My DT25 stopped working about 3 years ago. I have taken to 2 different Amp repair specialists and they have both said they simply can't get the transformers. There is no supplier anywhere in the world and Line 6 will not help. I myself have done extensive searches globally to no avail. Its an unacceptable disgrace to leave your customers who purchased products in good faith with Zero options just because you want them to buy something else from you, known as aggressive marketing, but allow retail outlets to still sell the product. So my DT25 has been sitting there gathering dust. I have a DT50 which is now having problems, cant wait for them to screw me on that as well.
