Known as Danwang 845 direct-heating triode, due to good linearity, low internal resistance and high power, it dominates all HI-FI tube amplifiers! But because the gate negative pressure is relatively deep -140V, the general tube resistance-capacitance drive cannot be satisfied, unless the transformer is boosted, but it is necessary to know a good performance index to promote the cow, making it more difficult than the entire 845 amplifier, due to the promotion level The current is very small, and more importantly, there is no load at the output, that is, because the 845 has no grid current, it is a voltage-driven type that leads to a very poor first-pole coupling, which directly affects the sound level of the entire machine! The shop launched a 20W+20w845 single-ended amplifier split power amplifier using the classic 6 meters 4 (K: 170) +300B cathode output drive 845 of 100V100MA. No matter from the output voltage amplitude or distortion angle, it can drive the 20W 845 power amplifier! This split machine uses left and right channel independence! A total of 10 transformers are involved in the work, 4 chokes, 4 high-voltage and low-voltage transformers, and 2 output transformers. The reason why such a complicated production process is used is that the sound field of the split machine is better than the merger because the ground wire is independent ! The separate high-voltage and low-voltage power supply is to separate the filament winding which has nothing to do with the sound, so that the high-voltage coil has greater magnetic energy, and the internal resistance of the high-voltage winding related to the sound is lower and the dynamic is greater.
But the price paid is increased costs. . .
