A booklet for the SANSUI AU-F EXTRA lineup - three integrated DC amplifiers and a tuner under the shared “EXTRA VERSION” branding. The whole series is built around the Super FF circuit: direct-coupled stages without electrolytic capacitors, with a Diamond Differential input. The flagship AU-D907F EXTRA gets a full spread to itself - detailed circuit diagrams, internal photos and measurement graphs. AU-D707F EXTRA and AU-D607F EXTRA follow. The TU-S607 EXTRA is a quartz PLL synthesizer tuner, marketed as tuned to “disc-level sound”. The final spread shows silver-panel variants of the whole lineup plus the GX-A1 rack.
- スーパーFF回路 - Super FF (Full Flat) circuit - DC-coupled design with extended bandwidth
- ダイヤモンド差動回路 - Diamond Differential - differential input stage with transistors in diamond configuration
- DCアンプ - DC amplifier - direct-coupled, no electrolytic capacitors in signal path
