# Noisy Cricket Amp ## Description 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 ## Project Details - **Owner:** jwwitherspoon - **Created:** 3/21/2024 - **Last Updated:** 4/12/2025 - **Visibility:** Public - **Stars:** 1 - **Copies:** 1 ## Key Components ### D1 — [LED THT](https://www.flux.ai/jharwinbarrozo/led-tht.md) - Emission Coefficient: 3.73 - Series Resistance: 0.42Ω - Forward Voltage: 1.70 - Saturation Current: 93.2e-12A - Breakdown Voltage: 0V **Pins:** - A [pin 2] - K [pin 1] ### J1 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/pin-header-01x02-254mm-vertical.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - P1 [pin 1] - P2 [pin 2] ### J2 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/pin-header-01x02-254mm-vertical.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### J3 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/pin-header-01x02-254mm-vertical.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### SW1 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/pin-header-01x02-254mm-vertical.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - P1 [pin 1] - P2 [pin 2] ### SW2 — [Pin Header 01x02 2.54mm Vertical](https://www.flux.ai/jharwinbarrozo/pin-header-01x02-254mm-vertical.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - P1 [pin 1] - P2 [pin 2] ### U2 — [LM386](https://www.flux.ai/miguelm/lm386.md) **Pins:** - Bypass [pin 7] - G1 [pin 1] - G8 [pin 8] - GND [pin 4] - In- [pin 2] - In+ [pin 3] - Vout [pin 5] - Vs [pin 6] ### U3 — [TL071CP](https://www.flux.ai/jwwitherspoon/tl071cp.md) - Part Type: Operational Amplifier (OP-AMP) - License: https://creativecommons.org/licenses/by/4.0/ - Manufacturer Part Number: TL071CP - Datasheet URL: https://www.ti.com/lit/ds/symlink/tl071.pdf - Manufacturer Name: Texas Instruments **Pins:** - IN- [pin 2] - IN+ [pin 3] - NC [pin 8] - OFFSET N1 [pin 1] - OFFSET N2 [pin 5] - OUT [pin 6] - VCC- [pin 4] - VCC+ [pin 7] ### VR1 — [Pin Socket 01x03 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x03-254mm-vertical.md) - License: https://creativecommons.org/licenses/by/4.0/ - Part Type: Connector **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] ### VR2 — [Pin Socket 01x03 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x03-254mm-vertical.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] ### VR3 — [Pin Socket 01x03 2.54mm Vertical](https://www.flux.ai/adrian95/pin-socket-01x03-254mm-vertical.md) - Part Type: Connector - License: https://creativecommons.org/licenses/by/4.0/ **Pins:** - Pin_1 [pin 1] - Pin_2 [pin 2] - Pin_3 [pin 3] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/jwwitherspoon/noisy-cricket-amp](https://www.flux.ai/jwwitherspoon/noisy-cricket-amp).* --- *Generated from [https://www.flux.ai/jwwitherspoon/noisy-cricket-amp](https://www.flux.ai/jwwitherspoon/noisy-cricket-amp)*
