If you need some right away, your friendly local Radio Shack will have it. A small can is good for two or three receivers, depending on how many pots and contacts you need to clean.

 

You can get it cheaper online, assuming the added shipping isn't excessive.

Thanks for the info!

Hey guys - well, brought the Sansui home tonight, pulled the case off, cleaned the pots with cleaner & lube, dusted it out and etc... Fired it up and sounded pretty good... but... there's a weird problem.  There's stereo, but not the complete band.  Playing Sade, Hang on to your love, there's the first 45 sec or so where that guitar (telecaster?) alternates between the L and R channels.  Well, when it's on the L channel, you can only hear an echo of it on the R.  I tried to run a line out from the computer to another input and it did the same thing. Seemed that the drums, bass guitar, vocals, cymbals all were ok, just that particular band was off, and it must be a pretty tight band of frequencies I guess.  Any ideas?

Well... that's crazy... it stopped... ran a bunch of test tones through the channels and must have bust some electrons loose... or the contact cleaner finally dried... L3000.gif

I've dusted off some headphones that I can't find out anything about and I'm hoping you guys can help me out. I got these as as an afterthought at a yard sale when they were thrown in with a receiver. 

What can you guys tell me about a pair of JVC HP-660. I was able to find 3 pictures online, but they didn't help much- here's one.

Does anyone on here have any experience with the Sansui G-7000 as a headphone amp?

 

I just stumbled across this thread this morning and just skimmed through a few pages, but never got around to trying my Mad Dogs on the G-7000. Been running around like my head chopped off today.

 

Anyway, I have a mint beauty that I would love to try. If anything, if it performs really good, I might just make it the main amp for my rig.

 

Any thoughts?

 

And a pic...

Any thoughts? As a matter of fact, I do. That's some beautiful iron!

You already have the G-7000? Well then by all means try it, man!

I did have a G-7000 for a while recently. It sounded great with speakers, but unfortunately there was too much hiss with headphones. And unlike my Sansui 9090DB, engaging the Muting did not reduce the hiss. But that could have just been my sample, which was nice, but not serviced in any way.

I had the same issue with my au-11000. Wonderful speaker amp, but outside of he-6, the headphone out was unusable. It hissed like crazy, and all the -20db button did was lower the volume. It didn't do anything for the hiss, so I ultimately sold it as well. A real shame since it sounded so good with speakers.

Well I can safely say, even with the volume up at "30" on the dial, there's absolutely ZERO hiss, buzz, hum, etc, etc present. Something else I can safely say, the headphone out on the G-7000 has some serious balls!

 

I have all tone controls bypassed and am getting loads of tight, deep bass, open, natural midrange, and extended, smooth and detailed treble. The sound stage is definitely wider and deeper than either my FiiO E11 or modded tube amp. It was an extremely good idea to try out this Sansui receiver. It makes for a great headphone amp, not to mention it looks damn sexy all lit up at night with the power meters bouncing around.

 

One other thing I want to add... The way this receiver performs, it really makes the Mad Dogs sound even more like open cans!

 

I wonder how the Sansui G-7000 compares to something like the Schiit Asgard, which was an amp I was seriously considering, up until now.

 

And here comes what's probably a stupid question, but... What do these old receivers use as the power output stage for the headphone section? Is it using the main "speaker" output transistors?

Not a stupid question at all. Most vintage receivers, yes, use the main speaker amplifier section to drive the headphones. The signal is passed through a circuit to pad it down to headphone-acceptable levels.

Congratulations on that thing. Looks great!

Would you happen to know if the 1989 ADCOM GTP-400 uses the the main speaker amp in the  same way for the headphone jack? Because the main outs/headphone jack are always controlled at the same time with the volume controll, (at all times), I was wondering this same thing. Thank's.

No idea, sorry.

Thank's anyway, doing some research on it, thought you may have known! Thank's.
