eBay Description Shuguang Audio SG-300B Super Deluxe Version Tube Amplifier Single-Ended Hifi Tube Amp Good Sound Version Comparison: SG-300B Classic Version: (300BG*2,6SN7GT*2, 12AX7B*2, 5U4G*1) SG-300B Deluxe Version: (300B-Z*2, CV181-Z*2, 12AX7-TA*2, WE274*1) SG-300B Super Deluxe Version: (WE300B*2, 6SN7-T*2, 12AX7-TA*2, WE274*1) Description: 1. Advantages in sound quality: Seven tubes are used. High-power rectifier tube is used, mainly to improve sound quality, increase driving force, high power, strong sound field control (sound will not diverge), obvious analysis power, and strong mid-frequency and high-frequency penetration. The dynamic is big, the sense of hierarchy is strong. 2. Newly produced tubes are used. 3. The transformer core is a Japanese Z11 silicon steel sheet. The material used for the transformer is very important. Good material can ensure the sound quality, especially this SG-300B has a sweet voice, strong sound field control, obvious analytical power, strong mid- and high-frequency penetration, large dynamics, and strong sense of hierarchy. 4. Hand-made scaffold welding reduces distributed capacitance, improves high-frequency sound quality, ensures strong sound penetration, and high-frequency threading. 5. Using self-made three-stage continuous push direct-coupled single-ended amplification, the undistorted power reaches 10w, ensuring high thrust, high power, and high dynamics, while the 300B single-ended on the market is generally 8w. 6. Focus on the details. The chassis adopts an all-aluminum chassis with beautiful appearance and reasonable color matching. Transformer’s cover is special-shaped and unique, the inside is a manual scaffolding, using silver-plated wire. The cathode capacitor is an imported capacitor, the cathode resistance is a 50W gold resistor, coupling capacitor for WIMA used, tube The base is a special customized tube base, the potentiometer is a Japanese potentiometer, the switch and ammeter are all customized by Taiwan, and the transformer core is a Japanese Z11 iron core. The perfect combination of classic and modern! The signal input and speaker sockets and other connectors adopt customized plug-ins.
