Sansui CA-3000

The Sansui CA-3000 was first sold in 1976 with a MSRP (Manufactuer's Suggested Retail Price) of $700.00. That's $2682.00 in 2010 dollars. It is part of Sansui's 'Definition' series that included the BA-3000 and CA-2000 power amplifiers as well as the TU-9900 tuner. The CA-3000 is somewhat unique in that it features two prominent level meters, a feature rarely seen on preamplifiers. The meters are calibrated in dB and will indicate input or output levels. It also features a highly user adjustable phono section with controls for pickup sensitivity, loading and capacitance. These settings are matched to the particular cartridge manufacturer's specifications to produce the most accurate frequency response for the phono system.

There are no known problem areas with the CA-3000 other than the usual age associated issues. The original "Sansui Bluie" meter lamps are no longer available, so suitable replacements must be fabricated.
