Classic EL34 Push-Pull Architecture
The Jazz 70’s output stage is built around four matched EL34 tubes in a Class AB1 push-pull configuration — a time-honoured design known for its harmonic richness, dynamic control and tonal refinement. Up front, three 12AU7 (ECC82) preamp tubes lay down a warm, detailed foundation, while the handcrafted toroidal transformer delivers clean, stable power with minimal interference. Expect an extended frequency response (8 Hz–60 kHz) and low distortion (< 0.2% at 1 W) that honours every nuance of your recordings.
Triode & Ultralinear Modes: Two Amps in One
Flip the mode switch and choose between 17 W (triode) and 35 W (ultralinear) per channel. Triode mode offers a smooth, intimate presentation with exceptional harmonic depth — perfect for late-night listening or acoustic sets. Switch to ultralinear for increased headroom and authoritative slam, ideal for rock, orchestral music and efficiency-challenging speakers.
Modern Connectivity Meets Classic Sound
Thanks to the Qualcomm QCC5125 chipset and ESS ES9018K2M DAC, Bluetooth 5.1 streaming reaches audiophile levels. Enjoy LDAC (up to 990 kbps), aptX HD, aptX LL for video sync, AAC and SBC. Whether streaming from your smartphone or tablet, the Jazz 70 ensures minimal compression artefacts and a wide operational range of up to 10 m.
Build Quality & Aesthetic Appeal
Available in sleek black or polished silver, the Jazz 70 sports a retro-inspired chassis complete with dual VU metres that double as bias monitors. The hand-wired, point-to-point construction eliminates PCB limitations, translating to a lower-noise signal path and enhanced long-term reliability. A removable tube cage protects your investment during transport.
