Sansui BA-3000 (1975) - The Definition Series

Uncompromising. When a musical performance must be reproduced to the most critical standards, The Definition Series from Sansui can deliver flawlessly the entire audio spectrum. The Sansui BA-3000 has all the design features of the Definition Series, with a power output of 170 watts per channel, minimum RMS, both channels driven into 8 ohms over a 20 to 20,000Hz bandwidth, with no more than 0,05 % total harmonic distortion; 340 watts, minimum RMS in mono. Features include: Four jumbo heat sinks coupled directly to the power transistors eliminate the need for a cooling fan. LED Power/Protector indicator on front panel glows red when power is switched on, turns green to indicate safe operation; turns red to warn of potentially harmful conditions. BA-3000 has all the safety features, subsonic filters and distortion-free toroidal coil winding power transformer. The Sansui CA-3000 is a stereo control preamplifier featuring advanced space-age design in every link of the circuit chain, for unprecedented accuracy. It has RIAA ± 0.2dB Equalization which is capable of meeting all the strenuous demands of contemporary disc recordings which feature extremely wide dynamic range. The CA-3000 handles an extremely wide frequency response covering all musical signals with low distortion, no clipping or noise. Features include: High input impedance and low output impedance, through newly-developed unit amplifier circuits: a differential amplifier at input, and an emitter-follower or SEPP buffer amplifier at output. Phono equalizer features a packed differential dual FET amplifier (with a matched pair of low-noise FET's) at the initial stage, and Class-A complementary SEPP amp at output. Full controls and connections for any combination you're likely to need.
