Calling All "Vintage" Integrated/Receiver Owners
Jun 12, 2011 at 6:02 PM Post #1,576 of 19,145


Today I was fortunate to insert a new Bel Canto 1.5 blackface DAC into the lineup.

Using the great Sansui AU 20000 as a preamp for the Pioneer M 22 driving a 1975 Stax SR-X MK3.

Bel Canto is fed via spdif,old meets new seems to work and sounds just fine,thanks.

I actually have both an SA-7500 and SA-8500 (both of which are now rather far from prime condition, unfortunately) and know of an SA-9100 available locally. 
 
Would you say that your SA-x500 amp is tonally brighter than your SA-9100? Is there anything you like more about your 9100 than your 9500-2?

Maybe a tad brighter, but, if it were me I would take the 9500 over the 9100 because it has dual transformers, haha, and the capacitance control is on the front and not on the back like the 9100.  I do like the overall look of the 9100 over the 9500, the wood accent is a nice touch.  The 9100 also have gain controls, -15 and -30dbs for volume.  In terms of size the 9100 is a smaller amp.

Some vintage amp has huge cylinder protruding on top of the case.  The manual said that they are electrolytic capacitors.  Are those capacitors of that size still available?  Or they are huge just because of old technology, so we can replace them with much smaller but similar rating ones?  My concern was the possibility of find replacement parts.

Regarding capacitors, size will be smaller.  However, my tech says capacitors either work or they don't and him personally he would not suggest a complete recap unless it is needed.  Rather, he would just replace the caps that need to be.  He's an honest guy.

Your repair guy is right. Capacitors aren't like resistors that can go out of spec. As long as there are no leaks they are fine. But there's nothing wrong if you're replacing them with better sounding capacitors. And doing a complete recap job may not be necessary, but since the caps are so old, it might not be a bad idea to do a full recap in case some do go bad in the future. At least that way you may be well covered for the next 20+ years.

That really is a sexy looking setup. I bet those sr-x mk3s really sounds excellent with that set up. I'm been thinking about moving my stax rig to my vintage set up as well.

1979 Pioneer M 22 amplifier.

Twin mono block design,left and right channels on one chassis and a tube crusher at that.

Drives all the Ohms and sounds good doing it.

Still listening to the sweet girl,the better the source the finer the music,so true...

So I'm reading up on the general cleaning of the circuit boards and I come across the suggestion of cleaning a dirty volume control that is sealed.  The author has drilled 2 small holes to introduce Deoxit into the volume pot,  Anyone ever do this themselves?

Score!!
Help!
Now I need to decide which one to keep (SX1250, AU 717, Toshiba 7100). Or else come up with a reason to keep all three (for the wife). I think I got a good deal on this one, $300 from the original owner and an hour drive to pick it up.
Listening to speakers right now, and my B&W CM1's have never sounded this good.

$300 for the SX-1250? sounds like an awesome deal. I bought a SX-950 on eBay for $250 after shipping. I will trade you for the 950. You can tell the wife it is smaller, therefore no big deal to keep around.

Seriously though, let us all know how they sound with the LCD-2. I thought about picking up a AU-717 off eBay as well but resisted the temptation. That an a Fisher 500C. I must admit, the reason I don't have that one is less resistance and more the fact that I was at work when the auction ended.
 
My SX-950 will be back from the shop tomorrow, maybe I can snap some pics of it soon.

No doubt, in good condition $300 for an SX-1250 is a major score.  Nice work!
 
Oh, and I don't know anything about the Toshiba, but for sure you have to keep both the Pioneer and the Sansui :)
