The Sansui G-9700 is one of the best receivers ever What made your Sansui receiver unique was it had the digital display to go along with the analog tuning knob. Most receivers from the 70s just had the analog tuning knob. Having have the digital display was great cause it made sure you were exactly on the station you wanted. What's interesting even the top of the line Sansui G22000 and Sansui G33000 didn't have the digital display where the G-9700 did and the models below it Sansui G-7700 and Sansui G-5700 had the digital display with analog tuning knob.
I grew up listening to a G9700 paired with 9700 speakers. Beautiful receiver/amp. Oh the good old days. Used to crank heavy metal out of that system and the neighbors used to complain lmao ! Btw, Love your vidds Andrew ! Keep em' coming !
I just picked up a G-8700DB and is in like new condition. The only flaw is that 4 led lights are out in the red power meter display. Can this be repaired or replaced? Thanks! Where are you located?
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.
Oddly enough, they're better than these in a few ways including one way that is important: They're more reliable due to the bias circuit thermal tracking the output stage heatsink instead of the driver heatsink. It's also less complex and easier to service over all. The cost is FAR more reasonable as well.
John Leaf It's not a button; it's a plug. Remove the plug and align the arrow to the required voltage. If the exact voltage is not available, select the higher neighbouring voltage. People on 200-208V systems should use the 220V setting; and if you have 230V mains, use the 240V position. There will be a very minor loss of power output (
10% of the shipping weight was due to packing materials! I start with a double wall box, line that with 25mm/1" Styrofoam, and then wrap the receiver in bubble wrap. Corners are bolstered with tubes made of bubble wrap and any gaps are filled in with Styrofoam packing peanuts.
These receivers actually have switch positions for 220 and 240V. Nothing bad will happen other than slightly reduced output power if it's run on 220V in the 240V position but the reverse will cause higher than spec internal voltages to the power amplifier which can exacerbate the overheating problems that these receivers sometimes. You'll be right on the edge of the 10% tolerance with no margin, which is not good for it. The preamp and tuner will receive the correct voltage regardless due to a regulator circuit, but the regulator will likewise run warmer if powered from 240V on the 220V setting. The 10% deviation won't be immediately harmful however so this can go unnoticed for a very long time. I advise EU residents to use the 240V position to be on the safe side but they can run either as 230 is within tolerance of both settings. Use the 220V setting for higher power, the 240V setting for longer transistor life. US and Canadian users should NEVER use the 100V setting; that's for Japan only and you will have 20% overvoltage on all rails if you try the 100V setting on 120V. This will lead to rapid wear of the voltage regulators and the power amplifier. I see this from time to time at home here in the US and the boards in such units show much more thermal stress than normal.

Beast!
Know of any techs in Florida or Georgia. Thanks...sansui G8700 DB.

Its like night and day the build quality of the g 9700 to the g 9000 .
They both have their issues and their merits, but the G9000 is the one to have if there's a choice.

Great video! What are your thoughts on the G-7700?

How do i change the voltage from 110 to 220v? the button seems locked, much thanks

What does it usually cost to restore these receivers?
It's not cheap. It involves multiple full work days of labor with expensive parts and is around $1200 as of 2024.
What about when you select loudness button?
Maximum power output capability remains the same; the loudness just adds a volume dependent bass and treble boost.
Curious how you pack one of these beasts to survive shipping.

Andrew, thanks for replying!
Puedes ayudarme
I regret selling mine for $550 in '10
eu is 230v but called 220/240v
waw 250watt amazing at 8 ohms :)
