Sansui 7000

Sansui and Pioneer Freak
Hi all, here is another Sansui for my collection :)

I received this yesterday afternoon at work in the most beaten up box I had ever seen, and yet no damage done at all to the Sansui :banana: Must have been my lucky day!

The build quality of this is superb and its pretty heavy considering the size of it. I would closely relate this to the Seven and the Eight as it looks similar in design and look, and has the heatsink arrangment down the sides like the Eight. I'm gathering the 7000 was an in between model?:scratch2:

Someone has done a bodge/mod in the power supply- see photo. Will download the service manual for it also. It functions and sounds ok with this mod, but will investigate as to why it was put there in the first place.

Makes a nice change to have something old in workshop, I will take it home eventually and give it a good going over, also looks and sounds far better than all the modern hifi that I repair for a living!

Cheers!
Glen

The 7000 build quality is built like the Eight. The Sansui Appreciation web site has good comparsion of the single digit receivers. http://www.classicsansui.net/SingleDigitSeries.htm

My 7000 is like yours, all the dial lights are burn out. I just haven't had time to replace the fuse lights for the dial. Other wise it is a nice receiver like the Eight. Too many projects in the que.
 
My dial lights work in the 7000, they are just not bright, someone more than likely has replaced them with 12 volt lamps or the likes. Yes this line of Sansui receivers are really well built. I've got a Six as well, thats another nice unit.
Know what you mean about having too many projects in the que, I'm the same, and currently restoring an AU777A. :D

Cheers
Glen.
 
The 7000 shares a chassis with the Eight but has a very different amplifier circuit. It's power rating is a bit higher, 70 watt. I've never been able to figure out how it fit into the Sansui line. It was produced during the same time as the Eight and may predate the Eight by a couple of months. It must have been sold through different outlets because they are so close in apearance there wouldn't be much to differentiate them if they were both sitting on the same store shelf.

About the Dial Lamps, if my memory serves me correctly, many of these vintage 'Sui's used a 7v 250ma Lamp They are not always easy to find the exact replacements, but I have seen the correct ones recently.

I had found with a few sansuis I owned, that the typical 8v 250ma that places like Parts express sold did work, but a tad on the dim side. I had checked the voltage on a couple of these units, found that voltage was at around 5.9v-6.0v, and did get away using the 6v 250ma from parts express no prob.

Still, I'd prefer the correct 7v lamps if I could get them.
 
IIRC these receivers also only light the dial area when the receiver is set to tuner. I've always loved this classic receiver look.
 
I found out some more interesting facts about the 7000 in regards to its direct cousins.

The Six,Seven and Eight amplifier stages are all direct coupled and have protection on board, where as the the 7000 is capactior coupled and just has speaker fuses. Now it makes me wonder why they stuck with older technology on the 7000 when the output power is higher than the others?
Seems odd :scratch2: Oh well I guess Sansui had their reasons for doing this.

Also spied this on the side of the unit. See Photo. The sticker shows 'EP117V' This maybe a clue as to where this was sold originally.

Cheers
Glen.

Yes it is indeed :), but the EP may stand for something as all of my other Sansui's that have that sticker just have the voltage rating and nothing else.
Dunno, just a thought?:scratch2:

I believe that is 117 volts, a rating sticker.

I am fairly sure the the EP sticker indicates the unit was originally sold thru the Armed Forces stores system, of my collection I could trace a few of the units back to the place of purchase, those that I am sure about came from either the Navy Exchange of Air force stores always had that sticker.

I've heard that the 7000 was sold through the military exchange system but don't understand why they would make a specific model for that purpose. It is interesting to see that yours was originally a 117v model. I was hoping it would be 240v. That would show that they were sold in other markets. Did you find it in New Zealand?

Sansui Seven

The 7000 looks a lot like the Receiver Seven, except for the grey faceplate around the tuner. Any major differences? I'm new to the Sansui scene, so just picking for knowledge. I have seen the vintage Sansui sight and that has shed some light.
 
The Seven shares the basic chassis with the 7000, Eight and Eight Deluxe. The amplifier in the Seven is two generations newer than the 7000. The amp in the Seven is more closely related to the Eight Deluxe than either the Eight or the 7000. It's a great receiver.

It is also interesting to see a 7000 with a 220v sticker. That means at least some of them were destined for an export market other than North America. Still could have been sent to a US Military PX overseas though.

It has been a while, and my memory sucks, but I beleive the guy I got it from said his uncle got it while in the service, but I cant remember if he told me where...
 
I did find this one in good old NZ :) Whoever first owned it must have been in the military and would have bought it back with him into NZ at the time.

The 7000 has a higher output power than the Seven and the Eight. Its rated at 70 wpc into 8 ohms. It seems to be cross bred between those two.

Hi, this is my first post !

I used to work in a high end stereo store in late 70's (while in HighSchool). This was in Chile (South America). I clearly remember the G7000 being available in 1978... the voltage printed outside is sort of irrelevant since the transformer inside can take more than one voltage imput, ours were made for the American Market, so, some pre-sales prep was needed... open the case re-arrange couple of wires, or relocate a fuse and add the plug adapter at the tip. no more troubles!.

I invested few month of my salary to buy at cost a G7500, (-I loved it- It still in the family back in Chile... )

The G7500 was rated at ~90WRMS at 0.02%THD, The G7000 is one generation earlier, it should be at 85WRM with same THD? or may be 0.03 (the 70WRM is not in my memory)

Here in USA I just got a G7900z (and a set of SPX6900 :-)
