Last week, I finally got the big G running again. It had been in storage for about 10 months and didn't work when I took it out in May. I took it apart to check all the fuses and relays, checked the polarity on the outlet (it was reversed FWIW) and fixed that, then set it up again. I'm not sure anything changed much apart from the voltage on the chassis, but it's back to working as well as it was when it went into storage. It has a persistent problem with the muting circuit, but playing it without muting solves it.
If anyone has hot advice on big-G muting circuits, I'm all ears.

Such a gorgeous system! Beautifully simple. Simply beautiful.
Well done!

The Big “G”—

Great to see your Sansui get the TLC it deserves. Beyond enjoyment, these receivers are so very sexy! On the audio muting circuit, no idea! Muting worked fine until two years ago. Suddenly it sounds scratchy and suspect. Maybe lack of use?

I'm not sure if lack of use is the culprit. It works at higher volumes, so I suspect something is loose/broken or maybe there's a cold solder on the muting board. It's such a pain to pull the face apart that I doubt I'll get to it this decade haha.

Another added benefit is the great exercise you get just moving the G 22000 around the house! lol

I have pulled a few muscles lifting my SX-1250 - that is for sure.

I've never owned a vintage amp, but I was always fascinated by them.
I've bought he6sev2 recently and would like to buy my first vintage amp. I plan to use both headphone output and speaker taps.
I've checked what can be obtained locally and this is the list of options:

- Pioneer SA-7500 (140e)
- Adcom gfa 535 (180e)
- Tandberg TR 2025 (150e)
- Kenwood KA-3300 (70e), KA-7100 (300e)
- Harman Kardon 330c (170-200e)
- Yamaha A-1000 (600e), A-450 (110e)
- Marantz 6010 (240e)
- Denon PMA-1500 R2 (490e), 1500AE (450e)
- I've always wanted something made by Sensui. A lot of different models are available. From the cheap ones (au-d33 90e), to the more expensive ones (au-x701 550e, au-717 1000e).

None of these were recapped. There are local people who offer those services.
What do you recommend? Are there any other models that you think would go nicely with v2?

I don't have any recommendations on those amps/receivers as I've not heard any of them but if you're just planning on using headphones with it, most if not all of them would work. I'd just make sure that whichever amp you choose can be repaired easily by your local vintage audio technician.

As far as the HE6 goes, the HP jack will not sound good. I've tried several different vintage pieces and the HP jack does not provide adequate current. You will def need a special speaker tap cable made.

I've had the Pioneer SA-7500 and the Sansui AU-717 and loved them both...........usually a big Pioneer guy (own or owned 8 of them) and the one Sansui and think either would make ya smile..........

I also agree the way to go is with a speaker tap connection. That's how I've been listening for about 10+ years with all my headphones other than the Denon's and Pioneer in my signature. I even use it with my HE-500 and it sounds amazing.

*Usually* the headphone jack on a receiver is tapped off the speaker outputs with some big resistors in series. Sometimes they are tapped without resistors. Sometimes they are a discrete output. If you can find the manuals and/or schematics, you might be able to tell from the diagram.

In general a planar headphone won't care too much about resistors in series. A dynamic headphone with big impedance swings will see some mild deviation in the frequency response (usually a boost in the midbass) and perhaps a slightly looser boomier sound due to lower damping.

Yup, even the HE400se does not like the HP jack. Speaker taps are the way to go. Here is what I use for the HE400se and HD600 on HK receiver:

Whenever I see this picture or similar, I must remind people that unless you know with absolute certainty that your amp has a shared ground on the negative terminals, do not connect them together. Delete either the green or black wire; do not have both.

If your amp has a shared ground negative, then there's no difference anyways from not having the extra wire.
If your amp has active negative terminals, then you'll short your outputs and that's a great way to fry your amp.

This little guy just arrrived, my first Marantz.

The sound it's not too warm as i expected; the lows have depth and are well controlled, the mids are rounded and well defined, and the highs are clear and detailed (in fact i had to tone down the treble a little), good separation. I love it so far; surprisingly good for a 30w unit.

Some vintage receivers tap the speaker outputs for the headphone socket and brought down the level with resistors much like that headphone speaker output adapter. My Sansui D707F (or Sansui D9) uses this method. It sounds better than most of my headphone amps but that’s due to the amplifier topology and their crusade for great measurement. It also has no band pass filter so it amplifies everything from near DC to several hundred kHz.

It’s amp section is extremely transparent that I can hear (with headphones) how the noise floor raises if I turn on the tone switch that enables bass/treble controls. Not sure if it’s because old transistors getting noisier as it ages or because of the extra wiring becomes an antenna in the enclosure.

Marantz gear was truly beatiful!

Since a pair of years I use Headphone amps for Headphone listening. But my more or less older integrated amps/receiver are again here, but more for speakers use.

That are:

Receiver Fine Arts of Grundig R 1 - New buyed on December 1st in 1994. Almost 30 years old and no repairing needed in all the time.

Ampflier Telefunken RA 200. Build in 1981 - 83, in the time of the change of the consumer electronics departement from AEG-Telefunken to Thomson-Brandt.
Buyed used in August 2009 in Ebay.

Amplifier Dual CV 121-1. December 1976. From the great age of Dual Gebrüder Steidinger GmbH & Co. , St. Georgen/Black Forest.
Buyed used in September 2010. First owner was a Hotel in Baden-Baden.

I've found (allegedly) recapped Sansui au517 locally, it's being sold for 650e.
Is that price ok? I'm still waiting for the speaker taps cable for my Hifiman he6.
I've always wanted a Sansui and this one seems like a good fit for my headphones.
Anything specific that I should check and validate before buying (I will check if dc offset is fine)?

I can also get SA8800 for 750e (also recapped).
