Description

1. This is assembled board and tested well, just need to connect power cord, audio input and output cable. 2. Homemade shell must be open enough heat emission holes, preferably 50%, at least 30% of the shell room for heat dissipation, it matters the service life of the tube amplifier. Product Parameters: - Voltage amplification tube: 2pcs 6J1 (can be replaced by WE403/CV4010/6AK5/EF95) - Power amplifier tube: 2pcs 6P6P (can be replaced by 6V6) - Input impedance: 10KΩ - Output impedance: 4Ω/6Ω/8Ω/16Ω - Output power: 3W+3W - Frequency response: 30-40KHz (-1dB) - Input sensitivity: 500mV - Signal to noise ratio: -80dB/3W - Residual noise: <0.5mVac - Input AC working voltage: 85-264Vac (Global) - Current consumption power: 36W - Net weight: 1.1kg Premium Components: - Output transformer made of Z11 silicon steel sheet and oxygen-free enameled wire - Japanese potentiometer - German coupling - Schottky diode - High quality diode - Japan high frequency low resistance 105-degree capacitor - High voltage controller Attention: Your self-made shell must have enough heat dissipation holes. It is recommended that 50% of the shell area is uses as dissipation holes, and at least 30% of the area should be used as heat dissipation holes. The life of the machine with a good heat dissipation hole can exceed 10 years. The life of the machine without cooling holes or unreasonable cooling holes may not exceed 1 year! Package Included: - 1 x Set of Tube Power Amplifier
