Description
The amplifier stage is composed of a standard class Class A power amplifier circuit. The amplifier tube to screen load impedance is 6KΩ, and the plate voltage is 375V.
Using only the gate negative bias mode, the zero-signal push-pull two-plate electrode power is 85mA, and the large screen current increases to 150mA. Rated output power is 16W, high power can reach 22W.
4.0 Bluetooth HiFi Module
The amplifier supports Bluetooth input and can be easily paired with Android, iPhone, iPad, Tablet PC and other devices.
Support headphones to switch output, is a tube headphone amp
Bluetooth tube amplifier features:
1. Pure vacuum tube, pure hand-made, the whole machine adopts scaffolding welding.
2. Use two high quality wide frequency response EI output transformers.
3. Use an EI-type high-quality audio-dedicated power transformer developed specifically for this purpose.
In the previous stage, two 6N1 vacuum tubes and one 12AX7 vacuum tube were used.
5. Two EL34 vacuum tubes were used as AB1 push-pull power amplification in the later stage.
6. With headphone output function. Directly connected to headphones
7 Select Japan ALPS high-end potentiometer.
8. Easy to install plug-in vacuum tube protective cover.

hey guys how's it going jay here welcome back to the channel so if you haven't already consider subscribing this is where we talk about hifi so if you have a passion for hi-fi like we do then consider subscribing now today we're talking about a little bit of a sensitive topic well i wouldn't call it too sensitive but we're talking about hi-fi products made in china okay so tri-fi we call it so a lot of people have been asking me why do you review so many chinese made stuff and first of all to answer that before i go too far into this video i'm not chinese i'm korean you have no idea how many times i review something and i understand i'm asian i'm of asian background but i've been living in north america since i was six years old and i've been living here practically all my life went through the education system here you know i quite frankly english is my first language so there's that b
