Sansui 7000

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 :-)

Welcome to AudioKarma exclusively Sansui Forum. You will find we have a world wide audience here and are always interested to hear first hand experience with Sansui.

The model being discussed in this thread is the 7000. It predates the G-7000 by 6 or 8 years. It is a very different receiver.

Glen, The 7000, the Eight and the Seven share basically the same chassis but have very different amplifier designs. The Seven is much more modern with NPN/PNP output pairs and a relay based protection circuit. The 7000 and the Eight have two different designs of cap-coupled amps.

Hello,
I have a sansui 7000 that has been collecting dust for some time. It has no audio and the power transisters are out. I looked at the number on the transisters but it does not agree with the manual that I have. I am not looking at the manual now but do you know the ariginal numbers of the transisters and the brand.
Thanks
Jesse
 
I picked up a 7000 at a garage sale - she wanted $5 - I gave her $3 - took it to my local repair shop - plugged it in - EVERYTHING works - needs cleaned up but hey!!

The original output transistors are 2SC1116. They are long out of production. Replace them with OnSemi MJ21194G. Before you do, check the driver board to be sure there are no faults. The original transistors were pulled for a reason.

I do also own two 7000, one has its complete original box and papers.
I also have, in addition to dozens of other receivers belonging to this era, Sansui Eight, Seven and Six.

But a few of them lack some aluminium plates with the writing on it. The plates of the black push buttoms.

Does anybody have an idea where to get these plate from? All companies I asked for making these haven't been able to produce such small writing on the plates.
 
send a pm to BrandXRC - ( a few posts above) he may be able to hook you up. How does the 7000 sound compared to your other ones - the eight, seven, etc? I have one and it has good power, but sounds flabby/tuby in the bass and overall kinda of dull. wonder if that is they way they sounded back then or needs a recap. cosmetically its in very good condition.
 
Thanks for the hint...

Comparing the 7000 with its brothers/sisters, I do not hear any major differences - except the more powerful performance of the 7000. And I didn't change anything inside. No recapping. Sometimes it is very helpful to clean all switches and potentiometers - the sliders. The dirt could cause an unharmonic sound. In most of all cases, recapping is not necessary. The old capacitors have enough power - even if they are 40 years old or more. Dried or flown out caps are very seldom...
 
If it's working properly, a 40 year old receiver will sound fine with it's original caps. But it will not sound as good as it did when it was new. If you really want to experience the original Sansui sound, change out all the electrolytic caps. It will give you a more detailed richer sound.

I've always subscribed to the old adage, if it ain't broke, don't fix it. So I had a hard time believing that changing the caps would make a difference in a good working receiver. Then So Cal Sam and I did an A-B comparison with an original unmolested Eight and one that I had recapped. We used the same audio source and speakers. The difference was obvious. It made a believer out of both of us.

So is it necessary to replace the 40 year old caps? Only if you want to hear the true potential of this wonderful old equipment.

Very nice. Good pictures too.

The ID plate on the back only lists a single input voltage, 220v. I've never seen a single voltage model from that era. It is also missing the electrical outlets from the back panel so it is truly a European market model. The "power limiter" is a feature I hadn't noticed before either.

Regarding the build date of the 7000.....I think it's most likely the earliest these units date from is 1969 or 1970.... I might have even seen some reference to the 7000 in a late 60's magazine....I can't recall which?

FROM the Serial No. on the excellent back photo on the unit above we can tell when the unit was made....
First two digits = the Assembly Line Factory number. (22) 22
3rd digit = The year it was made (1)....so 1971
4th and 5th digits refer to the month (09) ...so September
Last four digits = how many units built (0118) ...so the one above is the 118th one built.

From what I can ascertain, the 7000 appears to be the top model in the older late 60's/early 70's - 800/1000/2000/4000/5000 range. But below the larger, button crazy (but lower powered) 3300 & 5500 stereo units (..the earliest of which date to '69). When the range was updated, the 7000 body style was carried over to the new Model 6/7/8 range whereas the new Quadraphonic 5500/7500 units styling morphed from the 3300/5500 stereo units (..they look very similar.!!). The older Quad units i.e. QR3500/4500/6500 are styling orphans among all this.

That's as much as I've been able to piece together from the fragments I read about these units over the years.

The 7000 is an enigma. It was made concurrently with the Eight and the 5000X. It uses the chassis and styling of the Eight but it's amp design is closer to the 5000.

The database has recorded these production ranges:

7000 from 3/71 to 9/71. (16 units recorded)
Eight run from 12/70 to 6/72 (16 units recorded)
Eight Deluxe 6/73 to 5/74 (11 units recorded)
5000X - 2/71 to 8/72
5000A - 9/69 to 9/70
5000 - 7/68 to 12/69 (12 units recorded)

The serial number of the unit pictured above is not recorded in the database. If anyone has examples of these receivers, please post the serial numbers in the database thread.

Wow....so the 7000 and the Eight were actually sold side by side and from the info you've got, your earliest recorded Eight actually pre-dates the earliest 7000 recorded even though the Eight's are technically (as is my understanding) a more advanced design.

Cheers....thanks for the info Pete.

........I just found your database thread...........very handy........

Good to see one of my old posts up again! :) I'm no sure if I did put my 7000 in the database? Seem to recall it was built in 1971 though.

Hi Pete, have just added it to the database, it reads 222110328 so my 7000 must have been a late one was made in Nov of 1972 number 328 off the production line it seems...:)

Glen.

Your serial number is not listed in the database, at least as of this morning.

Thanks Glenn. I sure wish I could have made it over to Wellington when I was in NZ last year. I would have liked to see your "wall of sound."

Hi Pete, what a shame, would have been great to have met you :) Well if you're ever over here again in NZ and happen to be in Wellington, you are more than welcome to come and visit, we'll make sure the kettle is on! :yes:

Cheers
G.
