Описание
This product uses the lm1875 pre-amplifier tube 6j1 with amplifier function. After the 6j1 tube buffer, the "digital taste" and "transistor sound" can be greatly reduced, so that the whole sound system brings sweet natural "bile", the sound is more sweet, mellow. Than the average lm3886, tda7294 is better to listen to. Preliminary level is the use of 6J1 fever gallbladder before the class: X-10D music fax machine simulation circuit diagram, reasonable for optimization, more stable than the original machine performance, incrd playback tube by 10 percent. This machine uses dual 18V AC input, no need to worry about finding a high voltage power layer. The board comes with amplification so that you can enjoy the charm of the high voltage tube. power layer, the tube filament began to heat up, then the pulse from zero voltage began to rise, and the other tube filament is hot, the boost has just ended, so the same with bile rectification, 4,470uF. The condenser filter is very clean. , excellent power layer system will not have sound exchange, the filament is a 12V DC power layer, two tube filaments must be connected in series, the use of DC filament is also designed to reduce noise. Before the output level, automatically switch to the headset advance or press lm1875 rear amplifier, that is, after the headset is inserted, the amplifier without output, do not insert the headset, this will advance the amplifier output. The sound output is slightly smaller than the digital audio source, pull at all, if the pt ends can accept this path, but also the output of the product. Then you can try, after processing the sound source of this product, the sound of the headset will be a kind of sweet and delicate "bile". The headphone output function can also be used to create an output level, and then another after the amplifier. Color: green Material: metal After lm1875t class amplifier: Europe and the United States LM1875T classic design! Reasonable Wiring! Outstanding performance! Looking for DIY lovers! Store to keep all the original alignment, keep the original performance of the room, and strengthen the original components Oh, the introduction of the 6j1 tube to enhance the sound more sweet and beautiful! Power supply voltage: default double AC 18V / current 3A, power 60W or more (the maximum voltage can not exceed double AC 19V and less than 18V, otherwise the tube point is not bright, sound distortion. If you need to use AC 12V, you need to modify the wire step-down resistor. For Europe 2.2 output power amplifier will be slightly lower) Amplifier / front output: an increase of about 0.8 times (you can try to use the amplifier function, you can increase the high sensitivity of the headset, pull in general, the amplifier output can also
