Vintage Pioneer SA-7500 & TX6500, Classic 1970's





Rare pair, Silver-faced 1970's vintage Pioneer integrated amp/tuner combo
The SA-7500 appeared in 1975 and was modestly rated at 40 watts per channel. It sold for around $300. This integrated amp was also sold in 1976 and 1977. It was a good seller for Pioneer having more contemporary look and reasonable pricetag. Legendary 1970's Japanese build quality & look. This great classic combo still have many years of service left. A punchie and bold performer, the SA-7500 sounds much bigger than it's power output (2 x 40 watt) might suggest.
The TX-6500 tuner is a solid performer and a perfect match for the SA-7500 circa 1977.
Both units are in near mint condition and recently serviced. Easy 9/10 condition both in function and cosmetically. Asking $210.00 for the pair. Pics are representative only. I can take some of my units if interested.

Details / Specifications:
Tuner: TX-6500 II
Superb Selectivity FM Front End
Junction type FET and frequency linear 3-gang variable capacitor are utilized in the front end to achieve an exceptional effective sensitivity.
Highly Stable FM IF Section
A high density IC, which incorporates 3 differential amplifier stages, plus diode limiter and quadrature detector circuits, is used together with two dual element phase linear ceramic filters int he IF amplifier section. By inserting a transistorized matching buffer amplifier between the ceramic filters, increased gain and phase response flatness are obtained, resulting in an outstanding effective sensitivity. Adjacent signal interference and even spurious signals at the same frequency as a desired station become strongly suppressed.
Multiplex Circuit Includes IC PLL
In order to obtain stable seperation without adverse effects from ambient temperature and aging variations, the stereo demodulator includes a newly developed IC Phase Locked Loop Circuit. Beautiful stereo reception can be enjoyed with superb harmonic and intermodulation distortion characteristics.
Advanced Performance AM Tuner
Selectivity and frequency response are improved by employing a high density IC and ceramic filter circuit in the AM tuner section.
Effective FM Muting
Small Sliding Station Reminders
Built-in AM Ferrite Bar Antennae
