Features:
The Master Series CSM45 is a 845 rear-end single-ended monoblock power amplifier (left and right channel splits), which is a high-end model of the company. The CSM45 uses two Slope-Motor alloy pre-stage transformers for first-stage amplification. The input transformer has a controllable gain and control, and the distortion is small. There is no black feedback line. The transformer is used to complete the balance input of this latter stage. 2 US GE The 12AT7 is used for the second stage of high gain amplification; 2 Russian SOVTEK2A3 direct heat triode tube is used for push amplification. This third stage amplification and second stage amplification use Danish jENSEN copper foil oil diffusing capacitor for RC coupling; 2 high The performance push transformer is connected to the push tube 2A3 for low distortion, and the 1.5x boost output drive 845. The use of this transformer gives the 845 a more powerful drive capability, easily responding to the 845 J5 shed negative leg repellent; 2 new versions The noble 845T is power-efficient. The brand's 845 adopts the imported stone-drop screen level, which can easily cope with the screen power of 100W. The sound is also tbi's early dawn 845 gorgeous extravagant; 4 early Chinese 5Z4P do the electron tube The delay characteristic of the side heat pipe is the precious 845 power bile time-delay power supply, and the two-pipe parallel application guarantees sufficient energy. In order to get the signal-to-noise ratio of the island, the 845 and 2A3 are all DC power supply, and the 2A3 filament and high voltage are also designed with a voltage regulator circuit, which makes the machine stable and low noise output push-level sound is very small, and the whole machine uses two 400W power transformers. The power is large. The output transformer is a large-scale vertical installation with a power of 50W. This is a special transformer designed for the 845 straight heat pipe. Although the precision inductance is as high as 9 layers of windings, the leakage inductance is 3000V or more. Withstand voltage, this is the key to the sound of the core components of CSM45.
The circuit uses a 5-stage amplifier with high gain The powerful machine can easily drive the front-end CD without the addition of the pre-stage CD. For this purpose, the stage-type potentiometer is designed for gain control. The use of the transformer greatly improves the performance of the whole machine, and the 845 drive is solid. Will not be weak because of eating, no big loop, no transient, no compression, true natural output every detail #845 tube 1000V B pressure application, let the power of the latter stage less than 5% distortion When it reaches 28W»In the same kind of A1 class 845 single-ended circuit, the output has reached the maximum. There are 7 powerful sounds. Naturally calm and smooth, plus the inherent calmness of the 845 is not a -ft audio tube.
The feature of the CSM45: calm and heavy intermediate frequency, high-frequency and meticulous, has a certain power reserve, the driving force is obviously better than 300B, playing the symphony is not worried about the power, it can be said that this is a relatively discerning speaker and music Software very adaptable HIFI single-ended amplifier.
Equipment matching instructions: input impedance 600 ohms (unbalanced) 150 ohms (balance), this machine is suitable for matching with sensitivity greater than 86DB plus bookshelf or floor speaker for monitor speakers, horn speakers, full-range speakers, classical paper cone large-caliber speakers, small Britain The caliber bookshelf speaker has a comprehensive performance of the fan, and once used this machine to match the BL4344 second generation, the overall effect of the Yamaha NS1000 is very satisfactory, and many of the counterfeit crystal machines have not been able to surpass the quality but only have their own characteristics. The machine output Impedance 4Ω and 8Ω square ohms should be connected to the 8Ω output terminal. JR uses the secondary winding of the output transformer.
