I have own this for quite a while now. Power, reliability and smoothness and massive heat sinks, I can only add (a) Bravo to Pioneer Electronic geniuses (b) I wish to go back to the products of the past that is pure unadulterated and organic music (not Synthesized)

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

So, I dug my SX-1280 out of the attic so as to use it at a party and all it does is click after turning power on. It worked fine when I put it in the attic so I was really taken when it suddenly decided to do this when not even being powered. Awesome amp, so I don't want to get rid of it yet.

Anyhow, I am not overly savvy with electronics but have some capabilities and would like to find if someone knows where I should start to look.

As stated, I turn on power and it clicks some protective circuit about every 3-4 seconds. No sound is ever heard. The clicking sounds as if it is coming from the left side around the area between the metal top and the wood.

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.

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.
