Queenway AB1-KT88I Push-Pull Vacuum Amp Dual Mode Triode/Ultra Linear Psvane KT88 Power Tube HiFi Valve Amplifier With Remote

Please prepare a CR2032 battery for the remote of KT88 amplifier, as the plane shipping with a little battery is very expensive!

Features of this machine:

1. Well-designed appearance, adopting modern industrial product design ideas, simple and elegant, internal point-to-point wiring, manual welding.

2. Using four KT88 vacuum tubes of PSVANE with customized parameters as AB1 push-pull amplifier

3. The preamp uses two 6H2C and 6N7P vacuum tubes.

4. Two high-quality broadband response and high-quality EI output transformers are used.

5. External user offset adjustments can be monitored via the offset meter on top of the amplifier.

6.CNC all-aluminum processing remote control, start mute delay function (about 20 seconds)

7. High quality Japanese ALPS motor potentiometer.

8. Equipped with an easy-to-install tube cover for protection.

9. High-quality capacitors are used in key positions of the circuit, and the sound quality is better.

10. Using the audio resistors produced by Visa and Philips in the United States

11. Provide triode and super linear selection function. Triode working mode, the sound is soft, pure and smooth, suitable for listening to vocals, strings and other types of music; super-linear working mode, the sound is open, unrestrained, good momentum, suitable for enjoying large scenes, big dynamic and other types of music.
