Designed a complete circuit replacement for an open reel tape deck, excluding the bias oscillator. Included 4 position EQ, simultaneous encode/decode companding noise reduction (based on dbx II curves using the Signetics NE572 compander), variable bias, meter drive, power supply, headphone amplifier, and output buffers. Schematics were later input into OrCAD.
The schematics for the tape deck are available in PDF format by clicking the thumbnail above.
