Technics SA-303 (Years unknown)

Little is documented about the Technics SA-303 beyond its appearance in Technics' own early-1980 receiver comparison advertising. A full-line ad in HI-Fi-Stereo-Buyers (March 1980, p.76) shows the SA-303 as the middle model of a five-receiver lineup — SA-101, SA-202, SA-303, SA-404, SA-505 — with a suggested retail price of $280 and a rated 40 watts per channel across 20–20,000 Hz. That placed it squarely between the 30-watt SA-202 ($220) and the 50-watt SA-404 ($350) in both power and price.

Beyond that advertisement, the record is essentially bare: no service manual, independent test report, or production dates have been captured in the Archive, and details such as THD, load impedance, and inputs remain undocumented. What can be said with confidence is that the SA-303 was a moderately powered Technics receiver sold around 1980, pitched to buyers comparing receivers on power, performance, and price.

Suggested retail price: $280 (period advertising)
Power: 40 W/ch, rated bandwidth 20–20,000 Hz
Lineup position: between SA-202 and SA-404 in Technics' five-receiver series
