Handling and Care Protect the poweramp from mechanical knocks (tubes!) Let the poweramp cool down before you transport it (app.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 poweramp in damp or dusty rooms, they are hard on jacks, switches and potentiometers.
