Version 8.2 of the Common Emitter/Collector Amplifier Board is public

– It’s about making experimentation easier –

Version 8.2 adds several refinements:

* Breadboard-friendly input and output pin header footprints

* Breadboard power connection footprints on both the input and output sides

* Optional jumper locations for greater configuration flexibility

* A dedicated staging area for temporarily mounting trimmers using female pin sockets during circuit tuning

* Increased spacing in several areas to make assembly and soldering easier

The board is intended as an educational experimentation platform rather than a finished amplifier design. Every footprint is there to encourage curiosity, testing, and learning – not just building one predefined circuit.

The layout guide is already available. – Explaining the reasoning behind the different sections of the PCB and how they can be used for various amplifier and oscillator configurations. – Find it here:
