Dennis of Audio 3000 is the man you want for all your amplifier repair problems. After taking my amp to a (supposedly) reliable repair guy a while back, I found my amp in dire straights yet again. Dennis not only fixed the problem, but made sure to correct all the other mistakes that were done by the aforementioned repair man. He was meticulous in his work and made sure I knew exactly everything that had been done. He goes above and beyond, which is the sign of an expert professional.
