Pioneer SA-9800
(1978 - 1980)

Less features, less weight and a more conventional enclosure than the previous SA-9900 monster but a huge leap in specs, bandwidth and S/N ratios... And Fluorscan meters :-)


Magni-Wide Stereo Integrated Amplifier

"Pioneer's super-linear Ring Emitter Transistors (RETs), used for power output in the Magni-Wide amps in conjunction with a unique biasing circuit, solve the distortion and power problems. The Pioneer Vari-Bias circuit (PVB) causes the RETs to operate without switching or crossover, virtually as Class A power amps. Like the smooth automatic transmission of a car, it ensures a supersmooth "ride" for the electrons of the audio signal."
