This circuit allows you to adjust the balance between channels of a stereo amplifier. The circuit makes use of an analog indicator with zero in the center of the scale.
The frequency of this oscillator depends on the crystal used. The transistors are general purpose. We...
You can measure capacitances across a large range of values using the AC Power line frequency as...
The circuit of the figure serves the same purpose as the previous one (CB5057E), but has a...
