I will develop schematics and pcbs for power amplifiers and pre amplifiers

This gig is perfect for Hi-Fi lovers. I work on circuits for microphones, power amplifiers, mixers, 4-band (or more) graphic equalizers, low-pass, high-pass, and band-pass filters, noise reduction, and full speaker setups including tweeters, woofers, mid-range, and subwoofers. I also handle active and passive filters, automatic gain control (AGC) circuits, and self-amplified speakers with treble and bass control for cars, professional music systems, and home audio.

Important: Converting values from decibels to volts, millivolts, watts, or milliwatts costs $70. Otherwise, please provide them already converted.
