Description

ACME-series transmitting triode for compatible 845 amplifiers, selected for exceptional stability, high emission capacity, dynamic performance, and matched-pair service.

ACME 845 compatibility notes

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

Before ordering ACME 845

  • 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/845-vs-805.

Compatibility

Use only in amplifiers designed for 845 output tubes. High-voltage tube amplifiers require qualified handling and exact circuit compatibility.

Sound Signature

Powerful and nuanced, with treble extension, full-bodied midrange, and a realistic sense of scale.

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 845 used for?

The PSVANE ACME 845 is used as a premium high-voltage transmitting triode for compatible 845 SET and mono amplifiers. It should be selected only when the equipment specifies that tube family or explicitly supports it.

Is PSVANE ACME 845 a drop-in replacement?

It is a replacement for compatible 845 positions. It is not a universal drop-in replacement for other tube families, even when the socket looks similar.

Should I buy ACME 845 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 845 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 845?

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