For those who have not played the tube and have not heard the charm of the tube can let go and experience and experience! For the xenon tri-tube 80, 90 after the has been very strange, the niobium tripole is the ancestor of the transistor, silicon tube appeared before the tube was once unified, the most common to the old-fashioned semiconductor radio. Now use it to do sound amplifier, soft and sound, delicate sound, has the taste of The ancient, the sound of the tube warm and mellow, delicate thorough, relaxed, endless, quite modal, sound is different from the silicon tube, but also different from the tube is also different from the field effect tube, has its unique flavor and style. The tube sound is thicker than the silicon tube, the reason is charming, but also suitable for its so-called AGC ability, that is, the bias is higher (the greater the current), the greater the HEF, this feature makes the sound of the tube out very expanding force, not simply with the more traditional sound of the bile can be described and compared, for the tube is natural. The line 6 tube amplification, 6 volts DC operating voltage, operating current about a dozen to dozens of MA. The use of foreign FM radio headphones to monitor the amplification line, input 1 volt to 1.5 volts signal voltage, 2 times the voltage gain, not easy to cause the signal top distortion, and modern high-indicator low distortion to enlarge the line taste effect is obviously different, can not be compared!

Need external 6V regulated power supply, line quiet. Affirm: do not match the schematic, voltage 6V regulated power supply, can not be used over voltage, otherwise the burning plate burning pipe. Note: small signal amplification board, the signal is too large easy to appear distorted, the signal input before adding a potopotor, control size, otherwise easy distortion The grid parameters are slightly different. If the component color map, parameters and physical and schematics on the finished plate are different, the receipt will prevail!
