HIFI Preamplifier MBL6010 D Black Gold Edition

Zelfbouw voorversterker, gebaseerd op de MBL6010 met 4x JRC5534 Opamps. Zonder potmeter.

Is enough to make an all the enthusiast's attention, because the German MBL6010D it from the world's three famous before -- the price of 10 million yuan.The front line and the original machine main put most consistent with the original materials, materials and as close as possible to the original machine. The famous have a fever op AD797, and using direct coupled circuit, the excellent characteristics of AD797 full play The 1 operational amplifier AD797 is very good, the circuit design for AD797 optimization 2 play circuit is power play, MBL circuit to supply details attached great importance, a per amplifier decoupling, is composed of different sizes of 8 single capacitor, respectively is 220uF 104 (or 224 102 103. The different frequency weak audio to be given full play 3 of the whole DC, without any isolation capacitance. Due to 6 precision collocation adjustable resistor. Each circuit has a separate ground, unlike other versions of the same MBL. Optional floor together, it will affect the degree of separation The use of points: Magnification of circuit setting value of magnification of over 10 times according to the original machine, you can modify the 3-5 times if you feel too much, the first stage of the feedback resistor 220 can be changed to 470--1K. The power supply is adjusted to +_17V or +_15V are fourth feet seventh feet =+17V =-17V operational amplifier After adjusting the power supply can be single Op Amp Plug, and the other in adjustment of the corresponding is adjustable, so output (OP AMP 6 feet) is closest to the 0MV It is recommended to use AD797 amplifier can also choose NE5534 LME49710 The size of PCB is 147X95MM
