Aurex SB-Lambda70C (1983) | Clean Drive

 

Aurex SB-Lambda70C (1983) | Clean Drive

Brand: Aurex/TOSHIBA
Model: SB-Lambda70C
Year: 1983

The SB-Lambda70C is using MOS-FET in the output stage and to further improve sound quality it is also using VX capacitors in the power supply section. It is also equipped with Aurex's unique clean drive. In the Clean Drive method, a distortion component detection code is added to the negative terminal side of the speaker. This detects the distortion component generated in the speaker and feeds it back into the amplifier. Then, the feedback amount is adjusted to cancel the distortion component in the amplifier. This eliminates the distortion caused by the transmission characteristics of the speaker cable and the back electromotive force generated in the speaker, and improves the dynamic characteristics.

Continuous power: 70W+70W (8ohm, 20Hz to 20kHz, both channel driven)
Total Harmonic Distortion: <0.007%
Frequency Response: 5Hz-100KHz 
Dimensions (WxHxD): 420x151x401 mm
Weight: 10,5 kg

PIONEER SA-9800 (1979) | Fluroscan Series

 

PIONEER SA-9800 (1979) | Fluroscan Series

Pioneer's Non-switching SA 9800 offers the efficiency found in the finest Class B amplifiers. With a distortion level found in the finest Class A. An unheard of 0.005% at 10-20.000 hertz. This level of performance is obtained by the use of RET (Ring Emitter Transistors) that greatly increase frequency response. Instead of slow-to-react VU meters that give you average readings the SA 9800 offers a Fluroscan metering system that is so fast and precise it instantaneously follows every peak in the power to make sure you're never bothered by overload or clipping distortion.

Continuous power: 2x100W 8ohm 10-20.000Hz
Total harmonic distortion: 0.005%
Frequency response: 5Hz-100kHz
Dimensions (WxHxD) 420x150x425mm
Weight: 18kg
