Technical characteristics:
1. Use imported Z11 core pole level isolation cattle and imported EI core high performance broadband output cattle; Using the United States 24AWG single and multi-strand fever wire connection, extreme level isolation cattle effectively alleviate the current impact force, so that low frequency jumping force, control power, more rich image. The materials used in the machine are 100% original imported customized components.
2, special front and rear tube independent double high voltage circuit. Balanced tube life, strong gallbladder flavor,
3, 12AX7 high gain front tube gain factor 100 times, more fresh sound.
4, Two 845 tube rear stage push, high pressure, high power, full sound calm, momentum, delicate open, low frequency unusually strong and powerful, cope with symphony and other large food speakers easily.
5, equipped with BISA current indicator and external BIAS ADJ adjustment function, convenient to monitor the working state and adjust the power tube; Dual function level meter display, pointer with music swing, full of dynamic.
Feature of machine
1, the whole machine adopts large signal and large current building shed small signal circuit board welding
2, using two high quality wide frequency response high sound quality Japanese EI output transformer
3. Use high-power Z11 core ring power transformer specially designed for this machine
4. 12AX7 and 6SN7 vacuum tubes are used for voltage amplification and inverting push, and 845 vacuum tubes are used for AB1 push-pull power amplification; Super linear working mode, sound open, unrestrained, good momentum, suitable for appreciating big scene, big dynamic and other types of music.6, peripheral power tube current adjustment button and current display head
7, with pure post-stage function, can be connected to the independent pre-stage signal input
8, with balanced input function, can access balanced audio source
9, infrared function remote control
10. Mute delay function (about 30 seconds)
11, to the heat engine can open the mute function, during the mute KT150 vacuum tube only the filament heating high voltage circuit does not work
12. Use Japanese ALPS motor potentiometer
13, easy to install plug - in vacuum tube protective cover.
