PSVANE ACME vs AIR vs Treasure: Which Series Should You Choose?
PSVANE ACME, AIR, and Treasure are different series choices within the PSVANE tube catalog. The right choice starts with the tube family your amplifier requires, then moves to series positioning, matching needs, and budget.
If the manual specifies a tube family, choose within that family first. A PSVANE ACME 300B is not a replacement for 2A3, 845, or 805 positions. A PSVANE ACME 274B rectifier tube should only be used where the amplifier or power supply supports 274B-family rectifiers.
Quick Series Comparison
| Series | Best for | Typical buyer question |
|---|---|---|
| ACME | Premium PSVANE ACME-series tubes for compatible high-end amplifier positions | "I want the ACME option for my exact tube family." |
| AIR | Current PSVANE options across common small-signal and output families | "I want a modern PSVANE replacement with clear compatibility notes." |
| Treasure | Matched-pair oriented classic PSVANE positioning for selected families | "I want the Treasure-series pair for my compatible amplifier." |
When ACME Makes Sense
Choose ACME when your amplifier clearly specifies the same tube family and you want the ACME-series option:
- PSVANE ACME 300B for compatible 300B amplifiers
- PSVANE ACME 2A3 for compatible 2A3 amplifiers
- PSVANE ACME 845, ACME 805, or ACME 211 for compatible high-voltage transmitting-triode amplifiers
- PSVANE ACME KT88 for compatible KT88 output stages
- PSVANE ACME 274B for compatible 274B rectifier positions
The full ACME lineup is also grouped on the PSVANE ACME Series collection.
When AIR Makes Sense
AIR is useful when you need current PSVANE options in common replacement categories, especially small-signal and output tube families. Examples include AIR 12AX7-AT / ECC83, AIR 12AU7-AT / ECC82, AIR 845-AT, and AIR KT88-AT.
AIR can be the more practical choice when the amplifier uses a common family and you are prioritizing availability, quantity flexibility, or a direct modern PSVANE replacement.
When Treasure Makes Sense
Treasure-series listings are often useful when you want a matched pair in a supported family, such as Treasure 300B-Z, Treasure 2A3-Z, Treasure 274B-Z, or Treasure KT88-Z.
Treasure can be a strong path when the amplifier quantity matches the listing and you want the Treasure-series presentation instead of ACME or AIR.
Compatibility Comes First
Before choosing between ACME, AIR, and Treasure, check:
- The exact tube family printed in the amplifier manual.
- The number of tubes required per channel or per amplifier.
- Whether the position needs a matched pair, matched quad, or single tube.
- Bias requirements for output tubes such as KT88, 300B, 2A3, 845, 805, and 211.
- Rectifier power-supply limits for 274B replacements, including filament current, rectified current, and filter design.

Short Answer
Choose ACME when you want PSVANE's ACME-series option for the exact tube family your amplifier supports. Choose AIR when you want a current PSVANE replacement path with practical availability. Choose Treasure when the matched-pair Treasure listing fits your amplifier and sonic goals.
