The model currently on sale is the New Model upgraded in December 2023.
This amplifier can be used with KT88 or EL34 vacuum tube, and there is a Red selection button on the Back of the amp to switch. The default matching tubes of this machine is KT88. If you need EL34 tubes, please purchase separately.
Can be used as an Integrated amplifier, power amplifier or Headphone amplifier Pure hand-made, the whole machine is welded with scaffolding.
Triode and ultra-linear selection are available, which can be switched by the button on the amplifier. With a remote control,Vacuum tube protective cover,Fuse and an English manual.
We recommend that you spend 100-300 hours to RUN-IN this amplifier to get a better sound. Generally, you could get a better and stable sound after 100 hours, and you could get the best sound after accumulating more than 300 hours.
