High-power high-current output load. Each channel 2 of ON Semiconductor original power tubes 2SA1943/2SC5200, the maximum load current is 20A. Voltage support a wide range of installation of each channel can be any two pairs, four pairs of high-power tube. Standard suite of high-power tube per channel 2. Dual AC power range is 12V to AC dual 45V. Proposed dual-voltage AC 36V. Parameter: Power :200W8R 350W4R DC ±65V THD = 0.009% 1K HZ 50W 8R SR = 35V / US Noise 92DBU EIN = 114 DB Frequency Response 20-20KHZ ±0.5 DB 34 times the voltage gain All resistors are precision 1% precision resistors copper feet, including the output of high-power high-precision resistors are used. Double-sided FR4 PCB 2MM thick plate, 75 UM thick copper wire. All capacitors are imported original. Four pairs per channel audio power tubes imported original ONSEMI. High-quality NIPPON CHIEMI-CON series of high-grade LOW ESR decoupling capacitors. And nichicon or RUBYCON series. Romote the use of tubes and high-power tube ONSEMI NJW0302G NJW0281G Toshiba A1930 C5171 and audio-specific import original transistor. Suite two boards, one board a channel. L20 must use the original transistor, not free to replace other brands and models. Square-wave test Sine wave output +-60V, load 6.6 Europe, the output power of 270WThe selection of authentic licensed original transistor with TOSHIBA ONSEMI, quality assurance.
