BigBusa Posted January 27, 2002 Share Posted January 27, 2002 I think I've found the ultimate receiver to feed my cornwalls and heresys! This pioneer sx1280 is 185wpc! Talk about oooomph! It weighs 68lbs! They don't make em like this anymore. To bad it's not 5.1 ...I can't have everything though! Excuse the bits of masking tape on the glass. I need to scrape that ASAP.

mobile homeless Posted January 27, 2002 Share Posted January 27, 2002 Jesus...that thing has more knobs and gadgets than an F-16 cockpit! Lordy. Supposed to have decent tuner as well. Sure is a beast. I had a 70s Pioneer receiver for awhile and loved the big, bold sound of the day. OF course, it was missing a lot of refinement and was surely not as transparent as other offerings. But pretty good considering the era. Also had a Yamaha CR-800 which was another nice sounding unit. Tube will expose what they dont have ...but still, BEASTS of the daY! ------------------ Phono Linn LP-12 Vahalla / Linn Basic Plus / Sumiko Blue Point CD Player Rega Planet Preamp Cary Audio SLP-70 w/Phono Modified Amplifier Welborne Labs 2A3 Moondog Monoblocks Cable DIYCable Superlative / Twisted Cross Connect Speaker 1977 Klipsch Cornwall I w/Alnico & Type B Crossover system one online / alternate components / Asylum Listing f>s> Quote Link to comment Share on other sites More sharing options...
Mike Lindsey Posted January 27, 2002 Share Posted January 27, 2002 It looks a lot like my old Sansui G8000 that I bought in 1978. I just love the brushed aluminum look. Let us know how you like it with the Cornwalls... Mike ------------------ My Music Systems Quote Link to comment Share on other sites More sharing options...
BigBusa Posted January 27, 2002 Author Share Posted January 27, 2002 It's incredible with the cornwalls! Now I see what you guys mean about the 1st watt being the most important. The meters are very precise on this receiver. From zero watts to 1 watt it's broken down like this ..0.01 / .1 / 1 Most of my listening is within the first watt.

mobile homeless Posted January 27, 2002 Share Posted January 27, 2002 Indeed.... Most of the listening IS within that first watt...which is why the SET amp is the ultimate. Rest assured, the 1st watt of a 2A3 or 45 amp is like liquid... Solid state not the best at the fist few watts. kh ------------------ Phono Linn LP-12 Vahalla / Linn Basic Plus / Sumiko Blue Point CD Player Rega Planet Preamp Cary Audio SLP-70 w/Phono Modified Amplifier Welborne Labs 2A3 Moondog Monoblocks Cable DIYCable Superlative / Twisted Cross Connect Speaker 1977 Klipsch Cornwall I w/Alnico & Type B Crossover system one online / alternate components / Asylum Listing f>s> Quote Link to comment Share on other sites More sharing options...
Curmudgeon Posted January 28, 2002 Share Posted January 28, 2002 The old Pioneer SX series has a great AM/FM tuner, pulls in stations much better than a lot of expensive modern equipment. If you get the pots and switches cleaned its a nice sounding, fairly quiet unit with a lot of balls. If you look inside you'll see that the caps look like Coke cans, the toroidal power supply is friggin huge, and the circuit boards are individually shielded by aluminum covers. It may be old but the build quality is outstanding, plus considering that the components are discreet (no IC's) and very repairable it will most likely still be working when the grandkids are ready for music. Too bad Pioneer hasn't made anything like it in years because there was a lot of engineering and aesthetic pride put into the late 70's flagship SX's. Your SX-1280 was made from 1979-81 and had an original retail price of $950.00 (in 70's dollars). I sure like mine, I've got two mint Pioneer SX-1250's and I even have a mint Sansui G-8000 like Mike Lindsey mentioned. I may not listen to them every day but they're all hooked up and fully functional. There's just something about a massive receiver with more aluminum than most Harleys and real wood trim, it looks like its ready to knock the pictures off the walls just sitting there. Enjoy it with your Cornwalls but don't turn it up too loud, the combined power of the SX plus the efficiency of the Cornwalls equals a visit from the cops if you're not careful (don't ask me how I know)!

ChrisK Posted January 28, 2002 Share Posted January 28, 2002 This vintage thing is really catching on. See my posts about a recent vintage tuner find ("warm and fuzzy update" and "Attn. Tuner People"). The only problem now will be all the eBay'ers trying to make a living driving up prices on this stuff...bummer ------------------ HT Klipsch KG2.5 (front & rear) Klipsch KV2 (center) Klipsch SW12 (sub) Marantz SR700 receiver Toshiba DTS DVD JVC SVHS VCR Sony Hi8 VCR 2 channel Klipsch Cornwalls (1978) Cary CAD 300SEI amp Arcam Alpha MCD cd player Quote Link to comment Share on other sites More sharing options...
BigBusa Posted January 28, 2002 Author Share Posted January 28, 2002 AudioHolic it sounds like you know your vinatge pioneers! Thanks for the run down. It sounds like you have a nice collection. This one was found in the dump outside about a month ago by my brother ...believe it or not. He happened to be dropping some items off and saw it. He remembered me telling him that the older stereos could be worth money so he grabbed it. He had no idea what it was except that it was heavy! He called me and told me he found a big heavy older pioneer at the dump. I asked if it was an SX something and he said yeah, a 1280! I about fell out of my chair! The glass is cracked, the mute switch doesn't mute and the fm + stereo lights are out but everything else works perfectly. The next day it snowed 3 inches of heavy wet snow. If he had not found and rescued it when he did the snow would have most likely ruined it. Quote Link to comment Share on other sites More sharing options...
dougdrake2 Posted January 28, 2002 Share Posted January 28, 2002 Audioholic - I'm curious about the SX-1250. Do you know where there are any specs on this unit, or do you have any? Also, what are they going for? I don't own one, but I know someone who might be willing to part with it...and you seem to like the two you have. It gets a mind to thinking, ya know???

fini Posted January 28, 2002 Share Posted January 28, 2002 In the past few months, I've found some similar vintage Sansui receivers: An 8080 DB @ the thrift store for $60, and a MINT (w/all paperwork including sales receipt) 4000 for $10 @ the flea market. These beasts make my walkman seem positively light! This can all be quite fun, if you're willing to "mess around" a bit! snowed in, fini This message has been edited by fini on 01-28-2002 at 03:41 PM Quote Link to comment Share on other sites More sharing options...
Jobman Posted January 28, 2002 Share Posted January 28, 2002 DD: I sold my almost mint SX-1250 in December on Ebay for $380. It was really clean, and had been gone through at my local repair shop, with $125 in replacement parts. Still not a bad deal, as I only paid $100 for it. The buyer used the Buy it Now and it sold after 2 days online. He was local, so we just met halfway. I also sold my Sansui 9090db, a Pioneer Sx980 and Sx1010. Now I have my AWESOME Kenwood KR-9600 and my Fisher 500C. Next purchase is a mid-price CD player for the 2 channel system. I have to use my K-horns as fronts for my HT system, but also my 2 channel. I have them hooked up to an Audio Authority Speaker Selector and Amp Selector. I don't really like this set up, as to much wire is involved, degrading the signals, but I do not know how else to run all this stuff without it. Any ideas?

Jobman Posted January 28, 2002 Share Posted January 28, 2002 Oh yea - BigBusa: Awesome find on the 1280. If I had the 1280 instead of the 1250, I would not have sold it. I still am holding out for a SX-1980, sitting unused in its original box in a closet for the past 20 years. (and get it for only $200) yea - right Mike Quote Link to comment Share on other sites More sharing options...

Mike Lindsey Posted January 29, 2002 Share Posted January 29, 2002 Here are some shots of my old Sansui G-8000... http://www.retroaudio.ru/sansui/receiver/G-8000.htm Here's another shot... http://www.oaktreeent.com/web_photos/hi-fi/Sansui_G-8000_web.jpg I loved this beast! It was built like a tank and had no problem driving my Infinity Column II's. I can't believe I sold it to get my Yamaha separates...

T2K Posted January 29, 2002 Share Posted January 29, 2002 Mike,wanted to thank you for the links you provided.My Dad and I have been talking recently about his vintage equipment and I have looked for links such as these familiarizing myself with what he has.Thanks. The old man has a Sansui 8080DB and an old Sony behemith that I don't remember the model of.He also has turntable,cassette deck,reel-to reel,Sony and AR speakers,and who knows what else.Enough wood to build a bedroom suite! All covered and pampered.He said last week he was about to donate to charity three pairs of speakers he doesn't use anymore that are just in his way!Keith to the rescue! Anyway thanks, Keith Quote Link to comment Share on other sites More sharing options...
Mike Lindsey Posted January 29, 2002 Share Posted January 29, 2002 No problem, Keith! Oaktree is a good place to find some classic Japanese receivers from the 60's and 70's. I think thry have a pretty good reputation on restoring a lot of the stuff that they sell. Retroaudio is a good resource for getting information on some of these old pieces...

Colin Posted January 29, 2002 Share Posted January 29, 2002 I bought a 48 pound solid-state (SS) monster, the Class A Pioneer M-22 reference amp, for $250 about 15 years ago because I couldnt stand the scratchy sound of my rusty Dynaco ST70s with their EL-84 EL-34?) tubes. The closest modern day Pioneer equivalent is the Elite series M-10x, which it looks more like their current receivers than it looks like my amp. My black beauty looks like the Theshold amps shown at the 2000 CES show: http://www.enjoythemusic.com/ces2001/monday/. (The new Threshold Pro company is going to release this amplifier shortly along the lines of the old Threshold T300 amplifier and priced at approximately $8,000.) The top of the M-22 is exposed. It has two hefty black transformers, square and 4 high with two black 33,000 uF capacitors the size of Foster lager cans, are surrounded by a fortress of black cooling fins. The four computer grade storage capacitors reduce power supply ripple to about 1/10 volt. The SS Pioneer is 30 watts per side, dual mono amp with dual transistor differentials built onto one chassis. It is 2-stage differential push-pull Darlington connection, direct coupled OCL. It has plentiful negative feedback in the 1st stage. I bought it cheap, new and in the box. Frequency response is from 2 Hz to 150 kHz within 1 dB. Like any solid state amplifier, the Total Harmonic Distortion (THD) is a U shaped curve. It is .005% at 1 watt into 8 ohms at one end, dips below .001% at 15 watts, curving back up to .01% at 30 watts at the other. In other words, ultra clean response. Below 10 watts, the M-22 has better THD spec than the Krell FBP 350mc at $17,000 per pair! Technically the amp can put out more than 30 watts, but the THD climbs like a rocket once output is higher than 22 watts. Hence the M-22 designation. Below one watt, the THD curve is just as high as it is above 30 watts! I plan to use this to power by woofers someday soon ... ------------------ Colin's Music System Cornwall 1s & Klipsch subs; lights out & tubes glowing!

T2K Posted January 29, 2002 Share Posted January 29, 2002 OOPS! The Sansui receiver is a 9090DB! Dad,can you write the model numbers down and call me back? No,don't care anything about those old albums.Give them to Goodwill.

JCturboT Posted January 29, 2002 Share Posted January 29, 2002 Guys, Speaking of classic receivers... I went to go look at "older" Yamaha system,late'70s.What I was really going to look at was the Yamaha NS1000M speakers for a friends system but what caught my eye was the 1979 vintage Yamaha 2040Cr receiver-a 120 watt beast with that classic '70s look,brushed aluminum and glass faceplate,wood side panels all still owned by the original owner in very good condition. I wish I had a bigger house! Jeff Quote Link to comment Share on other sites More sharing options...
