We offer a 15 year warranty on construction. This includes the cabinet, chassis, hardware, speaker mounts and wiring integrity. I cannot guarantee components that I purchase from other OEM's-these include: speakers, transformers, potentiometers, switches and jacks. Electronic components are likewise out of my control as far as a guarantee however, if an electronic component is damaged due to a problem with the circuit integrity, I will absorb the cost of replacement.
All dAAb amps are turned on for three five-hour stretches before shipping. Electronic devices, if they are going to fail, usually fail during the first few hours of use. This procedure greatly reduces the risk that one of our amps will fail in your hands. During the "on" time each amp is played to test for tonal integrity and general functionality.
Any unauthorized modifications or attempts at repairs by unauthorized persons voids all warranties or obligations from dAAb amps.
