Professional component-level repair, structural refurbishment and preventative maintenance for valve and solid state guitar amplifiers, bass rigs, stage keyboards, synths, and active live PA sound systems across the North West. I take a personal interest and approach to my work in order to keep your performance backline and stage gear reliable and operating at peak performance.
Live equipment undergoes constant mechanical vibration, thermal stress, and accidental damage during transit or performances. I troubleshoot faults down to the individual component level, whether that involves tracing circuit breaks caused by liquid spills on a Nord keyboard, replacing damaged traces, or tracking down elusive grounding hums on a bass amp. I also source genuine replacement components, such as audio-taper pots to correct sensitive volume controls on Fender amplifiers, and can fabricate custom shims to physically reinforce fragile parts against future board flex.

Active PA Monitors and Stage Hardware
Modern active PA speakers often house high-power Class D amplifier modules inside small, relatively sealed cabinets. This makes them vulnerable to heating and thermal shutdown under heavy loads. When these modules fail or cut out prematurely, I investigate the thermal issues – investigating insufficient cooling, re-aligning loose inductor cores, and modifying temperature sensor thresholds. Where necessary, I can integrate custom quiet internal active cooling to manage heat dissipation effectively. As well as repairing hard faults like shorted amplifier chips, I also service specialised stage gear, such as Porter & Davies tactile monitoring systems.
