Basic technical parameters:

  • Tubes: 
           Rectifier tube: SHUGUANG 5Z3PAT x 1
           Voltage tube: SHUGUANG 6N8P x 2

           Power tubes: 2 x PSVANE KT88   
  • Output power: 12W * 2 (ultra-linear connected)
  • Frequency response: 20Hz-20KHz
  • Output Impedance: 4ohms - 8ohms
  • Power transformer: Japan's Z11 0.35mm 105*60 240W, HIFI hademad quality
  • Output transformer: Japan's Z11 0.35mm 86*40 , HIFI hademad quality
  • Total Harmonic Distortion: 0.5% (1kHz)
  • Input Impedance: 100Kohm
  • Input Sensitivity: 500mV--2000mV
  • SNR: 88dB
  • Size (W x D x H): 370mm x 290mm x 60mm(155mm max)
  • Net weight: 18 kg     
  • Input voltage: 110-240V 50-60hz
  • Front panel color: Silver


  • 2 Milliammeters independently in real-time display  your power tubes emmsion values, assure your power tube have a good value, and chang the value if you want for a better "Overclocking"(do not recommande for junoir ) 
  • 3 RCA analog source inputs with input switche on front panel
  • Switch inputs in front panel for eliminate circuit interference
  • Change to use EL34 tube by adjuste Gate negative regulable by -VB1(left) and -VB2(left), it will change the emmission current value for all beam tetrode tube (should consult us before to adjust it)
  • Voltage tubes midpoint noise adjustable by hum1(left) and hum2(right),should consult us before to adjust it
  • Tubes are strict paired
  • HUM1 and HUM2 is for change filament center to reduice power tube noise(if it has, but do not change it for new amplifier and tube)
  • Handmade Point to Point scaffolding welding
  • Machines with four audio resource switching circuit
  • Inspire Poland’s famous kt88 tube amplifier circuit, the circuit is matured and the sound is great
  • Classical and also modern design
  • Bias value is adjustable, and you can check direclty the emission current with Milliammeter
    , so you can use KT88, 6650, 6L6, EL34 tube with different bias value


This tube amp is one the most popular tube amps created by "Veteran",  he inspire Poland’s famous classic amplifier to create this high level KT88 tube amp. it's used for 10-150w HIFI Speakers to all music type, soft voice and surging bass are its special feature.





Next pictures are taken take with a black version,  it is just for showing the function , the transformers cover is different than silver version:


Bias value is adjustable by -VB1 and -VB2 , and you can check direclty the emission current with mA-meter    (Milliammeter)    , so you can use KT88, 6650, 6L6, EL34 tube with different bias value:
