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.
