A1 Preamp Tone Board Power Amplifier Board

Description

• Power supply voltage: AC 12V-18V
• PCB size: 4.6 x 2.6 inches (117 x 65 mm) (width without potentiometer handle length)
• Potentiometer distance: Left to right 24MM * 24MM * 35MM (24)
• PCB adopts a double-sided sheet with 0.06 inch (1.6 mm) thickness of 2.0 oz copper thickness, and full tin spray process to ensure good passage performance of high current and low current. PCB Quality
• The resistor uses 5-ring metal resistors and the main circuit adopts 5-ring metal film resistors with 1% accuracy, so the signal to noise ratio is good throughout the machine

Product Details:
1. Use original JRC5532
2. Adopts the main circuit of the electrolytic capacitor signal, the main filter capacitor adopts 470UF * 14, ensuring strong and continuous power support.
3. The resistor adopts 5 ring metal resistor, the main circuit adopts 5 ring metal film resistor with 1% accuracy, so the signal to noise ratio of the whole machine.
4. The left and right channel input coupling capacitors adopt 2.2UF coupling, which makes the treble range clearer, and the sound is sweeter. More treble and bass!
5. PCB adopts a double-sided sheet with 0.06 inch (1.6 mm) thickness of 2.0 oz copper thickness, and full tin spray process to ensure good passage performance of high current and low current. PCB Quality
6. Using fully sealed dustproof potentiometer, more stable and more durable than normal potentiometers.
7. The entire circuit board layout is very strict and rational. The work is stable and reliable, the low frequency is stable and powerful, the signal to noise ratio is very good, and the dynamic range is wider. The details are clear, transient response, easy to play all kinds of music and performs very well in your home playing environment.
8. Front stage has magnification switch, can be switched from 3.5x to 7x The board has an opamp-amp socket, allowing you to freely change and upgrade your opp amp according to your hobbies, making it flexible and convenient to use for a variety of listening senses.
