【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
Standard model of authentic vacuum tube line amplifier
Adopts 6K4 as standard vacuum tube
Strengthened power supply stabilization circuit and improved S/N ratio
Equipped with a buffer circuit using an operational amplifier
AC adapter required (sold separately) DC12V/1A DC jack 5.5mm x 2.1mm (center positive)
Renewal to new lot from 12/11 2024 sales
・Changed the output coupling capacitor to TDK EPCOS MKT capacitor
The sound quality of vacuum tubes is enhanced by using a capacitor that produces high-resolution sound that is gentle and warm, without the harshness that can lead to listening fatigue.
・Other minor parts changes
There are no changes to the main board circuit this time.
vacuum tube line amplifier
FX-AUDIO-『TUBE-00J』
This product is a standard model of a full-fledged vacuum tube line amplifier newly designed with modern ideas.
Easy-to-handle 12V single power input (can be driven with a 12V AC adapter)
It is not a shoddy vacuum tube look audio, but a solid audio product with high sound quality inherited from the TUBE-01J, and new improvement points have been incorporated from the experience gained in the development of the TUBE-01J and TUBE-03J. It was completed by rationalizing the circuit.
We can confidently recommend this product in terms of cost performance in terms of sound quality and satisfaction level for the price!
If you don't have a vacuum tube line amplifier, check it out! Try opening a new door.
[How to use]
Please use this product by placing it between a power amplifier and a sound source playback device such as a CD player, DAC, or silicone player.
INPUT: Connect to the analog output terminal of a CD player, DAC, etc.
OUTPUT: Connect to the analog input terminal of power amplifier, main amplifier, etc.
*Please see the attached manual for detailed handling instructions.
[Note]
*AC adapter is sold separately. Please purchase the recommended AC adapter at the same time.
*This unit is a preamplifier. To connect to passive type speakers (not built-in amplifier), a separate power amplifier is required.
*There is no phono equalizer function. To connect to an analog player, you will need to connect it to a player with a built-in phono equalizer, or you will need a separate phono equalizer.
*There are high voltage parts inside, which may cause injury due to electric shock if you touch them. Also, never disassemble or modify the product as this may cause a fire.
