1 Pair of KSA50 Toshiba Tube Adjustable Class A Power Amplifier Board

1 Pair of KSA50 Toshiba Tube Adjustable Class A Power Amplifier Board. Use original Toshiba 2SA1943/2SC5200 and MJE15034/MJE15035. The inter-stage coupling capacitor adopts WIMA capacitor 1UF, the sound is natural and the sound field is wide. High-precision cylindrical color ring chip resistors are used for the 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.

The PCB adopts a 1.6mm thick double-sided board and a 2.0 oz thick copper spray tinning process to ensure good passing performance of large and small currents. The feature of this board is the use of advanced speaker protection circuit, which effectively eliminates the impact sound of turning on and off and the DC output protection function, making your speakers safer. The wiring layout of the whole circuit board is quite rigorous and reasonable, and the whole PCB wiring adopts one-point grounding method. Input voltage: plus or minus 30V-50V DC, AC 12V-15V (a single group, two channels in two groups). It is recommended to use +-45V.

Output power: Class A 50W+50W undistorted power, Class A and B is 250W+250W undistorted power output. The red light will be on after power on, and the green light will be on for 3-5 seconds when the circuit is normal.
