Pioneer SX-525


The Pioneer SX-525 is a medium-powered, low-priced AM/FM solid state stereo receiver with advanced circuitry and sensitive tuner section.

Stereo on a budget can have a lot of the power and a lot of the frills of very expensive stereo, as this superlative new AM/FM receiver from Pioneer so amply proves.

Offering the music listener up to 72 watts of music power, sensitive FM tuner reception, highly advanced circuitry and a full choice of program sources, the SX-525 offers more important extras than many receivers priced much, much higher.

It features finely balanced, dynamic stereo sound - and gives you more power than you'll ever really need to fill a large room with music.

Moreover, it is Pioneer-built and Pioneer-guaranteed, and in stereo that says just about everything.

I got one of these from the local recyclers...missing the little speaker connection widgets of course, but all there otherwise. I find it has a very warm and cozy sound. Not a loud receiver at only 13 WPC, but absolutely great for a small system in a den or living room. Highly recommended if you can find one!

This was my first real receiver purchased Fall 1972 and have found a mint condition. The irony is that it sounded better than any I had since. I do not believe the new equipment can replicate the reality of the music as it was meant to be heard than this series of Pioneer receivers.




Used this sx-525 since 1983 like a tuner and power amplifier for any devices.I get the nice soft "tube" sound and extrimly safe equipment!!!!Thanks to Pioneer's designers!!!!
Many thanks to "hifiengine" for the manual !Good luck !
