NE5532 Class A Tone Board Finished Board Volume Control Board 2×3300UF

Description: Series power supply dynamic load performance did not parallel the good, Because when the series lead regulator power load is low pass degree, B approximation for dynamic load from 0 to accelerate to 60mA, Parallel power constant current source has a large current to the regulator, in the CPI for dynamic load simply accelerate from 30mA to 90mA, both reflect the speed is definitely not the same. The entire circuit board trace layout are very strict and reasonable, the overall PCB traces using a little grounding. Stable, reliable, low-steady solid and strong, very good signal to noise ratio, wide dynamic range; the details clear, excellent transient response, play a variety of music all rise to the occasion at home playback environment has a very good performance. Using original NE5532. Correction capacitors imported Siemens, lower distortion and better effects, the main filter capacitor using imported chemical capacity 2 × 3300UF, using 3A and above rectifier, ensure strong support for a steady stream of power. Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio. 1.6mm thick sheet using double-sided PCB, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. PCB-class quality. Fully enclosed dust-proof potentiometer, the performance is more stable, more durable than ordinary potentiometer PCB size：146*68MM n voltage：AC12V-0-AC12V or 15V potentionmeter ( left - right): low tone, middle tone, high tone, main volume control Package : 1 pc NE5532 Class A Tone Board Finished Board Volume Control Board 2×3300UF
