PSVANE 845 Replacement Tubes

High-power tubes for demanding systems

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 ACME 845 for the premium ACME-series 845 option, or AIR 845-AT when you want the AIR-series path. 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.
