Description Single-end Class A 6F3+300B Tube Amplifier Kit Power Amplifier DIY Parts
Specification:
Wight: 17kg
Power: 7.5W
Power consumption: 160W
Features:
1. The internal resistance of 300B is only 800 ohms, and the damping coefficient is very good.
2. The 300B tube is the best way to reflect the original atmosphere of the music, because the characteristic curve of the tube is very well distributed, coupled with the second harmonic hearing, the mouth shape of the singer, the low frequency tension of the chest resonance and dynamic.
3. The sound of 300B amplifier is more vivid and full of music. This 300B kit has unique acoustic and electrical regulations from the design to the selection of the output cattle.
4. 6F3 is a partial gate composite tube, which is equivalent to a 12ax7+6p14. The performance is extremely excellent, especially connected as a 3 pole tube. The output internal resistance is particularly low, and the linearity is good.
5. For the consideration of sound and stability, a large loop feedback is used to improve the weakness of the low frequency of the tube, so that the internal resistance of the 300B amplifier must be lower, and the overall balance of the sound can be achieved.
