit won't like that over time. They will get stressed over time. When you plug in the TRS, the battery is engaged. Together with the XPS,... not a good idea.
  22. psarkissian
    Take the battery out. TRS cable engaging the battery AND using the XPS power system would result in a voltage doubling that can damage something.
  23. psarkissian
    TRS:: Tip/Ring/Sleeve in an active circuit like this is typically use for signal, +Vdc and return (or some analog circuit common or ground). Over long lengths, there can be a sag in the DC rail and/or a resulting change in the impedance. Change in impedance can contribute to hum noise. DC regulation can do only so much. So yeah,... snhirsch has got it.
  24. psarkissian
    15ft TRS to the XPS is normal, keep it there. If you're going to go for a longer length, make from the XPS to the amp, and try to that length down to about 25ft. Don't go beyond 30ft.
