Sansui G6700 question

[J. Matt]

Hi, I’m new here and to audio forums generally. I have a question (two really) about my G6700. I’ve had it for years and it has been reliable, if a little fussy. The issue that is causing me to bug you folks is a selector switch that is having problems keeping both channels working (mostly the right) on its two phono positions; all other positions work.

This and some occasional noise caused me to take it in to the person who I think may be the only local repair option for something like this. Opening it up to spray some contact cleaner on the switch was above my pay grade once I saw the tuning pulleys, etc. hiding the switches. (I am a photographer with a reasonable amount of experience repairing mechanical cameras which was required of anyone using large format equipment, not a stereo electronics tech which may be voodoo for all I know!)

The receiver was returned to me with the issues with the tone defeat buttons fixed which was also probably just a soak with contact cleaner, the display lights newly out, and the selector switch still not working properly. To his credit the guy I took it to is definitely qualified, maybe even an audio savant, but facing imminent eviction as the whole block he is on is being taken for a huge redevelopment project. He was trying to find a place to move and stressed. I tried to contact him but didn’t hear back.

How hard is it to get at that selector switch? Re-light the display lighting? (The tuner LED is still working.) Is this something someone like me can tackle? I tried to find a similar case on this forum and ran up against how fussy these are to fix which spooks me; I’m busy and have enough projects hanging over my head. And I’m in Honolulu where the pool of repair people for stuff is small generally, never mind 35+ year old audio components!

Thanks so much in advance for advice/help/referrals! I can’t see getting rid of this, I do and have liked it for a long time and it sounds good, at least to my damaged ears. Plus as an environmentally-focused documentary photographer I work to consume as little as I am able to and repair as much as is possible.

Aloha,
Jaye

I think you would get better responses in the "Exclusively Sansui" sub-forum than here in "Tuners", which is pretty specific to tuner performance and repair issues. A short answer to your question about doing it yourself would be that if you actually have to mess with the tuner to repair the lamps and switches then it is probably something you don't want to do yourself (but, hopefull,y you will not have to do that).

I think the Sansui forum is where you're most likely to find people familiar with this particular unit. If you want to have the thread moved, click on the "Report" link at the bottom of your post and ask (a moderator) for it to be moved (and where). You can also leave it here and see what you get, though.

You can find a service manual for the G6700 here.

Thanks for the advice! I’ll see about moving it. And thanks for the link to the sercice manual, but I’m pretty ok with not doing it myself having seen the tuning set-up in there.

Thanks so much to whoever moved this into a better forum thread!

Hi J.Matt,

I had a G6700 for many years, sold it recently. But as I recall, the front panel lights are only two, one on each end of the front panel; they may be wedge-base 8v lamps plugged into a socket. If they are burned out, you can get replacements from another AKer known as djwojo. He's the bulb guru! I had to fix the wiring once, the bulbs were good but the power to them ended up being a broken wire.

The function switch should be easy to get some DeOxit cleaner into it, by removing the bottom panel. It's just to the right of the tuning knob when viewed from the front. Don't use a generic "contact cleaner"; some of these are too aggressive where plastics are involved...get some Caig DeOxit D5 and spray it down with that, then rotate the control through all its positions about 15-20 times. That should clean it up. Also good for all controls, volume, balance, bass, treble...it won't hurt anything.

Best of luck! Let us know how your G6700 progresses...
