    ​Features:

    • Handmade, using scaffolding welding
    • using two high quality and wide frequency response EI output transformer
    • Using a customize Z11 core toroidal power transformer
    • Amplification and drive part use SAR4 rectifier .
    • Use 2X12AX7 and 2X12AU7 as amplifiaction,
    • Use special high selected KT88 tube as push pull power amp lamp,providing switch for the triode connnection and ultra-linear connection modes.The triode connection mode is more suitable for the voice and the sound is more soft, delicat as well as nature. The ultra-linear connection is suitable for the big scence, the sound is more open and lively. 
    • It has a pure power amplifier ans it can conncet with an independent pre-amp's signal input.
    • There is a power tube current control button and an electric meter dial.
    • Infrared remote control function
    • Power Mute delay function
    • Selection of Japanese high-grade ALPS motor potentiometer.
    • Easy installation of the plug-type vacuum tube shield

    1. Tube amp must connected with speakers before turning ON. Strictly prohibit send signals to amp without connected loads(speakers) or load short circuit when the switch is ON.

    2. Too high or too low power supply voltage does irreversible harm to the amp,preferably less than 5% of the specified voltage. If your mains voltage exceeds this value, often best to use with the AC power supply.

    3. Temperature is higher when tube amps working, placing attention to ventilation, cooling.

    4. In the boot or just shut down for a period of time (within 30 minutes) Do not spill liquid on the tubes.

    5.  You should take about 100h time to operate the amp.RUN-IN to the amp gives it's best and stable sound.so during the first 100h use time the sound maybe is not the best,you can also use your own run-in method. 

    6. If you donot sure how to plug the tubes, please contact us before try it

    Speakers connection

    All tube amplifier used with stereo mode:  L(left) and R(right) speakers.
    Normally there are 6 speaker cable connectors: +8L, +4L, -0L, -0R, +4R, +8R 

    Example: +8L and -0L are for connecting with your Left 6-8ohms speaker 
    -0R, +4R is for 
    connecting with your Right 4ohms speaker 

     

    Tube amplifier guaranty :

    Tube amplifier Guarantee:  6 months for tubes sold with amplifier, 1 year for the amplifier and PSVANE tube
