Protect the amp from mechanical knocks (tubes!).
Let the amp cool down before you transport it (approx. 10 minutes).
Tubes need about 20 seconds to warm up after you switch the power on,
and furtheron a few minutes before they reach their full power capability.
Avoid storing the amp in damp or dusty rooms, they are hard on jacks,
switches and potentiometers.
Make sure air can circulate at the rear side and the top of the amp
to allow for adequate cooling (increases component life).
Never operate the amp without an adequate load.
Replace tubes with select replacement tubes (special selection criteria)
to avoid microfonic properties, undesireable noise and unbalanced performance.
