It's really a shame because the DT-50 is truly a great sounding amp but the power transformer problem is going to kill millions of dollars of sales because people will discover the problem when they start researching the amp before they buy it. There are lots of posts online everywhere about it. Bogner's feet should be held to the fire on this one and they should offer to fix the problem or revise the amp design and reissue it. I hope Line 6 does not ignore this problem for the sake of profits. They could turn a negative thing into a positive thing by taking care of their customers (which it appears that they are doing) which would foster more confidence in their products. My DT-50 has died 3 times in 14 months due to a bad transformer and I only played it for 30 mins twice a week.

I have seen several posts where the DT-25s are experiencing the same problems. Not sure if the circuit is causing the power transformers to blow or if it's just a poor designed component that they need to replace it with a better one. They need to do something though because consumers are reporting this problem all over the 'net and losing confidence in this product which is going to end up costing them a lot more in the end due to lost sales. It's one of the best sounding amps I've played but that doesn't matter because the reliability of the amps is a super deal breaker for most consumers.  I do know that the relays in the amp which give it different topologies causes power surges in the circuit and that the XLR output jack is tied to an output transformer (don't know if it's tied to the power transformer though; I'm just repeating what I've read several times in this regard) and it pops when you turn off the power; I always put my amp in standby when I turn it off and it still doesn't help. My amp is connected to the PA system through the XLR output jack at all times so I don't know if that has anything to do with it either but I doubt it. I hope they resolve this issue soon or it's going to cost 'em.

You would think I would have received one of them but then again I don't have to be made aware of this problem because I've been very well aware of it ....4 times now! Hopefully they've had a word with Bogner on this issue and resolved it... But that creeping fear in the ack of mind makes me wish I'd spent the money elsewhere...

I'm guessing you will be back in here to post when it happens to you. This is only but one of the many places that the power transformer problem has been reported online. Do a Google search and you'll see it's not a few isolated incidents. What's more important is how Line 6 is handling this situation - they are doing the right thing and notifying people that have potentially affected amps that they can send them in for repair. They have also offered to repair many that were out of warranty because they realized that it was the right thing to do given the price of the amp. This thread was simply set up to make them and others aware of this problem as I noticed it was becoming a common occurrence. It wasn't to slam them. They have done me right and I will continue to buy their products and recommend them to others.

About a week ago. I think they made the decision to replace the amp because the amp had to be serviced 3 times previously and the transformer being replaced each and every time and still blowing and the fact that their tech had obviously damaged the amp by what I think was problem the amp falling over on the edge of the workbook or onto a tool. I am an investigator by trade so I'm used to keeping meticulous records and am observant probably a little more than the average guy so I knew that there was no damage to the front face of my amp when I packed it up in the original shipping materials it came with (not that anyone else here wouldn't have noticed too) and shipped it and knew damage like that wouldn't have occurred in transit. By habit, I keep all my records organized and keep all documents just in case for later use. I basically wrote out a chronology of what had occurred and supporting evidence like technicians notes, date and times the  amp was repaired, shipped, received back fom repair, symptoms, photos, etc...basically laid everything out for them to how them I hadn't abused the amp, took good care of it, and hadn't even used it that much, didnt move it around, wasn't a gigging musician per se, etc...I also let them know I hoped they would consider replacing the amp as ll efforts thus far hadn't fixed the problem. I think the fact that their tech had damaged the mo might have factored into it too. I think they understood I was trying to be reasonable and not blow my cool either. I think a lot if people blow it on that one in these types of situations and that kills the deal for them with most business owners. I wholeheartedly appreciate what they did and I think they turned what could have been a negative thing into a positive thing. As a result, I will let others know that they stand behind their products and that they made a customer with a bad situation happy...:)
