Pioneer SA-6500 Integrated Amplifier and TX-6500 tuner (1977-1978)
The SA-6500 was one of Pioneer's mid-range integrated amps in the mid-1970s. The SA-6500 was rated at 25 watts per channel. Interestingly, this amp had the same low intermodulation distortion and total harmonic distortion specs as the top-of-the-line SPEC-2 amplifier, 0.1 %. So, while the buyer of this amp couldn't afford a SPEC-2, he could boast it had the same specs!
The TX-6500 II tuner was also introduced in 1977 and was a step up from the TX-5500 II in terms of features and performance. It featured better stereo separation and signal to noise ratio, and the extra circuitry components resulted in a weight of 12.50 pounds. It had a list price of $200.00. This tuner was a good seller for Pioneer and it was offered again for 1978.
