One Pair L12-2 Dual Channels Ultra-low Distortion Audio Amplifier Claic AMP DIY KIT/Finished Board

Note:

There are tow choices for your: ① DIY Kits include all the L12-2 dual channel AMP components which need to solder by yourself; ② Finished boards L12-2 dual channel AMP which will be rigorously tested before delivery to you;

Features:

◆ L12-2 is mainly used for monitoring and has ultralow distortion, but the lowest distortion does not mean that it may be the best listening amplifier, so it is more suitable for profeional users who have very high accuracy requirements for details. ◆This is not a warm-sounding amplifier. If you are looking for a very low distortion amplifier with clean, detailed sound, you will love it. ◆ L12-2 has been used by thousands of users since 2006, all of which reflect very well. It is the claic model in the L series and have the best stable and reliable performance. ◆ Our L series amplifiers are authentic and strictly be tested with various instruments, not like the imitation sold by others merchant which may have high quality risk;

Parameters:

● Power = 120W / 8R + -50V voltage 200W 4R + -50V voltage ● THD 200, 8ohm load ● Input sensitivity = 1.6V output 120W 8R ● Frequency response range = 15HZ-50K HZ (-3DB) ● 20HZ * 20K HZ = -0.02 DB ● Quiescent current = 80MA ● Voltage use range = DC + -12V to + -55V ● Voltage magnification = 31 times ● Transformer Parameters: AC 24-0-24V

Specification:

▲ uses 2MM thiened material 75 UM thiened copper film. ▲ The small signal tube uses the TOSHIBA low noise tube, and the ON low noise tube is used as the current source and voltage amplifier. ▲ The output tube adopts the Sanken ultra-high frequency FT 70M, multi-emitter LAPT audio famous tube. 2SA1186 2SC2837, two pairs of output tubes per channel. ▲s are genuine licensed, Transistors use TOSHIBA ONSEMI SANKEN authentic licensed, quality aurance.

Test Chart:

Input signal-THD + N test When the input voltage is 700MV, the output voltage is about 23VPP and the load is an 8-ohm . The test below: Use 8 ohm 1000W power .

THD + N ≈ 0.0009%

Frequency response:20HZ-20KHZ
