Amplifiers typically need a tune-up once a year, more often if you're a gigging musician. My tune-up jobs include:
Testing all tubes
Cleaning and lubricating potentiometers (knobs)
Inspecting all jacks
Testing high voltage filter capacitors.
Cleaning all tube sockets
Performing a general cleaning of all accumulated dust, dirt, and grime
Inspecting of all components for loose connections or poor solder joints
Standard shop rate is: $70 per hour.
Most repairs are charged 1-3 hours of labor. Parts are not included.
If you bring in an amp and end up choosing to not have it repaired, there is a $40 minimum bench fee. This is common practice.
From barn finds to road worn amps, I can bring your amp back to health and keep it running for another 50 years.
Electrolytic capacitors have a lifespan of 15 years. In order for your amp to remain reliable and safe, these should be checked for failure.
