These cute little guys produce around 40 watts RMS in Ultra-Linear mode or around 20 watts in TRIODE from a quartet of EL84 / 6BQ5 tubes driven by a 6414 dual triode driver and a 12AT7EH input dual triode.

Specifications:

  • Input Tube: 1 x 12AT7EH large plate Eletcro-Harmonix Russian

  • Driver Tube: 1 x 6414 JAN NOS GE or Raytheon branded

  • Output Tubes: 8 x EL84 Ships with Russian NOS EL84M (aka 6Pi14Pi-EB) We are out of Ei 6BQ5.

  • Output Tube Quiescent Standing Current: 25mA

  • Set Bias for 250mVDC measured across each 10 Ohm cathode resistor

  • Input Impedance: 110 kOhm

  • Negative Feedback: MIN= 3dB; STD=6dB; MAX=10dB of global NFB

  • Gain:

    • TRIODE/UL

    • FB MIN: 30.7 dB 32.1 dB

    • FB STD: 28.5 dB 29.1 dB

    • FB MAX: 26.1 dB 27.1 dB

  • Input Sensitivity for Maximum Output Power: defined as input voltage required in order to produce maximum power output reaching 1.5% THD  1KHz

    • TRIODE/UL

    • FB MIN: 175mV 155mV

    • FB STD: 312mV 340mV

    • FB MAX: 480mV 566mV

    • Input Sensitivity for 1W into 8 Ohms: 61mV 53mV

  • Maximum Output Power: defined as power output reaching 1.5% THD  1KHz

    • Signal to Noise Ratio Ref. 1W: Typically 82 dB A-WGT 20-20K

    • Noise Floor: Typically 150µV = -74dBu A-WGT

    • Noise Floor: Typically 650µV = -62dBu unweighted

    • Will Scratch Your Floor: Use pennies under pointed feet to avoid marring cabinetry. Try quarters if you are in upper tax brackets. The bargain performer would be nickels. Paper currency does not function as well. Euro coins work 1.54 times better. Concrete pavers or wooden chopping blocks serve fine for amplifier platforms.

    • Dynamic Range: 83dB

    • THD+Noise  5W: less than 0.15%

    • Frequency Response at full power UL mode w/MAX NFB: 20 Hz to 20 kHz FLAT

    • Frequency Response at 5W into 5 Ohms: 10 Hz to 30 kHz FLAT, -3.75dB  100KHz

    • Recommended Speaker Load: Optimized for 5 Ohms

    • Output Impedance:

      • TRIODE / UL

      • FB MIN: 2.43 Ohms TRIODE; 3.10 Ohms UL

      • FB STD: 1.47 Ohms TRIODE; 1.67 Ohms UL

      • FB MAX: 0.90 Ohms TRIODE; 0.95 Ohms UL

    • Damping Factor:

      • TRIODE / UL

      • FB MIN: 3.29 TRIODE; 2.58 UL

      • FB STD: 5.45 TRIODE; 4.78 UL

      • FB MAX: 8.90 TRIODE; 8.43 UL

    • Maximum Power Consumption (at Full Power): 168 Watts (1.4A  120VAC)

    • Operating Mains Voltage: Factory set for 100V, 120V or 220-240VAC operation for original destination country's mains voltage.

    • Operating Mains Voltage: changeable with power transformer re-wiring and fuse value change.

    • Mains Voltage Frequency: 50 ~ 60 Hz

    • Fuse type and ratings  117 VAC operation:

    • Fuse type and ratings  230 VAC operation:
      MAINS fuse: 1.6 Amp 3AG slow-blow use glass body Littlefuse Series 239

    • B+ Fuse: MDA 400 mA SLO-BLO Ceramic Time-Delay fuse

    • Badge Illumination: Units produced before 3/2003 use 8V, 0.3A "Fuse-Lamp" 1/4" X 1 1/4" - Serial numbers after MAHI036 use LED illumination which probably won't burn out

    • Dimensions: 11" deep x 10" wide x 5" tall

    • Shipping weight each: 18 pounds
