Description: Ntroduction: Regarding the clone version of Accuphase E210, we made it in 2009, but since the CLONE version is completely based on the original machine PCB, and all the parameters of the components are not changed, it was limited by the original machine and DIY component brand and model. And the parameters are not the same. Therefore, the production results are not ideal. After 10 years, now we have finally made it possible to ensure that the original circuit remains unchanged and measure according to the components actually used by DIY. It also includes trying out the comparison of various components, and finally it is reasonable to make the sound performance close to the original machine, but in the appearance we changed it, unlike the original machine. This is DIY Accuphase E210 modified version. We believe that the imitation of the famous machine is to optimize the performance under the same circuit architecture, so that the performance is close to the original machine is the fundamental purpose of DIY. Rather than it looks a lot like the original machine, but the sound performance indicators are far apart. Even products with unqualified performance. During the test we used an oscilloscope and Audio Precision 2 for comparative experimental measurements. After more than ten repeated revisions, the current version was obtained. In the production, we first use the oscilloscope to measure. In the test, we can observe whether the waveform of the amplifier is normal and whether there is obvious oscillation or deformation. Then pass the correction component and parameters. Make the amplifier waveform stable. Basic parameters: Input voltage range: DC +/-25V --- DC +/-55V (recommended voltage DC+ /-40V) Output power RMS: 50 ---150W 8 ohm Output voltage gain: Pure post-output VOLTAGE GAIN=18 times Preamplifier + power amplifier combined output voltage gain (switchable with preamplifier output mode) = 100 times Switch pin PREAMP OFF: 1---2 is pure post-stage output, PREAMP ON = 2---3 preamplifier + power amplifier combined output Frequency response range: 20Hz -- 20KHz (-0.1 dB). 10 Hz-30K Hz -0.2dB THD+N: 0.005% - 0.008% 15W output, 8 ohm load 20Hz---20KHz SR: 20V/US Damping coefficient: 100 Radiator recommended size: Mono >200g PCB Size: 82mm * 76mm NOTE: This is a finished board with an adjustment test OK.
