VT-40.2 Integrated Tube Amplifier Front View Back View Maintenance and Cleaning To maintain the amplifier's appearance, it is recommended use of a dry or slightlydamp soft cloth to keep the exterior of the amplifier free from dust, lint or dirt. When cleaning the amplifier, make sure the amplifier is turned off. WARNING: DO NOT apply a damp cloth to the vacuum tubes when they are warm or hot. Damage to the vacuum tubes will result.
Vacuum Tubes Most of the maintenance on your amplifier will involve the vacuum tubes. The tubes used in the VT40.2 are type 6N3. The tubes have a lifespan up to approximately 5 years of outstanding performance depending on usage. Tube wear is gradual and usually goes unnoticed until new replacements are installed. Worn tubes tend to sound flat with reduced punch, clarity and high end.
