Thanks Adam but Im pretty sure its not only the tubes as my power light will not even come on.

Yea Drop I here ya. I hope it gets sorted out because the amp does sound good, when it works.

Still waiting on a ticket reply to see if I need to ship, or take to my local Line 6 auth techie...

I dont know what the range of serial numbers are invloved, but here is the email contents...

(Another thing FWIW- I didnt get the email for my DT-25, and its the one that died... go figure.....)

..... From Line 6.....

You are receiving this email based on your DT50 serial number’s manufacture date. Line 6 has found that your amp qualifies for a hardware upgrade that will prevent the possible failure of its power supply. This upgrade will be performed free of charge under Technical Bulletin 059 and can be performed in one of two ways:

Contact your local Line 6 Authorized Service Center and request that Technical Bulletin 059 be performed. It may be best to contact one or more service centers ahead of time to understand when you can expect the amp to be repaired. For a listing of Authorized Service Centers in your area, please go to http://line6.com/service_centers/.
Contact Line 6 directly and ship the amp to us. Package the unit in a box with adequate packing material to insulate it from possible freight damage (Line 6 is not responsible for freight damage due to insufficient packaging.) We suggest you use a method of shipping that offers a tracking number. We will make the repair and ship the amp back to you, so please make sure that your Line 6 account’s shipping address is updated. The repair can be set up in one of two ways:
- Open an RMA (Return Material Authorization) service request ticket via your Line 6 user account (this method expedites the process). To do this, log in to your Line 6 Account. Click this link: http://line6.com/support/tickets/add.html. Type “repair” in the search box, then click “Open Ticket." Select your amp and then request an RMA to have TB059 performed. You will receive an RMA number and shipping instructions via the ticket.
- If you prefer to call us: dial 818-575-3600, press 3 for Technical Support and Customer Service, press 3 for the Service Department, then press 2 for Repairs (RMA request).

We want to make sure that your DT50 will perform well for years to come, so we feel this action is necessary. We apologize for any inconvenience this issue may cause you.

Best Regards,

Line 6 Customer Service

End

And yet Silver, you are the first one to scream like a little girl for a person with an attenuator when you need one...

Added: No Silver, Im not a member of the NRA (all though anything that supports and protects my amp and the Constitution is worthy of membership)....! Dont believe me ask Uncle Ted...

Re: DT-50, HD Pro and L 6 Link not working after DT25 died and Tech Bulletin 59 done?

support@line6.com — Sat, 20 Apr 2013 21:02:31 GMT

Update: Things just didnt add up so I took a look myself...

The Line 6 Service Tech left off the ribbon connection from the "A25 Speaker-L6-Link-foot board" to the "A25 main board" inside the amp head....

I know this because all was working before I took it in, and its a very short ribbon cable, couldnt have come off without help. Go figure....

Thats the signal path ribbon cable for the Line 6 Link connection to work... I found it dangling inside the chassis...

Once the connector was put back on its port and the amp re-assembled, all is fine now with L6-Link and the DT50 and Pod HD.

Altho I still need the RMA ticket for the DT25, as its dead as a hammer...., Its nice to have some things working again.

DT-25 Died today

I turned it on after making a up L6 Link connection , it made a horrible sound for a half second, and then went dark.

RMA ticket turned in to Line 6 support for repair. I had no issues with it since it was bought new last October, until now....

DT-50, HD Pro and L 6 Link not working after DT25 died and Tech Bulletin 59 done?

support@line6.com — Sat, 20 Apr 2013 18:40:47 GMT

I just had My DT-50 updated by a Line 6 listed qualified service tech last week, and it plays with the Guitar alone just fine, however when I tried to use Line 6 link to hook it up between the amp heads and the Pod HD pro, the DT-25 amp died as soon as it was switched on, and the DT-50 wont make a sound now either using the VDI Variax input or the standard 1/4" jack thru the HD-Pro with L6 Link.. Coincidence? I cant see how doing the upgrade fuse change (tech Bul 059) would cause another amp to die completly and cause the L6 Link not to work too... Too many variables involved, but they are not working now... Loads used were 16 ohm Marshall cabinets for both amps with NO attenuators involved, fyi...

Im using the same XLR cables that worked before between the three units... There is only one way to hook L6-Link up between amps and the HD-Pro because of the gender connections.

I have filled out a ticket on the DT-25 as it is still under warranty, but I am wondering if the DT-50 and or the HD-Pro is damaged as well now....

I have RTFM and in the HD-Pro setup pg's 9 internally it does not show that the DT50 is indeed linking with the HD-Pro as the manual suggests...

I have re- flashed both the DT-50 and HD-Pro units since this happened.... No help. Pod HD Pro works fine on its own too...

Did the DT25 take out the HD-Pro's L6-Link comms as well as the DT-50's when it went south? Do I need to make another ticket, and if so, for which units???

Any suggestions on what to do next?

Zap, of course there was a reason some of us got the bulletin, and I do know why it was i got one. It was sent to me so that the internal fuse that was replaced (with another type fuse) would up open later than the changable fuse that we can get to on the back of the amp in an over current condition... Now, the serial numbers on the units may have flagged them as to who needed the fix, but the reason for the fix was that the fuse inside the chassis was wrong and needed the right one installed. I also know that this thread exists because of those who suffered from transformer failures. Hopefully there wont be more...

Space, yes mine is an early one as well that I just got back from the shop. I have run mine on a less than hard path volume wise and babied it. And I still took it in for the upgrade. I think that you should have the correct components installed even if you dont plan on pushing the limits. And that doesnt make it a defect, until of course your transformer blows up. I also think that the issue here for Line 6 was that it might fail without this upgrade done, and not that it was guaranteed to....But, it was a design change, however small. That took a pair, and cost them $$. And I am glad Line 6 owned up to fixing it for the user for free. Their stock went up a mark or two for me in doing that. Noted: Owning up and taking responsibilty for your actions and mistakes made, is a rare gift these days....

not really true, because they did fix them in production... the early ones left either missing or with the wrong fuse...
I don't think the general design is at fault... as much as perhaps the implementation of that design....

Actually, "mine" is getting fixed in "post" production Zap... After the fact of paying for and receiving the amp... Lots of others were not fixed in production either, and kinda explains the reason for this thread Im thinking... Hopefully the fuse is the issue, as time will tell. And that information came to me from my service tech about the fuse being wrong.... Not from Line 6....

Well Zap Im kinda mad at you for not telling me you knew all this stuff to begin with ...

Space glad you clarified yourself, and I do see what you meant by it now. Too bad Zap wouldnt tell me...

You wernt talking about the impedance load differences, only the maximum current flow and heat build up through it.

And your right after the carification, in running an amp flat out with or without an attenuator will normally reduce the life of the output tubes since maximum current is flowing and maxiumum heat is being generated during this condition. I personally wouldnt have EVER run my amp flat out all the way up using an attenuator, but some idio errr... people do... ; )

Which brings me to a what if question, if you will... Had Line 6 design engineers (not knowing their design and QA testing stuff) used something like an attenuator to better load test these amplifiers in cranked up over time test, before mass producing them, would we have had the problems we are seeing here in the 1st place? And if they did, then why all the failures? Did they not go far enough, or did the parts people drop the ball? An explanation from Line 6 would be an awesome read, for those who have smoked a DT series amp....

Oh yea BTW- Zap. A light blub burns out quicker because its "designed" to do so. Had they placed in all US incandescent blubs a 130 volt filament, they would not sell near as many blubs as the current (pun intended) sales records show.... But, you already knew that

Good to see Line 6 supplying the parts to the service reps.

Using a good attenuator hooked up properly wont hurt the amp fyi. I know ..., the general consenses on this (stay away fron de voodoo)

Glad to know the info about the fuse is the same...
