#Vintage stereotube amp kit how to#
An old trick is to keep your left hand in your back pocket all the time, so if you do get shocked, it hopefully won't reach your heart.Īlso, you'll need to know how to read a schematic, solder, and use a hand drill. When testing the amp out for the first time, use something like a twelve volt power brick instead of plugging directly into the wall, just to be safe, as well as to prevent things from exploding or melting. Discharge all capacitors through a resistor connected to ground, preferably with a voltmeter across it to be absolutely sure the cap has completely discharged. Some of the capacitors in this amp will hold onto a charge for a long while after the power has been switched off. If you decide to work on it with the power on, be careful. It involves high voltages and a lot of current that can make you feel decidedly unpleasant or even decidedly dead. This project is dangerous in a very serious way. Except, of course, for these next few sentences. Keep in mind that I am just a dude on the internet - take everything I say with a grain of salt. Going through the process of purchasing parts, planning, and executing is a useful experience for any maker. You can learn a lot about electricity and electronics from a project such as this. That being said, they look damn cool, and some people seem to think they sound pretty nice, too. Tube amps, unfortunately, aren't the most practical things in the world they consume a great deal of power, get very hot, and are big. However, tubes can also be used to amplify a stereo signal from another audio source such as a CD or MP3 player. You usually hear about tubes being used in guitar amplifiers, because they distort in a way that suits guitar playing. Vacuum tubes are old electronic components that act like transistors, controlling a lot of current with a little current. Ever wanted to build a highly dangerous, inefficient, yet awesomely retro piece of electronics? Well, I have.
