Class A High-Power Gold Seal KSA100MKII Amplifier Board Hi-Fi Post-Amplifier MK2 Circuit Kits Note: This amplifier board is a loose part without eight pairs of power tubes, you need to assemble yourself KSA100 has two versions, - one is the logo KSA100 version. One is the upgraded version MK2. Most of the versions on the market marked MK2 are false labels, the difference is that the voltage amplifier most MK2 uses 8 medium power field effect tubes per channel, while the non-MK2 version uses only a few small transistors. The difference is that most MK2 voltage amplifiers use eight medium power field-effect tubes per channel, while non-MK2 versions use only a few small transistors. This version uses the standard double differential input, visual difference to see if each board with 4 medium power field effect tubes plus 8 medium power driver tubes will know. With the MK2 version. Not with the ordinary KSA100 version! Product Name: KSA100 MK2 Class A Gold Seal Edition Signal-to-noise ratio: 103dB Harmonic distortion: <0. 008% Rated power: Class A 100W (4 ohm) Class A and B 250W (4 ohm) Some peers false label for 450W Frequency response: 10HZ- -40KHZ Load range: 2 ohm, 4 ohm, 8 ohm, 16 ohm Static current: adjustable, according to heat dissipation can be adjusted to class A or class A and B Power supply range: plus or minus 30V to plus or minus 60V plus 1 group AC 12V to 15V range for protection circuit PCB size: 280mmX113mm Installation accessories: screws, mounting copper column, mica sheet, aluminum angle aluminum All core accessories are high-end fever parts, 718 copper foot fever resistors, Japan Toshiba 2SC2240/970 Pairs of tubes, VIS field effect pairs of tubes, ON's MJL15024/25 gold seal pairs of tubes, MJE15032/33 power pairs of tubes BI U.S. adjustable resistors, Japan Omron relays. Japan fever capacitor, Germany red WIMA fever capacitor Japan high-precision constant-current diodes, etc. Debugging: Adjust the 5K adjustable resistor in the module to make the midpoint output close to 0mV. Note the temperature, the temperature is too high, you need to adjust down 1 point of the voltage drop, but also not that the greater the current sound is better.
