• High-quality DIY Amplifier Kit: This Vacuum Tube Amplifier Kit is designed for audio enthusiasts who enjoy building their own equipment. The four pins of rectifier respectively in parallel connect with decoupling capacitor, which can effectively eliminate the high frequency interference of AC power grid. With its superior quality components and easy-to-follow instructions, this kit allows you to create your own high-performance tube amp from scratch.
• Exceptional Sound Performance: Experience the warm and rich sound that only vacuum tube amplifiers can provide. The carefully selected tubes and pre-amplifier board ensure low noise, as well as excellent performance in low, middle, and high pitch ranges. Take your home audio or guitar playing to the next level with this exceptional amplifier kit.
• Versatile Audio Input and Output Options: The sockets provide convenient audio input connections for various devices, allowing you to connect your favorite music sources seamlessly. The 3P terminal audio output ensures compatibility with different speaker systems, delivering powerful and clear sound reproduction. And the item has better performance.The chip has high conversion rate and strong drive ability. The frequency band is wide and noise is very small.
• Reliable and Safe Power Supply Requirements: Please note that this amplifier board cannot be powered directly by a 12V battery or DC source. It requires positive and negative double DC power sources or a dedicated AC 12V transformer power supply for optimal performance and safety. Rest assured knowing that the power supply requirements have been carefully designed to protect both the amplifier and your audio equipment.
• Complete DIY Set and Helpful Tips: This package includes everything you need to assemble your own pre-amplifier board, making it easier than ever to create your dream tube amplifier. Additionally, we provide helpful tips and guidelines to ensure a smooth assembly process. Please allow for a small measurement error and slight color variation due to manual measurement and individual monitor settings.

Description: High quality filter power supply. The four pins of rectifier respectively in parallel connect with decoupling capacitor, which can effectively eliminate the high frequency interference of AC power grid. Two 2200UF25V electrolytic capacitor filter the negative power supply, then stabilize voltage with 7815 and 7915 double DC power supply. Now the clutter interference of power grid is very small and the voltage is quite stable. So the item has better performance.The chip has high conversion rate and strong drive ability. The frequency band is wide and noise is very small.  Features: 1, Power supply circuit adopts full bridge rectifier. 2, Effectively eliminate the high frequency interference of AC power grid. 3, Chip has high conversion rate and strong drive ability. 4, Better performance,noise is very small. 5, Can not use 12 V battery or DC directly as power supply.  Specifications: Working Voltage: AC double 15 V (10 W) Audio Input: sockets Audio Output: 3P terminal Input Voltage: 3P terminal Size: 110 mm x 54 mm x 22 mm  Package includes: 1 x Pre-amplifier Board DIY Set  Note: 1, The amplifier board can not use 12 V battery or DC directly as power supply. Power supply should be positive and negative double DC power sources, or special AC 12 V transformer power supply. 2, This item need a power amplifier to drive speaker. 3, Please allow 1-3 mm error due to manual measurement. Thanks for your understanding. 4, Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.
