Description

Specifications: Type: 6J1 tube (substitution model 6AK5, 6AU6, 5654 etc.) Channel Types: 2.0 / stereo Voltage & Current: AC12V 0.8A or above Power Interface: 5.5 * 2.5 plug Circuit Board Size: 77 x 75mm / 3.03 x 2.95" Instruction: 1, AC 12V Input: using DC 5.5*2.1 socket and AC 12V transformer, you can also use AC 12V transformer without plug, just need to weld the power cord onto the circuit board. DC power input can not be used, or it will not work. 2, Sound Channel Input: Connected to mobile phone, computer, MP3, MP4 and many other music players. 3, Sound Channel Output: Connected to the audio signal input of power amplifier. 4, Power Switch/Volume Knob: Rotate the knob anticlockwise to turn down volume, and continue rotating until you hear the sound "tick" to power off. Rotate the knob clockwise until you hear the sound "tick" to power on and continue rotating to turn up volume.

Tube amplifiers produce a warmer or more 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. 【Customer Service】 Thincol has always strived to provide customers with high quality products and outstanding customer service.
