For 2 days I've been trying to figure out how to reply to posts made in existing threads and I can't figure it out so I will start a new thread with hopes someone can guide me in the proper direction. I apologize if this has been covered in detail elsewhere. After struggling trying to define some of the many problems I'm having with my DT50 2x12 rig I stumbled onto the issue of the blown power transformer. I am currently trying to get my gear "road-ready" and have yet to be bitten by the blown transformer. I never received an email regarding Technical Bulletin 059. That being said I got a support ticket and sent in the following request. "RE: Technical Bulletin 059 I don't think I received an email regarding the blown transformer issue and currently my amp appears to be working fine but I plan on taking this amp on the road for a couple months so I thought I'd send in my serial in hopes you might be able to tell me if my amp might be one of those affected by this issue. Here is my serial. Thanks! (21) A891S6040XXXXX." I received a prompt response from Line 6 support which said the following. "Hello, Yes, I have reviewed tech bulletin 59 and I can confirm for you that your amp is one of the amps that could possibly be affected. I'm not sure if your amp has already been serviced regarding this issue, but this would be a warranty repair. Since you are in Canada, you would have to take this unit to an authorized service center in Canada. Authorized service centers can be searched at the web address below: http://line6.com/service_centers/ I hope this is helpful." So my questions are as follows... 1. For those of you who have had your amps serviced under this warranty "recall" have you continued to blow transformers after the service has been rendered? 2. One of the Service Center locations listed is fortunately the repair shop I use regularly on my gear and I have always been very satisfied with its work (Backline Audio, Vancouver). How does the warranty work? Do I just bring it into Backline, tell them it is under warranty and let them deal with it? 3. Other than the potential reliability issue I love this amp and the way it interfaces with my HD 500. Can I rely on the fact that servicing the amp in the manner indicated above will give me the reliability I require being a professional musician or would I be better off selling the Line 6 gear and buying a more reliable product. Any info would be valued, thanks.
