- local pick up only, No shipping.
- manufacturer : FLUXION audio technology
- 2 year labour and parts warranty(tubes are not included)
- tubes included : 12AT7(USA NOS), 6CG7(USSR, NOS), 2 300B(shuguang)
- designed to have long tube life(Pd/tube=32 Watts, 380V X 0.085A=32 Watts. max. Pd=40Watts
- 2 DC Active regulated power supply(by 10A power transistors) for 300B heaters : residual noise is greatly suppressed under 2mV. very very low AC hum noise for direct heated tube amplification.
- as a headphone amplifier : headphone output level is designed for high quality / high impedance headphones such as Beyerdynamic DT-880 250 ohm type. If low impedance HP is used, sound level will be too high at same volume control position. strong intensity of sound and long hour can cause hearing loss.
- HP / SPK switch : when HP switch is turned on, only headphone output is active. however when 16 ohm speaker terminals are connected to speakers, speaker connection will not be disconnected.
- self bias for easy operation
- separated 2 bias check points for accurate tube matching and plate current calculation. ex. if tested bias voltage is 70V, Ip=70 / 0.82 = 85mA(Rk=820 ohm). max. Ip of 300B(self bias)=100mA.
- standby switch : SB switch is installed at front panel to protect high priced tubes.
- continuous output power : 7~8 watts / channel
- total harmonic distortion(THD) : 0.5~2 % at max output power(depends on tubes).
- Frequency response : 20Hz(-1.5dB)~20KHz(-1.5dB), ~30KHz(-3.5dB). See scanned graph
- NFB = 3dB only
- input sensitivity = 230mV
- output impedance = 8 and 16 OHM
- SNR : 70dB(1 : 3100).
- square wave test : no ringing/overshoot means very clean sound reproduction. see photo
- top/front/back panel : 2 / 10 / 2mm thick anodized aluminum, CNC machined.
- wood frame : Canadian natural wood, CNC machined and finger joint finish.
- resistors : metal film type 2 watt(or 1 watt), wirewound type 5 watt. S. Korea made.
- capacitors : metalized polyester film type(0.1uF 600V), electrolytic 100uF 310V, 82uF 450V. S. Korea made. High priced capacitors can be installed by buyer's request(extra charge)
- volume control : ALPS 100KA dual.
- switches : 250V 3A DPDT, Taiwan made.
- power consumption : approx. 150 W. This item supports 120V 60Hz only.
- size : 260(W) x 350(D) x 220(H) mm, H is from bottom to the top of power tubes.
- weight : appr. 12kg
