Please contact us before sending your amplifier in.
Our address is The Amp Doctor Ltd R/O 79 Leighton Ave Leigh on Sea Essex SS9 1PZ England.
Please note we now only work on Genesis, Phoenix Gold, Pre 2000 SoundStream & Rockford, JL (Slash & XD only) and a handful of Orion / Kicker models. We no longer get involved with any other brands due to the time taken to get circuit and service information and / or parts.
