Maintenance Information: 2022.2.15 Maintained (broken stator repair, leveling the step of the contact part with a water grinding wheel, broken flat cable replacement, damaged board pattern, through hole Full correction, all soldering rework correction, input/output terminal function test, no abnormality, no physical characteristic test abnormality (gain: 17dB, maximum output: 14V or more, distortion ratio: 0.015% @1V, 1kHz, residual noise: - 90dB or less @A network, CA test. Note: Please be careful when using X-balanced power amplifiers, etc. This unit is a normal unbalanced amplifier, and it is a simple output system that simply hangs the #3 terminal with a resistor. (Inverted output does not come out) Similarly, the #3 terminal is only hung with a resistor, so if everything is balanced connected, the sound will be quite low for pin input and output, but this is the power of the product.) 2018.3.26 Maintained (Capacitor deterioration replacement.
