I was suprised in finding this site and reading the reviews on the SX 780 reciever. I was curious what my reciever would be worth after all these years. I purchased my system in March of 1979 which included a PL 514 turntable and a Pair of HPM 40 speakers. I have alsways loved this system and the quality of sound. I have had it in storage for the last few years and I am looking forward to setting it up in my office at home when the room is finished.

I purchased an SX 780 and the sound was fuzzy on FM and extreemely weak on any other imput. I replaced the darlington power packs and now I get GREAT sound on FM but no sound on anything else. I turn it to FM, wait a second, hear a click, then music. Turn it to anything else, nothing. Turn it back to FM, wait a second, hear a click and then music. Any one have any suggestions as to what could be the problme?

Build quality on vintage equipment like the Pioneer SX 780 and the Marantz 2238b was incredible. You really got your money’s worth back then. I would have been more surprised if it didn’t work LOL. Keep rocking the house and thanks for stopping by and sharing. Remember, every time you crank up a vintage stereo and some big box speakers an iPod weeps!

What a surprise seeing this site…just cleaned out the attic and found my old sx780 from 1979…
Hmmm does it still work? Yes beutifully and my kids wanted to have a dance party, so I
Plugged it into some huge 15″ Peavey PA cabinets and rocked the house with dance music…
Long live the. Sx-780!

Hi,
I have one of these…sound is very pleasing. There is some scratching noise and I would like to give it to someone to check it out if not too expensive. Can someone advise ? I live in the Ottawa area.

Thanks.

This was my dream receiver back when I worked for my cousin in Florida at his audio shop back in the late 70′s. I finally scored a great one on eBay and absolutely am loving it. Great looks and performance for the price, and still rocks great after 30+ years!

Add me to Anthony’s list.

My neighbor was moving and I pulled it out of the dumpster.

It works great. I am listening to it now.

Unbelievable how loud it can get without distortion.

You might want to look at this forum, might be able to repair it yourself. http://www.antiqueradios.com/forums/viewtopic.php?p=702464&highlight=#702464

Nice to see all the accolades for the SX-780! I just pulled mine out of mothballs, fired it up with a memory that said it wouldn’t fire up because it needed a new power board. It showed lights and amperage!!! So I pulled out my old bookshelf Bose speakers, excitedly hooked the speakers to the receiver, turned the receiver on, heard beautiful, full, rich sound, and……..it died. Evidently it did the old battery trick and regained just enough juice to show some life, but not enough to live

Question: The last power board I put in it ran me about $100 plus whatever hourly labor charge was at the time. Is it possible to even find a power board for an SX-780 anymore? Maybe Ebay, but I’d rather not go that route. The guy who put in the last power board loved working on this model, and he is still around, though not doing repairs since the business he worked with closed, but there’s always the chance he has scavenged enough parts…but that’s a wild hunch.

Any ideas out there?

Well I love the sx-780 its one of the best receivers I have owned. I have a sx-1010 and I love it too but sx-780 has a much cleaner sound. I guess when sx-1010 was made that was new to pioneer gear I got the sx-980 and that is a great receiver and it has the power it is 80 watts per ch but it don’t have the sound like sx-780 and I got little sx-780 threw a friend of mine. When I got mine it needed some work on the tuning dial, it was frozen solid. I could not move it so I took it apart and lube it and now it flies across the dial. I love that little receiver so who ever has one knows all about it. Hey enjoy yours boy i do enjoy mine.
