We repair all of the preamps and power amps made by Audible Illusions. By far the most common repairs are on the many excellent  preamps in the Modulus line. We repair, overhaul and upgrade these units, including volume control and power supply modifications. Usual problems are overheated resistors, noisy tube sockets and power supply / filter caps issues. We have some options available for the common noisy volume control problem, please inquire.

Please note: We receive many requests for AI parts and inquiries on items sent to AI for service. We are a independent service company and cannot supply parts or information on any unit sent to AI for repair. We have no contact info for AI
