I'm a proud owner of a SX-1280, one of the best receivers ever made along with the SX-1250 and I have one of those also. I also have an SX-980 as well. These are truly works of electronic art from the late 70's. They really don't make them like this anymore unless you are spending mega-bucks. If you can find one of these don't hesitate to grab it, awesome piece of Pioneer high end

Outstanding well built example of Pioneer's best! With plenty of headroom power to spare - a very user-friendly and intuitive design that is timeless. Very proud to be an owner of one of these - and plan to keep it for a very long time. If you find one in decent to excellent condition - BUY IT!

re: SX-1280

Downloaded the service manual for SX 1280, it will show only the first 41 pages and nothing after that!
Any suggestions.
Thanks

re: SX-1280

The manual is split into 3 parts, service, schematics and additional service. You need to download all 3.

Thank you! The light in the darkness,HiFi Engine.

I was able to fix a Pioneer 1250 receiver gone dead a few months ago,with schematics from your library. Now its time again,a Pioneer 980 receiver this time,and fortunatly I have found schematics for that one too right here at HiFi engine. Sure hope it works out good as last time.
