How to choose PSVANE 805 tubes

805 is a high-voltage transmitting triode used in compatible 805 amplifier designs. Shop this category only when your amplifier manual specifies 805 output tubes.

Choose ACME 805 when you need PSVANE ACME-series 805 tubes for a compatible amplifier. 805 designs require careful attention to tube quantity, bias, and high-voltage service safety.

Best fit

  • Single-ended or mono amplifiers designed for 805 output tubes.
  • Systems where the manual gives a clear 805 replacement and bias procedure.
  • Buyers who need a direct 805-family replacement rather than an 845, 211, 300B, or 2A3 substitute.

Buying notes

  • Confirm whether your amplifier needs one tube, a stereo matched pair, or another quantity.
  • Do not substitute 805 with 845, 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 805 replacements, send the amplifier model before checkout if there is any uncertainty about tube family, quantity, or bias.
