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.

The TX-6700 was offered by Pioneer between 1978 and 1980. It did not have the family resemblance of other tuners in the Pioneer line in the late 1970s. The reason for this is the location of the signal strength and stereo signal meters on the front panel instead of the tuning dial area. The original price was $180.00
