More recent ones have the double slots for convenience of adjusting tremolo spring tension. Some players like the solid one used on earlier JTV's, so every now and then, one comes across my bench. I forget what the transition date was from solid to double slot, but early 2012 sounds close enough. BTW,... 1202 is 2012, but not February 2012.

Factory strings are D'Addario XL110's, [10 to 46] sets are standard on all JTV as well as the new Variax Standard model.

A loose chassis ground inside the unit somewhere. Maybe an instrument-to-transmitter cable is failing. Log a ticket with Line 6 support and get it serviced.

And the drain rate is different. Whatever internal diode is in the Sony, will get blown. I used to see this incompatibility problem between batteries with Sony Discman's and Sony laptops. Using third party batteries is a dangerous coin toss for your gear. Normally I'd agree cruisinon2, but here, it's more about the drain rate and yes, the third pin too,... like the 3rd rail on The Underground. Companies want you to use their power sources because they are tailored to and somewhat assured to work with their product. Using a 3rd party power source, you never know what you get or how compatible it. Always a safe bet to go with what's specified. And so as a result there is an electrical reason for the 3rd pin. And those different drain rates do make a difference.

There's a diagram on pages 9, 10, 11, in the manual (hard copy or online) on how to hook up multiple units.

Daisy chaining the antennae is fine, see the manual on how to do that. Also bear in mind the dummy loads and how they are used.

Do you have a diagram of what you are trying to do, attach as a jpeg? There should be something about hook ups on the Knowledge Base, and in the manual. Are you trying to daisy-chain the transmitters, receivers or antennae?

Make sure the tubes get properly biased.

I'll save you the PIA,... nothing obvious.

"Gee, I hope all the transplants were done by one of the only 4 or 5 qualified people in the western hemisphere... ;) "---- You remembered. :) Well, at least the four or five that I trust to anyway (outside of some Tyler and Line 6 guitar people). I'm sure there are more out there, I just don't know who they are yet.

It needs to be re-tubed with the specified factory tubes, no substitutes. Go to a Line 6 authorized service tech for this. With Bogner designed tube amps, the way the gain stages are set-up, these amps are unforgiving when it comes to any modifications. Then they must be biased to specifications. Best to go to a Line 6 authorized servicing, as they will have access to our service data and information. These are valve amps with high voltages, shock hazard is not to be taken lightly. It should be serviced by someone who thoroughly knows this product's circuitry.

Nickel/Silver alloy on all the JTV Models.

If the tube is wearing, the cathode-to-heater current may leak too much and that may sag a supply line. The relay would not fully energize, it could dither.

The receptacle fuse,.... that side of the transformer. Not related to the fuse in the bulletin. I have a little bit of history with Yes, back in the late 70's when I crewed for Iron Butterfly. The two bands were long time pals. Interesting times.

I made sure Mr Howe's amp had all it was suppose to have. But his issue was different. Typically, in general, as I mentioned in a prior post here, tube ought to be changes out 12-18 months for gigging musicians and 20-24 months for weekend warriors. You look like somewhere in between. I knew a guy with a Phase Linear tube amp, got by without a tube change for 15-years. Changed the tubes, blew in two weeks, change the tubes again and went on for the next 5-years (at which point I lost track of him, so I don't know how much longer they went). Tubes ar always the variable in these things. Xformer going before the fuse,.... odd, your serial number should be able to do that,... which fuse went?

The fuse thing was solved some time ago, as was the transformer thing. They were separate issues that got resolved some time ago. There are several ways to pull down a transformer in a tube amp. Not sure what occurred with yours that got it to fail.

How often do you gig? How long has it been since you changed out the tubes? What tubes were in them?

It will need to serviced. You've gone as far you can. You've logged a ticket, someone from support will respond.

It can be three things,... -The power tubes (valves)haven't been replaced and re-biased in 18-20 months. If they are getting old and failing, then they may be pulling down other circuits. -Or if the tubes (valves) are not the specified tubes (valves) for the product, the bias and heater voltages might not be correct for other tubes. -Could be the foot-switch circuit in the back of the amp. Both would have to be looked at by a Line 6 authorized service with access to service info and Line 6 technicians for that and other products. Tube (valve) amps have high voltage lines which are shock hazards in them, and should be serviced by an authorized technician who knows that product.

Check the Knowledge Base on Flash updating. There should be a recently updated document.

Since you think I'm not trustworthy or of use regarding this post, I am handing the baton over to others, and they will continue on with this, and I will no longer be following or responding to this topic and post. It's been interesting. Bye.

Upper harmonics when scraping against wound strings. And if you're using an overly resonant Model patch or amplify enough, it will exaggerate the effect. I do that all the time on my non-JTV guitars too, when I do a Van Halen, Deep Purple, Pink Floyd or a Ronnie James Dio piece. I can do that with a finger, finger nail or a flat pick.

Sorry to disappoint your distrust, we have been looking at the video and going over this stuff.

re: Clay's query,... it's not preamp, and I can't get into the why I know, because that's circuit level stuff that I can't get into. If I didn't know better, I'd think the same. Good idea though. re: Miroslav's request to answer yellowdog,... wouldn't know where to start, multiple items and all. Have to go thru those one at a time. A somewhat varied post by him. Interesting, thanks for bringing that one to my attention. re: this post in general,.... it's been being looked at for some time by a number of us. Piezo swapping,... the bridge and it's piezos were replaced. Main board swapping,... that was replaced. Firmware,... if that was the problem, then we'd all have the problem, and we don't. Preamps,.... like the firmware, if it were that, then we'd all have the problem, and we don't. Something else is involved here, that is exacerbating whatever the problem is. It is being looked into for a while now.
