These tubes are highly sought after. Outer cage is has been sprayed very close to original paint just to preserve the condition and prevent any oxidation.Both units got services and tuned with professional tech and outputs are mirror identical. Very sweet and warm sounding amplifiers. Pair of custom banana plug adaptors are included. Original power cables got replaced do to the age and condition. TECHNICAL DETAILS From the amazing Vintage Units.
High-end tube amplifier representing Luxman's heyday in the mid 1970s which quite probably existed in fifty slightly different versions and also had LuxKit equivalents. Primary is made of four windings wound together to reduce leakage and distortion inherent to Class AB or Class B amplifiers ; the GX100-3.6 transformer can deliver more than 35W at 35Hz. Specially developped in collaboration with NEC. In Class B, the power dissipated on the plate can amount to 60W at 1Khz, thanks to its structure and high heat-dissipation metal.
Of the cathode-follower type, uses newly developped 6240G double-triodes. To rise the gain obtained by the driver stage, another 6240G double-triode is used here, with a 200V tension applied to the plate. A 5dB NFB is applied between the cathode and the 4th winding of the output transformer. Its first stage uses a 12AX7 (ECC83) double-triode ; the second stage, DC-coupled with the first, gives an out-of-phase signal which is sent to the driver stage. GX100-3.6 Quadra-Filar output transformer (specially developped for the 8045G), C1744 low resistance choke self, two 220µF electrolytic caps.
After this stage, the filtered tension is applied to a bridge rectifier. The Luxman MB-3045s are relatively compact, measuring just 8.5 inch deep, 14 inches wide and 6 inches tall. The front panel has only a bright-orange power indicator (the lit vacuum tubes also indicates that the juices are flowing). Around back, the configuration is relatively Spartan: a simple barrier strip for speaker output, with 4-, 8-, and 16-ohm taps, a solitary RCA input jack and a level control, along with a two-prong power cord receptacle.
