Those who know Sansui with the famed later products, such as the BA-5000,
the CA-3000, or the AU-20000, or receivers and tuners, such as the G-33000
or TU-919, might say "Sansui Tube Gear???" However, the reality was
that Sansui built its foundation with transformer business, and established
its first international fame with the 1000A Tube Receiver. Of course,
the signature tube product was the AU-111 at the very end of tube era
followed by less known, but impressive tube amplifiers.
