The 22 (tu:tu) Hybrid Tube Amp is a work of art. This Japanese made amp, designed by Koichi Futatsumata, it is a 12W per channel amplifier that has a 6SN7 vacuum tube preamp stage feeding a solid-state output section.

With the pre-amplifier tube front end, this little amplifier provides a rich, warm tube sound, with a contemporary appearance.  Read what WIRED magazine had to say about it.

Elekit (EK Japan Co. LTD) has been producing electronics kits since the early 1970's. While their main focus has always been educational kits, more recently they started to offer hifi audio amplifier kits and some complete amps like this one. They have some fantastic vacuum tube amps and headphone amplifiers.

Functions Include:
  • As for the input terminals, PHONE IN is equipped in addition to conventional LINE IN. This PHONE IN has the characteristics such as high sensitivity and low impedance that correspond to headphone output of portable audio players now predominant as a sound source device.
  • With these two input terminals, LINE IN and PHONE IN, you can enjoy mixing two different sound sources.
  • The vacuum tube circuit and the output amplifier circuit are automatically shut down and it shifts to SLEEP mode when there are no sound signals for more than 10 minutes, therefore you will never worry about forgetting to turn off. When a sound signal is input again while it is in SLEEP mode, it will reboot automatically. (It takes 20~30 seconds for the vacuum tubes to warm up.)
  • The provided AC adapter has 100~240V specification so that it can be used in most of the countries. (A power plug corresponding to your country’s specification is required separately.)
  • Includes Electro Harmonix 6SN7EH tubes
