Mcintosh MC275 Upgrade KT884 Tube Power Amplifier HiFi Push-pull Class AB 75W2 Basic /Upgrade Version. 110V and 220V Optional, Please notify when you place order. Description: - There are three cow combinations in the copy of Mcintosh MC275: - One is the power cow and the other is the output cow. The coil reaches 16 layers (the original Mcintosh MC275 is 12 layers) UP-OCC (single crystal oxygen-free copper) group cross winding method - The purity of single crystal oxygen-free copper can reach 99.99, reaching a high level.After the winding is completed, it will be sent to sine company for freezing treatment after the metal is processed at low temperature, the crystal arrangement is disturbed and the molecules recombine. This kind of transformer has the advantages of good broadband response and low distortion. Using high-cost materials, the weight of the transformer reaches 33kg, and 3 transformers account for two-thirds of the weight of the machine - Such fine material selection, winding, and special freezing treatment make the power of stereo single-sided up to 75W, and serial mono-channel up to 150W, which is equivalent to 800W of vacuum tube pre-amplifier-transistor power amplifier - If the huge thrust is powerful and demeanor, but it still retains the smooth texture of a vacuum tube machine, it has an open and wide sound field, listening to the large-scale orchestral music is especially wonderful, you can easily feel the hierarchical voices, the undulating dynamics in the music Thick and full sound bottom, rich and strong low frequency, near music is full of power and vitality. 1: 1 copy McIntosh mc275 circuit All solder is German WBT solder, Each capacitor resistance wire is welded to 275 through selection and matching. The overall distribution of the line is reasonable and orderly.
The good consistency and integrity of the neat circuit for the good machine are the guarantee of the quality of the product. 1: A total of 3 transformers (1 power supply voltage transformer and 2 output transformers). 3:12AX7A Vacuum tube×3 12AT7A Vacuum tube×4.
4:Negative electrode terminal (black). 5:Positive electrode 4 ohm 8 ohm 16 ohm (red).7:Negative electrode terminal black. 8:Positive 4 ohm 8 ohm 16 ohm (red). 9:XLR Balanced signal input (requires pre amplifier drive). 10:RCA analog signal input (no need to drive by the pre amplifier). 11: Mono output mode/stereo output mode. 12: Balanced input selection/unbalanced (RCA) input selection. 13: Left channel volume adjustment (only for RCA analog input mode adjustment).
14: Right channel volume adjustment (only limited to RCA analog input mode adjustment). Usually it cost about 35USD-50USD. If you receive defective item, please kindly notify us within 14 days.
