The Marantz 8B was first released in 1961 as a revised version of the Marantz 8, which itself was an upgraded version of the Marantz 7. It uses a pair of EL34 power pentode tubes with an output power rating of 35 watts per channel, and it produces full and colorful audio with especially notable bass tones. These units are highly collectable, so buyers should be prepared to do some searching to obtain one in quality condition.
