mb-3045_____________-o-en1-920-lux维修电器原理图

Up until lately.it had been supposed that output triodetube would have neither sufficient output power norefficiency.Therefore."LUX"has cultivated and completed a new output triode tube which has high ef.ficiency and huge output power (in collaboration withNEC.Shin Nippon Denki).And consequently.the tube8045G can easily offer huge 60w under the"Class A"push-pull configuration.The tube power amp MB3045is a monaural Basic amplifier,adopting this 8045G at theoutput stage.In this amplifier.to utilize the outputpower of 8045G to the maximum,we designed the newoutput transformer GX100-3.6 of "QUADRA FILARwinding system and the cross-shunt push-pull outputcircuit.To drive this output circuit.we need verypowerful drive circuit.For this purpose employed arecascode-follower direct-coupled drive circuit,high voltagepre-drive circuit in combination with the newly designedhigh voltage driver tube 6240G.Thus,our efforts forcultivation of these new components output tube.drivertube and output transformer -and the technique tomake the most of these components made it possible toattain the high output and low distortion.With naturalcare,it will give you many years of outstanding performance and personal delight.Please read this Owner'sManual carefully before operating the unit.which willgive detailed descriptions and operating procedures forthe electronic and mechanical components of theMB3045.Thank you for your selection,and may"goodlistening"be your daily pleasure.
