responsible for damage caused in return shipping. Science Amplification will pay for the
shipping back to the customer after the warranty work is completed.
In general, we will be able to fix your amp for free, and help with tube changes, etc. if needed.
We will also be happy to modify the amp in any way possible until the amp is perfect for you.
Non-warranty repair is also available – please inquire for shop rates.
Care and Maintenance
Do not use household cleaning products. If control panels need cleaning, use only a soft clean
dry or damp cloth to wipe off smudges. To clean tolex, wipe with a damp cloth.
Periodically check the 4 mounting screws on the bottom to make sure they are tightened.
These screws secure the chassis to the head cabinet, and also insure contact to the aluminum
RF shielding plate inside the cabinet.
If possible, move the amplifier when the tubes have had the chance to cool down for a couple
minutes. Because the tubes get very hot, the elements inside become more vulnerable to
physical damage until the tubes have cooled. In general, try to move the amp off stage last.
