BRZHIFI PAP-711 Field Effect Tube Class A Preamplifier 220V HiFi Power Amplifier

Description: Description BRZHIFI PAP-711 Field Effect Tube Class A Preamplifier 220V HiFi Power Amplifier Reference Circuit for SANSUI 711 Description: - The circuit reference is from the SANSUI circuit, which uses 2SK389 twin field-effect transistor differential input. The sound is mellow and durable, with good delicate balance, very similar to the style of a biliary machine. JFET truly has electronic tube sound. Due to the pure thickness and sweet sound of electronic tubes, as well as the characteristics of large dynamic range and ultra-low distortion, field-effect power transistors quickly became popular in the audio industry. This device uses field-effect transistors as the input stage, which can easily meet the most demanding audio application requirements and is suitable for professional and high-end audio systems. Features: - The input differential circuit uses the original 2SK389-BL twin JFET transistor for Toshiba, paired with 2SC3381/2SA1349 bipolar transistor for Toshiba, to present a natural and realistic listening experience. The high-frequency is gentle and pleasant, the mid-frequency is warm and sweet, and the low-frequency is rich. - Field effect transistor differential input - High and low frequency adjustment function - Class A linear power supply + electronic filtering - Stereo fully discrete circuit symmetrical design - Dual transformer power supply - Column filtering capacitor - The power supply circuit, rectification and filtering, amplification and tone circuits are independent and do not interfere with each other. - Pure Class A circuit+electronic filtering, making sound localization more accurate, with clear separation and details. - ALPS27 potentiometer, high precision, low noise, wear-resistant. - Gold plated RCA, low internal resistance, high wear resistance, and oxidation resistance. - Can be used with different transistor post amplifiers and vacuum tube post amplifiers.
