Sansui G-4700

 

This Sansui G-4700 is from their line of Pure Power DC receivers from the late 1970's. It was at the bottom of their G-X700 line but still produced a respectable 50 watts per channel. Sansui had other budget oriented receivers at the time such as the G-301 and G-401 so the G-4700 was really in the middle of their performance lineup. It retailed for about $430.

The G-X700 line all featured a symmetrical layout with two big knobs a the center bottom of the face plate that control volume and tuning. It also has push buttons for FM Mode, Subsonic Filter, Loudness and Tape Monitor

The Sansui G-4700 looks alright when it's powered off but hit the power switch and dim the lights and you're in for a treat. It is one of the better looking receivers from the late 1970's when lit up. Interestingly it has both digital and analog tuning displays. FM tuning is digitally quartz locked to prevent drift. The left and right peak power meters are also digital.

Inside, the G-4700 is laid out well. The design features Sansui's exclusive DC technology in the power amplifier section. Phase distortion and other related amp problems are eliminated due to the fact that Sansui uses no capacitors in the amplifier circuit. The sound that goes into the amp circuit comes back out nice and clean and distortion free.

If you're thinking of buying a G-4700 there are a couple things you should keep in mind. First, they don't particularly like to power speakers at less than 8 ohms or even two pair of 8 ohm speakers for that matter. There is a particular transistor that tends to heat rapidly when the receiver is under too heavy a load. Of course, many receivers will overheat if worked too hard so it's not just a Sansui problem. Second, the digital display can fail. It is controlled with either one or two IC chips and they aren't really replaceable without a donor parts unit. So, if the digital display is dead on the unit you're considering you may want to pass.

Overall, the Sansui G-4700 is a great sounding receiver with it's tuning section being its strongest feature. Many G-4700 owners rave about the clean pure sound of this receiver. At 55 WPC it produces plenty of power for a moderately sized room and it has all the features you'll most likely need.

Vintage Sansui receivers are highly sought after but fortunately quite a few were manufactured as well so most aren't considered rare. A really nice G-4700 can be purchased for around $200 with average condition units costing half that. If you're looking for a mid range receiver with higher end performance then the G-4700 is certainly worth considering.

Sansui 1000x

 

This great little entry level receiver is the Sansui 1000x. Introduced in 1970 it is a well built and great looking receiver. Here's what Sansui had to say about it:

With an unprecedented 100 watts power, the latest FET components, functional front panel design and an ability to handle two speaker systems, the 1000X considerably advances the art of stereophonic reproduction.

It puts out 28 watts per channel into 8 ohms and 35 into 4 ohms.  It has a great FM tuner overall excellent build quality and is very simple to operate.

Aesthetically it is a great looking receiver. It has a nice well built wood case, black dial face with green back lighting and nice front panel layout. The toggle switches are crisp and well sized. Another interesting feature is that the bass and treble can be controlled for each channel independently. The inner part of the control knob adjusts the left channel and the outer part the right.

The Sansui 1000x is totally capacitor coupled and uses all NPN transistors and a single rail power supply. A completely discrete amplifier and pre-amp circuits give the receiver a great sound stage. It weighs in at just under 23 pounds and measures 16.4 x 5.7 x 11.8 inches.

As I mentioned above the Sansui 1000x is a fantastic entry level receiver with plenty of power for most applications. Both its looks and its performance make it very popular. A good functioning unit can be found for $125 to $200 depending upon condition.
