Sansui 5517

Not much is documented about the Sansui 5517. It's a compact receiver rated at 12 watts per channel into 8 ohms. That's modest power, which points to an entry-level or second-system role.

What the record does show:

Power output: 12 W/ch into 8 Ω
Dimensions: 424 × 138 × 287 mm (16.7 × 5.4 × 11.3 in)
Weight: 8.5 kg (18.7 lb)

Nothing is documented about the 5517's inputs, circuit design, or market positioning. What the page can say is that it's a basic, solidly built receiver from a respected Japanese manufacturer.
