ACME 2A3 compatibility notes
- PSVANE ACME 2A3 is a premium ACME-series direct-heated triode for compatible 2A3 single-ended amplifiers.
- Choose it by the tube type named in the amplifier manual, not by socket shape or visual similarity.
- Do not interchange 2A3 and 300B unless the amplifier maker explicitly supports both tube families and operating points.
Before ordering ACME 2A3
- 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 2A3 output tubes. Confirm filament voltage, bias requirements, plate voltage, and matched-pair requirements before installation.
Sound Signature
Delicate, pure, and balanced, with expressive mids, comfortable long-session tone, and wide spatial layering.
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.
Shipping & Warranty
Warranty
90-day warranty against manufacturing defects. DOA coverage included.

What is the PSVANE ACME 2A3 used for?
The PSVANE ACME 2A3 is used as a premium direct-heated triode for compatible 2A3 single-ended amplifiers. It should be selected only when the equipment specifies that tube family or explicitly supports it.
Is PSVANE ACME 2A3 a drop-in replacement?
It is a replacement for compatible 2A3 positions. It is not a universal drop-in replacement for other tube families, even when the socket looks similar.
Should I buy ACME 2A3 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 2A3 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 2A3?
Check the amplifier manual, tube quantity, bias or power-supply requirements, and whether the circuit requires matching before installation.
