He received it and he reports that it was a broken solder joint.  When he re-soldered the joint, the distortion went away.  He readjusted the DC offset and bias and has shipped it back to me.

 

So, the morale(s):

 

* If you are looking to fix an audio problem in vintage electronics, be sure to look for bad or broken solder joints.

 

and

 

* Shipping of old gear is liable to shake something loose.

 

And it is cool that the guy wanted to stand behind his work...

Awesome story.

 

 Does it break any forum rules to list the seller's name?  I think that in the world of vintage electronics it's nice to know that someone on "The Bay" operates like that.  I'd surely buy something from him rather than another seller knowing how he treated you.

Okay, I received it back, and tested it with headphones and speakers, and now it is clear and crisp.  So, here is the link to the guy on ebay:

BTW, comparing the fixed and recapped Sansui AU-417 to the aged Kenwood M2A:

 

The AU-417 has a hair more clarity, while the M2A has more bass and dynamics.  The former may be due to the recap, while the latter may be due to the significantly higher power reserve.

 

The M2A has really excellent "PRaT" (Pace, Rhythm and Timing), it really gets your toe tapping.

 

While I did test the AU-417 with speakers, I have not yet done so with the M2A, because I am still trying to figure out the weird speaker connections on the back.  When you turn them all the way, they only lift up enough for a relatively slender wire...

Hey guys, has anyone had any experience or knowledge on the Sansui AU 999? Theres one at my local pawn store for $139. I was planning to run my LCD 2s out of it.

my Kef 103/4's sound really good with my Marantz 4240 but clip and oscillate way too easily. Is this because they are 4Ohms? it does it really bad in 2X40 but I'm running them in 4X17 as per some advice I looked up and I can get a little more volume with 4x17 before it clips too bad. 

It never did this with my B&O S45's but those were 4-8Ohms. Should I just not use them with the 4240? I had them hooked up to my Kenwood KA-7100 and they never clipped on the same songs.

I wanted to share a collateral damage found during ebay search :

 

http://www.ebay.de/itm/Vorverstarker-Toshiba-Aurex-SY-A88-Selten-/200959090916?pt=DE_Elektronik_Computer_TV_Video_Elektronik_Verst%C3%A4rker&hash=item2eca1860e4

 

While searching for more info on this ultra rare piece, I stumbled upon a well documented primer how a good restoration of vintage electronics should look like and what it should cost :

 

http://amp8.com/tr-amp/toshiba/sy-88-23.htm

 

Now, of real interest is this one:

 

http://www.ebay.de/itm/Endstufe-Toshiba-Aurex-SC-A99-Selten-/200959150777?pt=DE_Elektronik_Computer_TV_Video_Elektronik_Verst%C3%A4rker&hash=item2eca194ab9

 

31,5 kg brute, switchable Class A/AB, in Class A still 2x 50W/8 ohm. These Toshiba Aurex are rare as hen's teeth, in USA due to Toshiba submarine scandal embargo in 80s most probably next to non existent. The combo cost in Germany cool 10.000,00 German Marks, roughly an equivalent of five grand US, which was anything but pocket change in the 80s. It was a reference combo by quite a few German magazines at the time - over competition from US and elsewhere.

 

If you look a bit closely, Toshiba did use much above average level of film capacitors in this preamp - power amp should not differ in construction quality.

 

This listing is going for the second time - with added "No shipping to Russia" mark. I assume first time around the winner was from Russia and things went sour with shipping costs. Remember - power amp without shipping carton alone weighs 31,5 kg ...

 

IIRC, preamp was roughly 500 and power amp roughly 800 Euro - but you probably still can find the exact prices if really interested online.

So question guys. A friend of mine is giving me his Technics SL-210 Direct Drive turntable (not the SL-Q210). I was thinking of putting an Ortofon OM-10 Super cartridge on it. Now in terms of both phono and headphone amplification, I was thinking the best way at present was to go the old vintage route. I did find an SX-580 receiver a while back, but was unable to make the trip to see it. However this thing has been up for a while, and I wanted to know two things:

 

1. Is it worth his asking price?

 

2. Would the headphone amplifier port be able to drive my 600 Ω headphones?

Can anyone recommend a cheapish amp to pair with my LCD 2s? I want neutrality and deep bass slam.

Midrange pioneers. Sx-650 to say 850. Dunno whats available in OZ.

this is good IMO. Pioneer makes a good pairing. The lcd2 already is a touch dark with great bass. The Pioneer x50 series will pair nicely. If you could get a 1050 that would be wonderful but it will probably be out of your budget.

What about a Pioneer SA-5300?

Yes and yes. Offer $100 cash in hand.

EXACTLY - without a restoration, the age and condition of any given sample may impact the sound more than anything else.

 

I agree with this completely - but to really make a fair comparison you would need to restore the 1280 and 1250 and listen to both via blind test.  Probably not realistic unless you have unlimited funds (of course I seem to be buying stuff with limited funds anyway) and lots of time on your hands.  So my fallback would be to restore the 1250 as there are so many positive comments on this unit on AK and elsewhere - more than I have seen on the 1280.  Just my two cents - no right or wrong here as long as you are having fun!

What about physical cleaning of the inside (as opposed to Deoxit, which is well documented in the primer on AK) ?  For example, my new M2A has a lot of dirt, which is not loose.   I am guessing kept in a room that had some occasional grease in the area, like an open kitchen/dining/living arrangement, so just enough grease in the air once in awhile, to make the dust stick.   Any suggestions?

 

 

post #9703 of 13877

Wow, that's going to be difficult. No way around it I don't think and no special products that I know of to help. I'd say you're looking at getting out and old soft toothbrush and spending a Saturday afternoon applying some TLC.

post #9704 of 13877
Yeah that's a LOT of dirt. I would use a washcloth (or 7) with some Windex multi-surface applied to the cloth very sparingly, and then let everything dry out a LOT before powering back up.

A small soft, clean, narrow paint brush or soft tooth brush like Matt said to loosen up the dust - then a careful vacuuming out of the loose dirt with a brush attachment.  A pain, I have done it many times.
