Pioneer SA-9800

Integrated Stereo Amplifier (1976-81)

The Pioneer SA-9800 has the impressive feature which is the NSA (non switching amplifier), created specially by Pioneer.

This is a type of amplifier that adopts the merits of both class A and class B amplifiers, and it excels in keeping down the heat loss and allows the transistors to operate all the time in the active region.

For this reason, a high output power with a very low distortion factor is yielded all the way up to the high frequencies.
