Description
The PSVANE AIR 12AU7-AT / ECC82 is a medium-gain dual-triode tube for line-stage, buffer, DAC output, headphone amplifier, and driver positions. It is chosen when the circuit needs stable tone, good control, and lower gain than a 12AX7-family tube.
AIR 12AU7-AT / ECC82 replacement notes
- PSVANE AIR 12AU7-AT / ECC82 is a medium-gain dual-triode tube for compatible line-stage, DAC output, headphone amplifier, and driver positions.
- Use it where the equipment manual specifies ECC82, 12AU7, or a supported 12AU7-family tube.
- This is a strong fit when the system needs a lower-gain line-stage or driver tube rather than an ECC83 / 12AX7-family gain tube.
- ECC82 / 12AU7 is not a gain-equivalent substitute for ECC83 / 12AX7 or ECC81 / 12AT7 unless the circuit supports that change.
Before ordering AIR 12AU7-AT / ECC82
- Choose matched pairs when the tubes serve left and right stereo channels.
- Ask for matching help when the two tubes serve a balanced line stage, stereo preamp, or paired driver position.
- Confirm whether the equipment uses one 12AU7 tube, a pair, or several tubes in different positions.
- Send the model before checkout if the current tube label is 5814, CV4003, or another related 12AU7-family name.
Compatibility
Use in ECC82 / 12AU7 / 5814 / CV4003 positions when the amplifier or source component supports that family. Do not substitute with ECC83 or ECC81 families unless the manufacturer explicitly allows it.
Sound Signature
