The Pioneer SM-B200 (and the closely related SM-B200A) is a highly collectible vintage stereo vacuum tube receiver built in Japan in 1961. It is widely considered by audio historians to be the very first stereo receiver ever manufactured by Pioneer. It features striking, 1950s automotive-inspired front panel styling and was built during the era when Pioneer was transitioning away from its original company name, Fukuin Electric.
It delivers a modest, warm 15 watts per channel (some restored benches measure it closer to 8 to 10 musical watts).
