AC12V-0-AC12V Tone Board Adopts JRC5532 A3 Class A Luxury Tone Board

Features 1 Use Japanese original JRC5532 2 The main filter capacitor adopts imported fever grade ELNA with a capacity of 3300UF 4 and adopts 2A and above rectification to ensure a strong continuous power supply 3 The resistance selects five ring metal resistors and the main circuit uses five ring metal film resistors with an accuracy of ±1 which ensures a good signal to noise ratio of the whole machine 4 The PCB adopts 1 6mm thick double sided board 2 0 oz copper thickness and full tinning process to ensure good passing performance of large and small currents 5 The fully enclosed dust proof potentiometer has more stable performance and is more durable than ordinary potentiometers 6 Class A parallel adjustable regulated power supply has the characteristics of high speed low noise and low internal resistance In terms of noise music detail and sense of extension it is unmatched by series regulated power supplies The performance of the series connected regulated power supply for dynamic loads is not as good as the parallel connection because when the series connected power supply has no load the conduction degree of the regulating tube is very low which is similar to Class B For dynamic loads it needs to accelerate from 0 to 60mA There is a large amount of current sent to the regulating tube which works in Class A and only needs to accelerate from 30mA to 90mA for dynamic loads The response speed of the two is definitely different The wiring layout of t
