Here’s another of the classic Pioneer receivers. The Pioneer SX-750 was an upper mid range receiver with a perfect complement of features and performance for someone wanting good performance while, at the same time, not breaking the bank. The SX-750 did just that while putting out 50 watts per channel at 0.1% total harmonic distortion. Manufactured during the heyday of silver faced receiver’s this particular model was introduced in 1976 and made through 1977. It had a retail price tag of around $400.
One interesting feature of the SX-750, and Pioneer SX-650 for that matter, is that the input/output terminals and circuits for the pre amp and tuner section are laid out on one large circuit board. According to Pioneer this allowed the use of unshielded input cables and also resulted in better overall tonal quality. Interestingly the performance of the SX-750 is not that far off from the flagship Pioneer SX-1250 with the exception of power output. So, not a bad value for $400 at the time.
The FM section utilizes a dual gate MOS type FET and a 4 gang variable capacitor for tuning. As you can also see the SX-750 has the standard styling of the time with silver faceplate, wood case and amber lighting.
Here are a few of its other features:
- Two tape in/outputs
- Duplicate switch
- Phono input
- Aux/mic inputs
- Tone and high filter switches
- FM muting
- Tuning and signal meters
- Two separate bass and treble controls
- Dimensions – 19 x 6 x 14.5
- Weight – 31.25 lbs
The back of the SX-750 is interesting as it has a protruding base on which the input and output connectors as well as the speaker outputs are located. The Pioneer SX-450, 550, and 650 also have this feature. It does make the units a little cumbersome to move.
The Pioneer SX-750 is a popular receiver given it is fairly reasonably priced and has the iconic name and look of a 1970’s silver faced receiver.
Here’s a video of a restored SX-750 you might find interesting. There’s actually a series of videos detailing this restoration as well.
