Product Details:
6SN7 is a typical low-frequency bipolar transistor Unlike high-frequency bipolar transistors (such as 6N3) and general-purpose bipolar transistors (such as 6N1), the main characteristics are moderate amplification factor, low transconductance, but high screen consumption and high screen voltage. This electronic tube has a rich sound and is relatively suitable for voltage amplification due to its low price The high gate bias of this electronic tube is suitable for signal sources with large dynamics.
1:) 5U4G rectifier tube X1.6SN7 amplifier tube X1
2:) 60W pure copper wire power transformer The 10H 80MA high inductance choke coil (EI48X30) and the power transformer casing are fully shielded, resulting in minimal magnetic leakage.
3:) 33UF Japanese Rubycon capacitor * 2.100UF Japanese Rubycon low resistance capacitor * 2.A CLRC filtering circuit is composed of a 0.1UF thin film safety capacitor and a 10H choke coil.Small ripple, quiet background
4:) Dual 160V 150MA high voltage power supply, 6SN7 6.3V 1A AC power supply, two filament balanced resistors grounded, effectively reducing noise.
5:) Tokyo Electronics TE 2UF MKP film capacitor in parallel with 0.01UF Fairchild capacitor from the United States, with excellent high and low frequency performance.
6:) Japanese ALPS 16 potentiometer.
7:) 1.6mm thick double-sided copper-clad PCB One point grounding design, bottom noise within 2MV.
8:) Famous brand copper foot metal film precision resistor+carbon film warm sound resistor.
