PSVANE KT88 Replacement Tubes
Versatile tubes for push-pull designs
How to choose PSVANE KT88 tubes
KT88 is a beam power tube used in many push-pull hi-fi amplifiers and larger integrated tube amplifiers. Shop this category when your amplifier manual specifies KT88 or explicitly supports a KT88-family replacement path.
Choose ACME KT88 when you want the premium ACME-series KT88 option. Choose AIR KT88-AT or Treasure KT88-Z when those series better match budget, quantity, or system goals.
Best fit
- Push-pull output stages that specify KT88 power tubes.
- Amplifiers that need matched pairs or matched quads for balanced output behavior.
- Buyers comparing ACME KT88, AIR KT88-AT, and Treasure KT88-Z as different PSVANE series choices.
Buying notes
- Order a matched pair for two-output-tube amplifiers and a matched quad for four-output-tube amplifiers.
- Check the amplifier manual for bias requirements after replacing KT88 tubes.
- Do not substitute KT88 for EL34 or 6550 unless the amplifier maker confirms compatibility and bias range.
If you are replacing a non-KT88 tube label, send the amplifier model before checkout so the replacement path can be checked.
