THANK YOU FOR YOUR PATRONAGE ONTO LUXMAN $0505X

The SQSOSX is the newest transistorized pre-main amplifier
with full advantages yielded by the very circuitry the»
oretically regarded as the best one under exhaustive study
of LUX's engineering and designing.

Based on the styling of the renowned predessessor, the
30505, further refinement was applied in parallel with
improvement of the quality; The 80505X really deserves
the name of the decisive model in this output and price
bracket.

Main amplifier section integrates full stage direct coupling
circuit without output condensers by adoption of dual
power supply system in order to procure sufficient
damping factor and power character even to the extreme
low end frequency. The output stage with pure comple»
mentary system completely eliminates cross-over distortion.
The fore-stage adopts Zstage differential amplifiers which
ensure very stable performance eliminating the unplea
shock-noise at switching the mains powerl
Pre-amplifier section is equipped with
coupling circuit at equalizer stage.
