HiFi 6P1 Vacuum Tube Amplifier w/6E2 Level Meter Single-ended Class A Power Amp

Item description

Warm tips:
 
1. For DIY KIT version, we will provide assembly guidance in detail but still needs you have some welding ability and electronic knowledge to solder all components, or else please buy assembled version.
 
2. When testing the tube amp, please connect its output to speakers before turning it on, or else the output transformer or vacuum tubes may be damaged, Douk Audio is not responsible for this.
 
3. Recommend to connect pure audio source such as CD player, DAC or computers etc., and two-divided-frequency speakers whose impedance is 4-8Ω and sensitivity above 89dB.
Features
  • Vacuum tube combination design, adopting 5U4C tube as rectifier, 2PCS 6N2 to push 4PCS 6P1 vaccum tubes in parallel as single-ended class A circuit, 6.8W+6.8W output power. Low, mid and high frequency are very balanced in overall, powerful in low, warm and mellow in mid, well-arranged in high, all details can be truly reproduced.
  • 6E2 vacuum tube as sound level indicator, the green light feels soft and charming, also with 2PCS Taiwan-produced VU meter, dynamic pointers swing under warm orange light, with strong vintage feelings to dynamically decorate your auditory feast.
  • Advanced PCB board and installation technology, the filament of tubes are connected by AC twisted pair, no background noise can be heared even you are very close to the speakers, as quiet as it has been shutdown.
  • Perfect design in circuit and function, multistage capacitor filtering in power part to ensure stable work and no distortion of preamplifcatoin part even at high output; with independent level amplitude potentiometer, to adjust the gain of input signal, that is the swing range of pointer to get differnt display effects.
  • High-quality components are used to guarantee the sound quality and long time stable work:
Power transformer and single-ended transformer are all made of imported EI iron core silicon steel sheet.
Imported EI iron core high efficiency power transformer, imported wide frequency response EI type single-ended transformer,
Taiwan-produced 16-type B100K duplex step-by-step potentiomete, the position is clear and the L/R channels are balanced.
Germany WIMA or CBB thin-film coupling capacitors, high temperature resistant high frequency electrolytic filter capacitors,
High-precision metal film resistance and large power wire-wound resistance.
Telfon high-temperature-resistant wire for wiring, pure copper terminals.
Customized CNC machined aluminum alloy chassis, and 30mm solid pure aluminum volume knobs etc.
