Tube amp service and repairs

For guitarists and audio enthusiasts alike, tube amplifiers hold a special place in the world of sound. Known for their warmth, dynamic response and harmonic richness, tube amps are prized tools for shaping tone. But like any piece of analog equipment - they require ongoing care, and that’s where regular maintenance and timely repairs come into play.

Tube amps are often described as “alive”, thanks to the way vacuum tubes respond to input. Tubes wear out over time. They can become microphonic, noisy, or simply fail. Ignoring these signs can lead to degraded tone, inconsistent performance, or even further damage to internal components.

A proper repair not only restores your tone, but can also reveal underlying issues like bad solder joints, leaky capacitors or worn resistors.

A dc amp services we go beyond just swapping tubes by testing voltages, trace signal paths and evaluating components to ensure your amp is operating within spec.
