AIR KT88-AT replacement notes
- PSVANE AIR KT88-AT is a KT88 beam power tube for compatible push-pull hi-fi amplifiers and modern tube amplifier output stages.
- Use it where the amplifier manual calls for KT88 or an explicitly compatible KT88-family output tube.
- Do not treat KT88 as a casual replacement for EL34, 6550, or other output tube families unless the amplifier maker confirms the circuit supports that substitution.
Before ordering AIR KT88-AT
- Choose a matched pair for most two-tube push-pull output stages and a matched quad for four-output-tube amplifiers.
- Check whether your amplifier requires fixed-bias adjustment after replacing KT88 output tubes.
- Send the amplifier model before checkout if you are unsure whether you need single tubes, a matched pair, or a matched quad.
Compatibility
Use in KT88 positions in compatible amplifiers. Some amplifiers can also support related families such as 6550 or KT90, but substitution must follow the amplifier manual and bias range.
Sound Signature
Powerful and controlled with solid bass, saturated mids, and clean extension that works well in modern full-range systems.
Testing & Matching
Screened before shipment. Matched pairs and matched quads are recommended for push-pull output stages and channel balance.
Shipping & Warranty
Warranty
90-day warranty against manufacturing defects. DOA coverage included.

What does PSVANE AIR KT88-AT replace?
PSVANE AIR KT88-AT directly replaces KT88 positions in compatible amplifiers. Other output tube substitutions should be confirmed in the amplifier manual.
Is PSVANE AIR KT88-AT sold as a single tube or matched pair?
PSVANE AIR KT88-AT can be ordered as a single tube, matched pair, or matched quad depending on the amplifier output stage.
Does a KT88 need to be matched?
A KT88 should usually be bought as a matched pair or matched quad when it is used in a push-pull output stage.
Can KT88 replace EL34?
KT88 should not replace EL34 unless the amplifier manufacturer explicitly supports that change and the bias range is suitable.
Should I check bias before replacing KT88 tubes?
Yes. Many KT88 amplifiers require bias confirmation after output tube replacement, especially fixed-bias designs.
