Willsenton R-35i EL34 x4 Tube Amplifier hifi Headphone Amp with Bluetooth

This machine features:
1, pure hand made, the whole machine uses point to point welding
2, using two wide frequency range and good sound quality Japanese EI type output transformer
3. Use high power Z11 iron core EI type power transformer specially designed for this machine
4. Use 12AX7 and 12AU7 vacuum tubes for voltage amplification and phase inversion, use EL34 vacuum tube for AB1 push pull power amplification; provide triode and super linear selection function
The three stage tube works in a soft, pure and smooth sound, suitable for enjoying vocal, string and other types of music;
Ultra linear working style, sound open, unrestrained, good momentum, suitable for enjoying big scenes, big dynamics and other types of music.
5, peripheral power tube current adjustment button and current display header
6, infrared function remote control
7, boot mute delay function (about 30 seconds)
8, Japanese ALPS motor potentiometer
9. Easy to install plug in vacuum tube protection cover

This machine replaces the vacuum tube model with the vacuum tube model.
