Older Readers may remember it because it was used in the vertical deflection pattern of most tube TVs. Low Voltage Audio Amplifier ElectroSchematics Low voltage phenomena. Observe the low voltage gain of each stage, as indicated on the schematic. Voltage gain suffers at low voltages. The open loop Av is 190 total. Note that at normal voltages e.g. 6V, this degree of voltage gain can be accomplished with a single transistor. Impedance bridging In electronics, especially audio and sound recording, a high impedance bridging, voltage bridging, or simply bridging connection is one in which the load impedance is much larger than the source impedance. In cases where only the load impedance can be varied, maximizing the load impedance serves to both minimize the current drawn by the load and maximize the voltage signal across load.
