Pioneer SX-450

Pioneer SX-450


The smallest receiver in the Pioneer lineup during the mid to late 70’s was the Pioneer SX-450. These entry level receivers were only rated at 15 watts per channel but were still built with quality materials and craftsmanship. Sure, there were fewer features then the bigger receivers had and vinyl veneer instead of wood but the SX-450 is still a good receiver for a second system or garage stereo. It will hold its own in a smaller room but tends to lack the power for a larger room.


Pioneer SX-450


Made from about 1977 until 1979 the SX-450 retailed for just under $200.00 and, as you can see, it has the usual late 70’s look that personified the Pioneer receivers of the time with the silver face, beveled knobs and “wood” case. Inside it has the usual great Pioneer build quality. It is small so it only has 40 capacitors and 8 lamps.

Pioneer SX-450 Ad


The Pioneer SX-450 isn’t something that audio collectors are going to fight over but they still have a market. Anyone interested in vintage audio on a budget would be wise to try one of these receivers before spending a large amount of money on a more expensive unit. They are also great for someone learning to restore older audio components as these are fairly simple and easy to work on. Needless to say these units do sell well.  They run from about $30 at the low end up to around $125 for one in great working condition.
