    摘要： The present exemplary embodiments proposes a vacuum tube amplifier module which removes a noise caused by external shock or vibration, including a vacuum tube amplifier which includes an amplifier in a vacuum tube to increase an energy of an input signal to output the energy as an output signal, an assembly unit which fixes at least one side of the vacuum tube amplifier so as to primarily remove the noise, and a magnet which is assembled in the assembly unit to levitate the amplifier so as to secondarily remove the noise to make the noise a predetermined reference value or lower.

    摘要： A vacuum tube amplification system includes: a first power circuit electrically connected to utility power alternating voltage to transform it into a first DC voltage; a first vacuum tube amplification load circuit having a first grounding end, the first vacuum tube amplification load circuit using the first DC voltage as operating voltage; a second power circuit electrically connected to the utility power alternating voltage to transform it into a second DC voltage and output the second DC voltage; and a second vacuum tube amplification load circuit having a second grounding end, the second vacuum tube amplification load circuit using the second DC voltage as operating voltage. The first grounding end is not directly electrically connected to the second grounding end, the first grounding end and the second grounding end are each electrically connected to a compliance ground of the utility power alternating voltage through a jumper-wire zero-ohm resistor.

    摘要： A power amplifier to provide a compensated output voltage to a load through a series-connected impedance. The power amplifier includes an inner positive current feedback loop that is capable of sensing changes in the resistance of the load, and which adjusts the effective impedance of the series-connected impedance seen by the load to reduce current induced changes in the level of the compensated output voltage provided to the load due to the presence of the series connected impedance.
