M100-10 signature 10th anniversary commemorative signature version of tube integrated power amplifier

In 2004, Ober's 10th anniversary commemorative product.

Unlike the classic M100PLUS, the voltage amplifier stage does not use the SRPP circuit. It uses a 12AT7 to be divided into two halves. The low internal resistance and high screen consumption 12BH7 replaces the 6N8P for long-tail reverse phase drive. Instead of using a fixed grid bias voltage, it uses a self-sufficient bias voltage method, which is convenient for tube replacement and does not require adjustment, which is in line with modern living habits. The high-voltage part adopts the three measures of mixed rectification of electron tubes and transistors to make the sound more charming and the high frequency more detailed. Make good use of the tube, and the sound is guaranteed. The power part of the amplifier has a great influence on the sound, which is already well known. In the 10th anniversary commemorative signature machine, in addition to the use of electronic tubes for the rectification, all the electrolytic capacitors with good musical properties are also used for the filter electrolysis. Such an investment has brought a lot of return. The output transformer is the soul of the electronic tube machine. The design has been used for more than ten years. After many years of tests, its musical sense is strong and has been recognized by users at home and abroad. The new design in 2011 added negative feedback winding, the phase-frequency characteristic is more superior, the performance is that the sound field and positioning are more accurate in the sense of hearing, and the full-frequency distortion is smaller.
