Very nice receiver, plenty of power and excellent FM receiption. Quartz locking FM reception with digital read out as well as the dial/needle. For some reason, compared to my Pioneer SX780 and Technics SA203, the G-4700 needs the Loudness boost turned on to sound right to me, where the Pioneer and Technics do not (driving the same speakers). Regardless, this has been a fantastic craigslist find for $50 and fills my garage and my neighborhood with crisp and clear classic rock!



re: G-4700

my tuning unit is seized, I think I need a new one. The stock number is 7036590, I went to Sansui's web site< but all they have is TVs. It's for a Sansui G-4700 Stereo Receiver.

re: G-4700

Hello all,

I am looking for the amp section board (F-3066). I purchased this receiver several years back for cheap but it has missing parts. The unit is in such great shape that I like to rebuild it and use it.

re: G-4700

looking for some help -

i'm the original owner of the sansui g4700. many years ago it just did not turn on, and has been sitting since. i've dusted it off and want to troubleshoot it.

no power indication when you turn it on - no lights or anything. what should be checked first???

many thanks -

re: G-4700

The first thing I'd check is the internal and external fuses...........check online for fuse locations!!
Good Luck!!

re: G-4700

I bought a Sansui G-4700 from ebay for $30 with only the right channel working. After figuring out what's wrong with the left channel, bought some audio output transistors, some medium power transistors, 4 film resistors, 1 ceramic resistor. The total expense for the replacement part are less than $25.00, with the help from my neighbor, we finally installed the replacement parts and after final review of what we made, we power it on and "BINGO" the LEFT CHANNEL was working good again and what a nice sound sansui G-4700 has. Me and my friend were very happy that our experiment was 100% successful. I'm just wondering how much would i charge if I decided to resale it?

re: G-4700

Hey Sparky, Im currently having problems with my left channel as well. It works but i have to play with the selector knob a little to get it to engage the left channel but then if it is disturbed it cuts out again. In your estimation would you say i need to go further than replacing the selector knobs and swtiches? Cheers
