【Definition】 A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal..
【Function】 Connect this preamplifier to the audio source with 6J1 tubes and effectively filter the digital flavor. Tube amplifiers produce a warmer or more natural valve sound, make music and the human voice is relatively good..
【Capacitor Filter / Coupling Capacitor】 Eight 470UF capacitor filters are very clean, excellent power supply does not cause humming, filaments are supplied with 12 V DC and must be connected in series to reduce noise. The coupling capacitor is a high frequency electrodeless electrolytic capacitor and low resistance..
【Features】 With the DC 5.5 * 2.1 socket and 12V AC transformer, you can also use a 12V AC transformer without a plug. All you have to do is weld the power cord to the circuit board.This kit is available in parts so you can assemble it yourself and build your own tube amp..
