Red House Tube Amplifiers is an Indianapolis-based shop specializing in tube amplifier repair and restoration. Their primary focus is vintage Marshall and Fender amplifiers, making them a solid destination for players chasing that classic tone from iconic gear. Beyond vintage work, they service and repair most tube amplifiers across brands, so players dealing with a finicky combo or a head that has stopped firing properly have a reliable option to turn to. Red House also offers general maintenance for solid state amps, though they keep their focus tight and do not handle car audio, home theater, or speaker repair. The shop operates by appointment only for drop-off and pickup, which keeps the workflow personal and allows for a direct conversation about each repair job before work begins. Players dealing with a failing power section, microphonic tubes, or any number of tube amp gremlins can reach out by call or text to talk through their specific situation before bringing gear in.
