AIR 845-AT replacement notes
- PSVANE AIR 845-AT is an 845 high-voltage transmitting triode for compatible 845 SET and mono amplifier designs.
- Use it only where the amplifier manual specifies 845 tubes and gives the correct installation and bias procedure.
- 845 tubes are not interchangeable with 300B, 2A3, 805, or other direct-heated triodes unless the amplifier is designed for that tube.
Before ordering AIR 845-AT
- Confirm whether your amplifier needs a single 845 tube, a stereo matched pair, or another quantity.
- Because 845 amplifiers run high voltage, follow the manual and use a qualified technician when bias or internal access is required.
- Send the amplifier model before ordering if you are replacing an 805, 211, 300B, or another nearby triode label.
Compatibility
Use only in amplifiers designed for 845 output tubes. 845 amplifiers operate at high voltage, so installation, bias checks, and service should follow the amplifier manual or a qualified technician.
Sound Signature
Large-scale and authoritative with strong low-end foundation, open upper range, and a broad soundstage for demanding speaker systems.
Testing & Matching
Checked before shipment and packed with extra protection for large glass output tubes. Matched pairs are recommended for stereo and monoblock amplifier sets.
Shipping & Warranty

90-day warranty against manufacturing defects. DOA coverage included.
