I’m a bit late to the party here but I have a “garage find” Sansui G-9000. You mentioned that the two pieces in front of the dual capacitors had the right side with a lid and the left side without. Mine has the same configuration. BTW, I got the receiver, a pair of Cerwin-Vega hed U-351 speakers and a pair of Cerwin-Vega 300SE speakers for US $250.00!!
As big and beautiful as the G-9000 clearly is! I own one. There's two bigger by Sansui. Their G-22000 and the G-33000!! Each unit are of a two piece configuration!
Excellent video.. you are obviously highly proficient with your work. I have the Sansui G-8000 from 1979, and it looks identical to this one, with a few less features.

It is just too beautiful and well crafted to part with, and I'm sure it needs the repair and overhaul like you did here.. At least now I am optimistic that there is still hope for this wonderful piece of equipment.. Thank you, from Florida.
I bought my G9000 DB at the Pony LTD in Fussa City Tokyo Japan in 1978 brand new for $450.00 Left channel has a short in the balance knob but its still a audiophile piece of beauty I love this receiver even in 2020 💪🏿👌🏾😎✅😃🎶🎶🎶
I found one of these in the trash 2 days ago and brought it home not knowing what it really was. So far it turns on but haven't hooked up any speakers yet. I am going to restore it and learn about it
Wow, quite a find! Lots of amazing equipment like this ends up in the trash because technicians lack the ability to repair it and owners don't want to spend the money to have it properly repaired. Tragic really, because most faults with these and other vintage amplifiers and receivers are very fixable.

Hello, how are you? I need the output transistors and the Sansuo G5700 icitators. Would you have it for sale or would you know of any contacts? Here in Brazil I can't find them. I also need those two plates that come out of the price plate, and go to the dicipator, where the output transistors go. If you can please help me.
Hi Marcos, I'd love to help but I don't sell service parts on their own, only as part of the work I do here, on equipment brought to me for service, repair and restoration. Parts can be sourced from the usual suppliers like Mouser and Digikey though modern replacements will need to be determined in many cases.
Hi and yes I feel your pain! You will likely only ever find fake 2SK97, best to move on with using two separate single FETs or a dual LSK389 or something else that matches the specs of the Sony part. Singles will need to be hand matched and graded the same of course, so you need to buy more than you need and have a way to characterise them. Duals like the LKS389 may just work as is and will be nicely matched out of the box. Try these guys, they may have something - www.littlediode.com/components/2SK97.html
The first that I saw that " monster was year 1981 when I was in Jubail ksa The weight is 50 kls with 350 watts per channel It is my " dream " up to now I just got " short of cash That's why.i was not able to bring it home when they test it with 17 inch diameter speaker The whole store was shaken because of the " base" Really up to now it's still my dream Although I've got my marantz pioneer And some " local" assembly amp but still nothing beat that monster!
They sound great but there's a lot going on in one box. The AU-9500 is a lovely thing, it doesn't have quite the balls this has, but they sound very good, possibly better, but smaller. Pre/power separation is always the way to go, if possible. Monster receivers hold a lot of appeal though!
Hi and well done on the free G-2000! Possibly some basic things to look for but keep in mind that things that are obvious to me are not to most other people. Even if you do find charred components for example, replacing them in a home environment is not recommended in most cases. The most obvious one is fuses, some will be easily visible, others will not. Beyond this point we need to get technical, so if you replace 3AG/M205 fuses and they blow again, just take her to an expert for a repair. Every piece of electronics of this age will need professional attention, service, adjustment, lubrication and so on and it makes sense to do all that whilst it's in for repair.
Is the "protection/regulation board" the same as a power supply board? And are those "driver" boards the same thing as an amp board? Also, why isn't thermal paste used on all of those transistors lying on their backs? Is it because they have the silicone washers? Also, it would have been nice to have the bulb replacement on video just because there aren't many Sansui videos.
hi,i have a Sansui QRX7001 quad receiver and the front left channel has stopped working plus if set to "phono" i get very loud "popping" sound through speakers,is this an easy or inexpensive repair? thanks
Hi Jason, hard to estimate a repair cost without seeing and properly testing and diagnosing your unit. These quad receivers are complex and often present with several faults. I worked on one recently and it also had suffered output transistor failures. If you are anywhere local to Perth though, get in touch and we can book her in and figure out exactly what the problem is for you and go from there.
at 5m45 you mention the left driver board F2806 has no lid (compared to its sibiling on the right side.) I don't remember the exact phrasing, but from the service manual - this was designed that way, and it has to do with the proximity of the tuner
Hey dude, nice repair vid. I was just wondering what brands of electrolytic caps you would recommend for this type of repair...or any audio repair come to it? Cheers, Mark
Hi Mark, glad you liked the video. I use a range of lab and mil-grade capacitors, and my choices depend on customer budget, equipment type / value and where in the circuit a part is going. In general I can recommend Panasonic, Nippon Chemicon, Elna, Nichicon, Epcos, Vishay, Kemet etc. Remember though that all manufactures make ranges of products, from cheap through to expensive and really good. You need to consider usage in-circuit, ESR, ripple current, voltage temperature and so on.
Hi Reuben, thanks for your kind words. The best advice I can give you is that if you don't have a lot of experience, take her to an expert with the experience, tools and test and measurement equipment to get the job done properly. If you have a variac and can measure transistor gain, ESR, DC offset and quiescent current, then by all means have a go yourself. Things to look for are noisy transistors, transistors that have drifted in terms of hFE, leaky capacitors, fuse resistors that have gone high, dirty contacts and connectors and noisy switches and controls. This particular G-9000 is still running strongly for my customer and almost everything in these great old units is fixable. Good luck and get in touch via my website if you have other questions.
Hi, I'd be happy to assist if you live locally and can get your receiver to me for inspection. The protection light indicates and fault and is saving further damage from occurring. It needs to go to someone able to test and trace the fault/s, don't be tempted to mess around here if you don't know what you are doing, the right technician will be able to sort this for you though!
Agreed, very interesting! I have a customer out there somewhere who is meant to be bringing me an SX-1980, don't know anyone with a 22000 or 33000 yet though...
@@LiquidAudio The Sansui G22000 weighs 92 pounds. The Sansui G33000 weighs 101 pounds. The Pioneer SX1980 weighs 78 pounds. So the Sansui's were built better. Also Sansui made some amazing integrated amps and tuners in the mid to late 70s. My friend has the Sansui AU-9900 and Sansui TU9900 tuner from 1976 and they sound great. The Sansui TU9900 and Sansui TU919 are 2 of the best tuners i'v heard. The only better tuner i'v heard is the Yamaha CT7000 from the 70s
Hi Dan, thanks for the specs. I'm familiar with them, I work on all sorts of the craziest gear as youll see if you check out my channel and website, but I'd like to work on one for sure! I agree that the Sansui tuners you mention are two of the best out there. I actually run one of the few remaining full tuner alignment workshops anywhere. My modified Marantz 125 is one of the very best tuners I've heard. Killer tuner when properly aligned and tweaked. CT-7000 is very cool!
Another guy that has a vintage audio repair channel had both at some point. I cant remember his channel but it was a video where he was working on his SX1980 and for a moment he mentioned a Sansui G33000 in the background. It'd be cool if Amir over at AudioScienceReview forum could get a really nice vintage receiver in to test against all the new stuff hes done. Just waiting for someone to send one in, people have to donate their gear and send it to him. He'll test it and post the results on the forum then send your gear back to you.
i have the same unit, but mine emanates a foul smell a little after warm up, and is constant! After 30 minutes of use i nust turn the darn thing off, ant ideas what might cause this? Purchased it non-operational, and had it fixed, and cleaned. Could a cleaner do this, or does anyone else experience this? Any insight would be appreciated...
Hi, it shouldn't smell. Smells can be caused by many things, examples of things that can cause bad smells include: contamination from previous environment, eg smoker; liquid ingress; failed or failing capacitors; contamination from low-quality / bad cleaner; insects; even a small, dead animal...! Sounds like it needs a proper clean. This takes time, the right technique and chemicals. I hope you get it resolved.
Bought an Marantz from a heavy smoker...it's the worst. I have heard of guys in the ham radio world take the tuner out and put all the boards thru the dishwasher...i do not recommend...yet...i had a devastating flood. 5 ft of cold clean water. I have a 52 amp power supply that is flawless after 6 hours under water...been working like a champ for 4 years.
i mean you never mentioned the marantz 2600 which is 300 watts per channel and about the same size as your G-9000DB, and puts out more power than the sx-1980
Those Oval Caps DO fail. I currently rebuild Sansui AU-919 and all 4 caps have capacitance between 9900 to 11200 instead of nominal 15000 uF and it is not isolated case. there is a nice video how to re-stuff those.
Hi Deniss, all caps can and will eventually fail, this is no secret or revelation. The problem is too many hobbyists adopt a shotgun approach because they don't know any better and replace perfectly good parts because they read somewhere that they 'should'. Most don't own the sort of gear to be able to properly test capacitors, leading to a proliferation of shotgun parts replacement. If a filter cap is bad it should be replaced. If it isn't, it shouldn't, unless there is a technically valid improvement being made. I've seen and worked on thousands of vintage Sansuis and others @ liquidaudio.com.au. The filter capacitors in most, but not all, were fine.

Sometimes I do, but my focus on our core business of customer repairs, and my resultant lack of time and energy mean my videos are made very quickly. Even with almost zero editing, I can barely get them out!
I bought one of this for $50 DLS, I was Dusty it turned on but not sound, I took it to the electronics guy for repair and He make it work the sound, but when I put it to test with the RUclips Left and right channel I noticed that just right channel is working, it doesn't matter if you connect the speakers to either Aor B idiot outputs it will show in the test just right channel is outputting sound, don't know what to do, I already paid the guy $230 dls and He didn't fix the problem, He doesn't understand me , also He moved the oudio outputs from their original position, I am afraid I will have to take it to a professional place because they will want to charge me a lot!!! What do you think is the problem and possibly solution? Thanks in advance!!!!
You definitely should be taking something like this to a professional. This is a priceless, irreplaceable piece of vintage hi-fi. It needs expert attention and when properly fixed, will reward you with many more years of pleasure. Yes, this will cost money, but it's always worth it!
The first easy thing to do with these is look for that switch on the side that has the protective plastic slot piece screwed in to keep it from moving. Remove that protective piece and cycle that switch a few times. This is one of the main causes for a channel that is in and out. Clean that switch.

Purchased it non-operational, and had it fixed, and cleaned. Could a cleaner do this, or does anyone else experience this? Any insight would be appreciated...
Hi, it shouldn't smell. Smells can be caused by many things, examples of things that can cause bad smells include: contamination from previous environment, eg smoker; liquid ingress; failed or failing capacitors; contamination from low-quality / bad cleaner; insects; even a small, dead animal...! Sounds like it needs a proper clean. This takes time, the right technique and chemicals. I hope you get it resolved.
Thanks, i hope to get it resolved, do not want to sell =(
Bought an Marantz from a heavy smoker...it's the worst. I have heard of guys in the ham radio world take the tuner out and put all the boards thru the dishwasher...i do not recommend...yet...i had a devastating flood. 5 ft of cold clean water. I have a 52 amp power supply that is flawless after 6 hours under water...been working like a champ for 4 years.
i mean you never mentioned the marantz 2600 which is 300 watts per channel and about the same size as your G-9000DB, and puts out more power than the sx-1980
Bons tempos! (Good times)
An audiophile's wet dream.
Those Oval Caps DO fail. I currently rebuild Sansui AU-919 and all 4 caps have capacitance between 9900 to 11200 instead of nominal 15000 uF and it is not isolated case. there is a nice video how to re-stuff those.
Hi Deniss, all caps can and will eventually fail, this is no secret or revelation. The problem is too many hobbyists adopt a shotgun approach because they don't know any better and replace perfectly good parts because they read somewhere that they 'should'. Most don't own the sort of gear to be able to properly test capacitors, leading to a proliferation of shotgun parts replacement. If a filter cap is bad it should be replaced. If it isn't, it shouldn't, unless there is a technically valid improvement being made. I've seen and worked on thousands of vintage Sansuis and others @ liquidaudio.com.au. The filter capacitors in most, but not all, were fine.
Aren't The G22000 and the G33000 bigger than this???
Yep they are, I think I mention this in the video at some point, here are a couple of bigger receivers, but all of them, including the 9000DB are BIG units...!
@@LiquidAudio Golden era, I have a fully functional Pioneer SX-1250, I also have new stuf, but I dont change the Pioneer, its a keeper for life.
How come you never show the actual repair?
Sometimes I do, but my focus on our core business of customer repairs, and my resultant lack of time and energy mean my videos are made very quickly. Even with almost zero editing, I can barely get them out!
Absolutely insane? I would be more apt to say beautiful beyond all compare, but okay. I don't want to know how much this set you back.
I bought one of this for $50 DLS, I was Dusty it turned on but not sound, I took it to the electronics guy for repair and He make it work the sound, but when I put it to test with the RUclips Left and right channel I noticed that just right channel is working, it doesn't matter if you connect the speakers to either Aor B idiot outputs it will show in the test just right channel is outputting sound, don't know what to do, I already paid the guy $230 dls and He didn't fix the problem, He doesn't understand me , also He moved the oudio outputs from their original position, I am afraid I will have to take it to a professional place because they will want to charge me a lot!!! What do you think is the problem and possibly solution? Thanks in advance!!!!
You definitely should be taking something like this to a professional. This is a priceless, irreplaceable piece of vintage hi-fi. It needs expert attention and when properly fixed, will reward you with many more years of pleasure. Yes, this will cost money, but it's always worth it!
The first easy thing to do with these is look for that switch on the side that has the protective plastic slot piece screwed in to keep it from moving. Remove that protective piece and cycle that switch a few times. This is one of the main causes for a channel that is in and out. Clean that switch.
