Description

ACME-series direct-heated triode with globe glass, gold-plated grid construction, carefully screened parameters, and at least 24 hours of factory burn-in for high-end 300B amplifier use.

ACME 300B compatibility notes

  • PSVANE ACME 300B is a premium ACME-series direct-heated triode for compatible 300B SET and push-pull amplifiers.
  • Choose it by the tube type named in the amplifier manual, not by socket shape or visual similarity.
  • Do not substitute 300B with 2A3, 845, 805, or 211 unless the amplifier maker explicitly supports that tube family.

Before ordering ACME 300B

  • Confirm the exact amplifier model, quantity, and whether the output or rectifier position needs a matched pair or larger matched set.
  • High-voltage power and rectifier tubes should be installed only after checking the amplifier manual and bias or power-supply requirements.
  • For broader ACME-series context, compare this product with the ACME collection and the related guide at /guides/300b-vs-2a3.

Compatibility

Use only in amplifiers designed for 300B output tubes. Confirm filament supply, bias method, plate voltage, and matched-pair requirements before installation.

Sound Signature

Warm, emotionally engaging, and natural, with strong vocal presence, broad staging, and smooth detail retrieval.

Testing & Matching

Official PSVANE ACME listings describe careful parameter screening, at least 24 hours of factory burn-in, matched-pair service where selected, and 12-month warranty coverage.

Buying questions

What is the PSVANE ACME 300B used for?

The PSVANE ACME 300B is used as a premium direct-heated triode for compatible 300B SET and push-pull amplifiers. It should be selected only when the equipment specifies that tube family or explicitly supports it.

Is PSVANE ACME 300B a drop-in replacement?

It is a replacement for compatible 300B positions. It is not a universal drop-in replacement for other tube families, even when the socket looks similar.

Should I buy ACME 300B as a matched pair?

Matched pairs are recommended when two tubes serve left and right channels or paired output positions. Confirm the amplifier quantity before ordering.

How does ACME 300B compare with AIR or Treasure series?

ACME is positioned as PSVANE premium ACME-series construction, while AIR and Treasure are separate PSVANE series choices. The best option depends on amplifier compatibility, budget, and the tube family required.

What should I check before installing ACME 300B?

Check the amplifier manual, tube quantity, bias or power-supply requirements, and whether the circuit requires matching before installation.
