Authentic Vacuum Tube Line Amplifier FX-AUDIO- TUBE-00J (black)

---------------------------------------------------------------------- 【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer.

【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 sale ・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.
