Noisy Cricket Amp

Noisy Cricket Amp thumbnail
PCB design for Beavis Audio Research's Noisy Cricket Amp. Designed to be an onboard amp for an instrument with a speaker in the body. JFET buffer replaced with op-amp buffer from Jack Orman because JFETs are currently hard to find. LED is dimmer than the original because my eyes are sensitive. ☀️ http://beavisaudio.com/projects/noisycricket/ https://electrosmash.com/noisy-cricket-analysis
