The pre-amp tube Description:
6N6T: high mutual conductance (S = 11mA / V), the amplification factor (u = 20), low internal resistance (Ri = 2KΩ) tube.
12AU7: well-known low transconductance, the high resistance of the communication measurement tube.
12AT7: the burning world "quite famous air excellent sense of wideband, low noise

Product Features:
Output transformer use 0.35mm audio-specific silicon silicon steel layer and section wound around technology size is 96mm * 40mm.
Power transformer silicon steel: 114mm * 60mm. High-quality nylon frame, high-purity oxygen-free copper wire.
Taiwan production W.L Wizard potentiometer volume control.
Input within the machine using Teflon silver plated shielded signal lines, strong anti-interference, reduce the transmission missing.
German WIMA red MKP polypropylene coupling.
PCB model using sets of domestic production and some carbon film resistors; scaffolding welding models feature military Dahongpao metal film resistors, carbon film mix.
High-voltage secondary rectifier, 5Z3P * 2 gall rectifier, four imported large filtering capacitors and two inductor filters.
Reference to the improvement of the classic circuit, famous 12AT7 * 2 voltage amplification, 12AU7 * 2 phase inversion, 6N6 * 2 cathode output driven, push-pull class AB amplification. A wider frequency response, phase shift to smaller, higher fidelity.
Transformer with epoxy potting, solid and reliable, high temperature, insulation, moisture, shock absorption and play a role, can greatly reduce the magnetic coupling through the chassis to reduce resonance, and reduce noise.
