Guitar Amplifier HEAD Piggy Back Mounting onto the V212T Speaker Cabinet: The V30H amp head is designed to “piggy back” mount onto Crate’s V212T enclosure. The V30H has slide-out mounting hardware which lock onto the posts on the top of the V212T. Loosen the knobs on the posts, slide the amp in place and lock down the knobs. The piggy-backed amp can be rolled around on its casters by the amp head’s handle, but do not try to pick the combo up by the amp head or its handle 6

Guitar Amplifier HEAD 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 evac- uated 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 vac- uum tube was a fact of life. The door to electronic amplification was now ope

Guitar Amplifier HEAD Important Information About Tubes and Tube Products (continued): "looser" low-end response and produces more harmonics at mid and high frequencies ("creamier" sound). These differences become more noticeable at higher volumes. The EL84 and 6L6 tubes produce a big low-end thump and have a very good dynamic range. They offer a more traditional "American Rock" sound. The EL84 and 6V6 tubes produce a creamy sound with nice dis- tortion. On the other hand, the KT88 produces a bi

Guitar Amplifier HEAD Important Information About Tubes and Tube Products (continued): You can check your preamplifier tubes for microphonics by turning the amplifier on, turning up the gain and tapping lightly on each tube with the end of a pencil or a chop stick (my favorite). You will be able to hear the tapping through your speakers, which is normal. It is not normal for a tube to ring like a bell after it’s tapped. If it does ring then it’s microphonic and should be replaced. Remember to us

Guitar Amplifier HEAD Important Information About Tubes and Tube Products (continued): 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
