PSVANE AIR 12AU7 Double Triode Tube (Unit)
The PSVANE AIR 12AU7 power tube delivers a warm and smooth sound with ample, natural character and excellent balance alongside negligible background noise. PSVANE presents here a tube with a more pronounced analogue texture than conventional tubes, featuring vocals more forward than typical and an overall sonic character recalling the texture inherent to vinyl playback.
