Kuuleyn Vacuum Electron Tube Valve Preamp Amplifier Board Headphone Amp Parts Musical Fidelity Kit, 6J1 Audio Tube Headphone Amplifier, Compact Electronic DIY Kit DIY Parts (Static Bag)

【Funtion】Connect the 6J1 tube pre-amp between sound source and amplifier, it will effectively filter digital flavor, the music and human voice will be relatively good.
【Eight 470uf Capacitor Filter】Eight 470UF capacitor filter is very clean, excellent power system to no hum, filaments are powered with DC 12V and need to be connected in series in order to reduce noise.
【High Frequency And Low Proof】A coupling capacitor is an electrodeless electrolytic capacitor with high frequency and low proof.
【Easy To Use】Using DC 5.5*2.1 socket and AC 12V transformer, you can also use AC 12V transformer without a plug, just need to weld the power cord onto the circuit board.
【Can Yourself Assemble Them】This kit comes in parts so you can assemble them together by yourself, enjoy the process of building your own tube amplifier.

【Heavy-duty】Professional and multi-purpose direct injection box for stage and studio applications.
【High sound quality】Provides impedance and signal matching for the direct connection of instruments to mixers and amplifiers.
【Clean and pure 】Ultra-flat frequency response due to renowned Donner LAB-S1 transformer .The transformer also helps eliminate hum and buzz caused by ground loops by isolating the input from the output..
【Robust circuit design】Converts a line or instrument level unbalanced signal to a low impedance mic level balanced signal.
【Low noise】Ground Lift switch eliminates typical ground loop problems .Send the thru signal to your amp and the output to the PA system. Transformer isolation eliminates nasty hum and buzz caused by ground loops..

380 mm (15 in) woofer with Kevlar-reinforced Cone and 75 mm (3 in) voice Coil, 38 mm (1. 5 in) diaphragm Compression driver with patented design and high temperature polymer diaphragm..
Extraordinary clarity for speech, with extended frequency response for music, advanced high-slope crossover network for constant coverage and smooth, natural midrange..
500 watt power handling (average continuous Pink noise) with high sensitivity provides high SPL capability..
300 watt 70V/100V multi-tap (built-in transformer) or direct 8ω low-impedance, 52 Hz – 20 kHz frequency response..

The single-band 80m-10m end-feed half-wave linear antenna provides the antenna. It is designed as a highly portable wired antenna that can be easily set as an inverted V-shaped, horizontal, tilted, or vertical radiator (at higher frequencies)..
Your feeder is inherently balanced, so no separate feeder is required. The high-impedance half-wave line is matched to your 50-ohm feed point through an integrated impedance-matching toroidal transformer with a rated power of 10 watts..
Use a high-voltage capacitor on the primary of the transformer with a specific radiator length to further expand and reduce the SWR within the range of 80m-10m..
It is designed to be used without the use of a tuner, and after optimizing the driven element, SWR ≤ 1.2 for any part of the frequency band..
Package Included: 1 x Portable No Tune End Fed Half Wave Antenna.

SUPERIOR SOUND. High-current EI transformer makes sure that sound quality doesn't suffer. Large custom audio capacitors and a discrete output stage..
AMP TECHNOLOGY. Wide Range Amplification Technology delivers high-current power stability via large custom capacitors, while low-NFB amps capture depth and spatiality for a wide frequency spectrum with low distortion..
AUTHENTIC AUDIO. Direct Mode bypasses tone and PM Bass circuitries. In combination with a refined amp circuit design, signal-pathlengths have been significantly reduced in comparison to the A-9010 for even more accurate and faithful sound..
BASS BOOST. Phase Matching Bass Boost eliminates phase-shift between low- and mid-range frequency bands. Bass response is enhanced without compromising vocal clarity, which is especially useful when playing music at low volumes..
FEATURES. 50 W + 50 W (4 ohms, 20 hz–20 kHz, 0.9% THD, 2-ch Driven, FTC). Remote controller..
