Feature

●Pre-level is to use the 6J1 Heating Tube Gallack, before class: Simulator Music X X-10D circuit principle design, reasonable to optimize and more stable than the original machine performance, so the tube playing is increased by 10%. This machine uses dual AC 18v input, so you dont have to search for high voltage power supply. The board comes with a boost for fun with low voltage power and allows you to enjoy the appeal of high voltage tubes
●Before the output level automatically switches to promote the headset or press the rear 1875 amplifier, i.e. after inserting the headset, the amplifier without output will accelerate the output of the amplifier without inserting the headset
●POWER WORKS: Power supply, tube filament begins to heat up, then the boost from zero voltage begins and other tube filaments get hot, and the boost is complete so this is the same as the gallle rectifier, 4 470UF condenser filters are very clean, the excellent power system does not change the sound and the filament is 12V power, the need for 2 tube filament is in a series and the use can also reduce noise
●This product uses a 6j1 tube to run a pre-level 1875 amplifier with amplifier function. After the 6j1 tube bufferer, it can significantly reduce the "digital taste" and "transistor sound" so the sound will be sweeter and softer as the whole sound system produces a sweet natural "gallop" Tda7294 is better than the average 3886
●The output of sound is a little smaller than the digital sound source, generally thrust, if your friend can accept this method, the output of the product is also available. Next, after the sound source treatment of this product, the headset sound will be tried with sweet and delicate "gallop". The headphone output function can also be used to achieve output levels. Then use it after the amplifier


Description

Bopfimer Color: Green
Material: Metal
After Class 1875t Amplifier: 1875T Classic Design in Europe and America! The wiring is affordable! Outstanding performance! Desired by DIY enthusiasts! The introduction of the 6j1 tube is to promote sweeter, beautiful sound with the introduction of the 6j1 tube to not only retain the original performance assumption, but also strengthen the original components of the O.
Power supply voltage: default dual AC 18v / current 3A, power 60w or more (Maximum voltage must not exceed dual AC 19V, can not lower 18v Otherwise, the tube point is not bright, so the sound will be distorted. You need to use AC 12v to change the wire back resistance if needed. 2.2. For Europe, the output power of the amplifier will be slightly lower)
Amplifier/Front Output: Approx. 0.8 times magnification (you can try to use the amplifier function, and promote the high sensitivity of the headset, general thrust, and the amplifier output can also be used to the current level of functionality and drive the output. Other amplifiers and tube tastes are included).
1875T Amplifier Output Power: Standard 20W (30W max)
Speaker Impedance: 4Ω-8Ω
Total Harmonic Distortion: Less than 0.04%
Signal-to-Noise Ratio: 105dB
Frequency Response: 14Hz-100z (maximum range of 3.29Hz-482.29z by high and low circuit count)

Package Includes: 1 x 1875t Power Amplifier Board Kit
