Why ‘Overhung Filament’? 

Overhung filament is physically isolated from the tube structure and reduce unwanted external vibration to the tube itself. It will create a quieter background for the tube sonics by design.

To implement overhung filament design in tube production, it requests tight quality control and demand high production costs.

Unique graphite plate:

The large graphite plate has 3 side holes for heat dissipation and at the same time to let tube glow to be seen. If you are a fan of  tube glowing, this is a great looking tube while enjoying your tunes!
