How to choose PSVANE 845 tubes

845 is a high-voltage transmitting triode used in compatible 845 single-ended and mono amplifier designs. Shop this category only when your amplifier manual specifies 845 output tubes.

Choose PSVANE AIR 845-AT for compatible 845 amplifiers that need an AIR-series replacement tube. Because 845 designs run high voltage, safety and the exact amplifier model matter before ordering.

Best fit

  • Single-ended or mono amplifiers designed for 845 output tubes.
  • Systems where the manual gives a clear 845 replacement and bias procedure.
  • Buyers who need a direct 845-family replacement rather than a different triode family.

Buying notes

  • Confirm whether your amplifier needs one tube, a stereo matched pair, or another quantity.
  • Do not substitute 845 with 805, 211, 300B, or 2A3 unless the amplifier maker explicitly supports it.
  • Use qualified service help when the amplifier requires high-voltage bias checks or internal adjustment.

For 845 replacements, send the amplifier model before checkout if there is any uncertainty about tube family, quantity, or bias.
