About the MB3045
The Luxman MB-3045, produced from 1975 to 1978, is a classic high-end tube monoblock amplifier featuring a push-pull design with specially developed 8045G triodes in collaboration with NEC. It delivers outstanding detail, authority, holographic imaging, and depth, often compared favorably to renowned amplifiers like the McIntosh MC30. Original 8045G tubes are rare and expensive, leading many units to be factory-modified for KT88/6550 compatibility. Compact with a caged chassis in chocolate brown or black finish, it includes a bright orange power indicator, RCA input, level control, and speaker taps for 4, 8, 16 ohms. Built during Luxman's golden era, it uses a Quadra-Filar GX100-3.6 output transformer to minimize distortion.
