Hot! Cheapest ksa50 kell rear amplifier mono power amplifier The strange force KRELL KSA50 class A 50w home amplifier board Technical parameters: Output power: 150W / 4ohm load; (Total harmonic distortion THD + N Speaker Impedance: Available 4-8 ohms. PCB size:. 138 * 56MM Very small, suitable for connecting Power supply: DC Dual 18-50V transformer 200 watts or more, the need to replace withstand higher voltages higher capacitance. Discrete Tube: 2SA1943 2SC5200, classics on the tube (Actual delivery of boards). Introduction: Hong Kong hi-fi magazine editor Chen Yingguang introduced in 1993 a second-hand equipment in the article wrote, many industry insiders believe, KRELL the first KSA50 its culmination, the tone is the most beautiful, which is said mutual Pass confirmed. Taiwanese experts Huang Hongjun Tan old audio equipment when KEELL KSA100 (fan version) when Evaluation:. This is Krell\'s famous for, using pure Class A design, and has caused sensation in the market Appeared on the market because it was Apogee speakers, its low impedance characteristics of the then crew eleven test down, burn hanging by a few points, then the latter can be the perfect driving Apogee level, devaluation Krell. In the past I used Infinity IRS Beta, it has also been responsible for using the Krell KSA 100 bass column, in addition to thrust beyond amazing, the sound texture is also commendable. It sounds quite delicate, very Naiting Strings, nice, warm, grainy texture good piano, voice and various aspects of performance is absolutely top names machine model. This suite of lines from the force KRELL KSA50 handed down generation of machine.Complementary differential input. notice: 1.A piece of circuit board is only one channel, Stereo need two pieces of current board 2.Electricity must be installed before the radiator Debugging steps: 1) after completion of welding with good heat sink (note that the pipe and the heat sink should be insulated handle), adjusting VR2 (5 k precision is adjustable Resistance) makes the static current, about 50 ma VR2 counterclockwise static current, clockwise is reduced.Suggestions on electricity clockwise twist laps before! Safety! Don\'t put wrong resistor! 2) neutral zero, adjust VR1) (20 k closely adjustable resistance, make the output (OUT) of terminal ends (ie, the power output) Close to zero millivolt; More pictures of Amplifier board: Note that this amplifier power is rectified and filtered DC power supply after a double, not directly connected to the transformer oh Recommend shop rectified and filtered with a trumpet-protected power strip: Green 2Pin 5.04MM is mono input terminals: IN GND, Audio input connection Black 2P 8.25MM terminal is Audio output: GND OUT, directly to the speaker Black 3Pin is AC power input terminals: + V GND-V select Dual 18-50V DC voltage. recommended dual 35V DC Higher voltage, then we would replace the high capacitance voltage value
