Mesa Boogie EL34 STR 446 Duet Amplifier Tubes
Rich British-style mids, harmonic layering, and a confident low-end foundation
The Mesa Boogie EL34 STR 446 Duet Amplifier Tubes are voiced for the harmonic complexity and authoritative midrange associated with classic EL34 power sections. Compared with leaner vintage interpretations, the STR 446 adds extra body through the middle frequencies and a fuller, richer low end.
Features
Built as a premium-grade power pentode, the STR 446 is screened for reliable operation in demanding high-voltage amplifier circuits. Its 25-watt plate-dissipation rating, strong upper-harmonic reach, and quick, tight attack make the duet a natural fit for rock, hard rock, and modern high-gain tones in amplifiers designed or approved for EL34 operation.
