PSVANE 6SN7 Replacement Tubes
CV181 / 6SN7 driver tube for balanced line stages and amplifier drivers
How to choose PSVANE 6SN7 / CV181 tubes
6SN7 and CV181 are octal dual-triode families used in compatible preamps, line stages, integrated amplifiers, and driver circuits. Shop this category when your amplifier manual specifies 6SN7, CV181, or a clearly compatible octal dual-triode position.
Choose AIR CV181-AT / 6SN7 when you need a current AIR-series option by tube quantity. Choose Treasure CV181-Z / 6SN7 when the amplifier benefits from a matched pair for left/right channel or balanced driver use.
Best fit
- Preamp, line-stage, and driver positions marked 6SN7 or CV181.
- Stereo circuits where a matched pair can improve channel balance.
- Buyers comparing AIR single-tube quantity options with Treasure matched-pair packaging.
Buying notes
- Confirm whether the amplifier accepts CV181 before replacing a position marked only as 6SN7.
- Use matched pairs when two tubes work as left/right channels or a balanced driver stage.
- Check heater current and maximum ratings before substituting related octal dual-triode labels.
CV181 and 6SN7 are often discussed together, but compatibility still depends on the amplifier circuit. Send the model if the manual is unclear.
