Second and fourth harmonics add richness without altering source character. Measured at 0.8% THD at rated output — transparent enough for purists, alive enough for listeners.
Direct-heated 300B topology delivers voltage amplification with no push-pull artifacts. Zero global feedback — the signal path stays honest from input to output.
Every connection soldered by hand on turret boards — no printed circuit traces to introduce capacitance. Signal travels through air, not fiberglass.
Tubes compress transients naturally as they approach saturation — no hard digital ceiling. The louder you push, the more the amplifier gently rounds the peaks.
