FX-AUDIO- TUBE-00J black Full-scale vacuum tube line amplifier from Japan new

Vacuum tube line amplifier
FX-AUDIO-"TUBE-00J"
This product is a standard model of a full-scale vacuum tube line amplifier newly designed with a modern idea.
Easy-to-use 12V single power input (can be driven by a 12V AC adapter)
The high-quality finish is inherited from TUBE-01J as a solid audio product, not a fake vacuum tube look audio, and new improvement points are reflected from the experience gained in the development of TUBE-01J and TUBE-03J. It was completed by rationalizing the circuit.
We can confidently recommend cost performance such as sound quality and satisfaction with respect to the price!
If you don't have a tube line amp, come on! Try opening a new door. [How to use]
Please use this product by inserting it between a power amplifier and a sound source playback device such as a CD player, DAC, or silicon player.
INPUT: Connects to an analog output terminal such as a CD player or DAC.
OUTPUT: Connect to the analog input terminal of a power amplifier, main amplifier, etc.
* Please see the attached manual for detailed handling instructions. Product features
・ Adopts 6K4 as a standard attached vacuum tube
The TUBE-01J used a 6J1 military tube for the attached vacuum tube, but since the 6J1 is already difficult to obtain, the standard model TUBE-00J has adopted the 6K4 as standard.
The design itself is based on 6J1 and has been adjusted so that there is no problem with 6K4, but in order to experience the original ability, a set of 2 replacement vacuum tubes mil-spec (military grade) and replacement vacuum tube 2 Individual set We recommend mil-spec sorting grade products (both sold separately).
It's not that 6K4 isn't good, it's the difference in taste, so it's one of the pleasures of TUBE-00J to find your favorite vacuum tube.
・ Strengthen the power supply stabilization circuit
The noise filtering circuit has been changed from physical input to pinpoint.
The power supply stabilization circuit in the product has been fundamentally reviewed from the concept, and the circuit design aims at noiseless supply with a booster IC and a power supply circuit with good reaction speed.
・ Improvement of SN ratio
While maintaining the stability of the ground along with the increase in the voltage of the power supply circuit, the isolation due to the potential difference to a specific frequency is further strengthened.
The improvement of SNR and the reduction of total harmonic distortion are realized by stabilizing the operation of the vacuum tube itself.
・ Equipped with a buffer circuit using an operational amplifier
The buffer circuit uses the Texas Instruments audio operational amplifier "NE5532" (DIP socket type), which has high cost performance in terms of sound quality!
The power supply of the operational amplifier is equipped with a dedicated power supply filter, and draws out the full power of the operational amplifier.
In addition, a metallized film capacitor manufactured by PILKOR is used for the output coupling from the operational amplifier. Even in the standard model, the important part is suppressed.
・ Output coupling with a margin even at maximum output
For the output coupling, a high-voltage film capacitor made by BC Components (formerly Philips) made in Belgium and custom-made is used. FX-AUDIO-A proven gem that is often used in products.
・ I am confident in the sound quality even with the standard model!
We are trying to improve the overall circuit and reduce the number of passive parts to improve efficiency, but since each circuit has improved performance, it is a vacuum tube line amplifier with extremely high potential when viewed in total. increase. [Recommended power supply]
Recommended AC adapter:



[Maintenance / optional parts]










【please note】
* AC adapter is sold separately. Please purchase the recommended AC adapter at the same time.
* This unit is a preamplifier. A separate power amplifier is required to connect to passive type speakers (not built-in amplifier).
* There is no phono equalizer function. To connect to an analog player, connect to a player with a built-in phono equalizer, or a separate phono equalizer is required.
* There is a high voltage part inside, and if you touch it, you may be injured by electric shock. Also, do not disassemble or modify it as it may cause a fire. 【spec】
