Important Information About Tubes And Tube Products: A Brief History Of The Tube: In 1883, Edison discovered that electrons would flow from a suspended filament when enclosed in an evacu- ated lamp. Years later, in 1905, Fleming expanded on Edison's discovery and created the "Fleming Valve". Then, in 1907, Dr. Lee de Forest added a third component – the grid – to the "Fleming's Valve" and the vacuum tube was a fact of life. The door to electronic amplification was now open. During World War II,

The Nature Of Tubes: Why (And When) To Replace Them: Tubes are made up of a number of fragile mechanical components that are vacuum-sealed in a glass envelope or bubble. The tube's longevity is based on a number of factors which include how hard and often the ampli- fier is played, vibration from the speakers, road travel, repeated set up and tear down, etc. Any time you notice a change in your amplifier's performance, check the tubes first. If it's been a while since the tubes were replaced and

Survival Tips For Tube Amplifiers: To prolong tube life, observe these tips and recommendations: • Match the impedance of your speaker cabinet(s) to your amplifier. Improper impedance matching will con- tribute to early tube degradation and may cause premature tube failure. • Make sure the speaker(s) are properly connected prior to turning on the amplifier. • After playing the amplifier, allow sufficient time for it to properly cool down prior to moving it. A properly cooled amplifier prolongs t
