Circuit Schematic

The schematic (which is available in larger size jpeg, PostScript, PDF, or xfig, formats,) is a prototype circuit that implements the required frequency and crossfeed contouring. As a development objective, the low and high frequency contouring and crossfed control elements must not interact-they must be independently adjustable. (View)

Hi-Fi Headphone Amplifier
Can be directly connected to CD players, tuners and tape recorders. * Tested with several headphone models of different impedance: 32, 100, 245, 300, 600 & 2000 Ohm. * Old 8 Ohm impedance headphones can be also driven, but these obsolete devices are not recommended. * Schematic shows left channel and power supply (common to both channels). * Numbers in parentheses show IC1 right channel pin connections. * A correct grounding is very important to eliminate hum and ground loops. Connect to the same point the ground sides of J1, P1, C2, C3 & C4. Then connect separately the input and output grounds to the power supply ground. (View)
