Cut any extra holes required on the amp chassis, which is the metallic body of the amp and ensures that all the components -- the tubes, the bias rail, the fuses and the resistors -- have slots to fit in. The amp chassis comes with slots for most of the components and is marked to tell which component goes where. Bolt in firmly the components on the chassis before you connect any wires through the system. Bolts for most of the components come with the chassis, but you have to buy some for those components with holes you bored.
Wire the power supply and output tube, which are in bus form, by connecting the bus to the three slots from the power transformer -- which is the heavy assembly with a copper wire used to regulate the electricity through the system, at both the ends and center of the bus in a triple ring.
Connect the pre-amp to the amplifier. You may have to use two pre amps, one to supplement the other's gain. Plug in the entire system to a power source. Connect a sound input, such as a radio or a bass guitar, to the amplifier and 1,000-watt speakers to the output terminals, then power it on. Make sure you take all necessary precautions to prevent electrical accidents, since this project involves high voltages.
