PSVANE ACME Series
PSVANE ACME Series vacuum tubes for high-end audio amplifiers
The ACME lineup covers premium direct-heated triodes, transmitting triodes, a KT88 beam power tube, and a 274B rectifier. Choose by the exact tube family specified by the amplifier manual: ACME 300B, 2A3, 845, 805, 211, KT88, or 274B.
ACME pages are written for compatibility-first buying: tube family, amplifier quantity, matching, bias, filament supply, and rectifier power-supply limits matter before checkout.

ACME 300B and 2A3
Use ACME 300B or ACME 2A3 only when the amplifier specifies that direct-heated triode family. These families are not casual substitutes for each other.
ACME 845, 805, and 211
High-voltage transmitting-triode amplifiers require exact tube-family compatibility, correct bias, ventilation, and qualified handling.
ACME KT88 and 274B
KT88 replacements depend on output-stage bias and matching. 274B rectifier swaps depend on filament current, rectified current, and filter design.
