For what it is worth, I had a ULD-12 without the amp about 3 years ago and I call them about getting a new one....After about a week of figuring they desided they could build me a new amp with spare parts for 150.00.....I can't say enought nice things about them.....I have two ULD-15 now and have not had any problems.....I guess everything will wear out someday...But my ULD-15's keep playing....Good Luck with your repairs
