About the Finals-Transistor PCB
Finals-Transistor is an open source PCB design by kholia, published on GitHub under the Custom license license. It is a 2-layer board measuring 57.9 × 38.4 mm, with 13 components from 11 distinct parts.
By type, the board carries 6 capacitors, 1 transistor, 1 test point, 1 diode and 1 inductor.
It belongs with the audio designs in this gallery.
From the project
RF "Lego" blocks. Quite-Linear HF broadband RF amplifier experiments for higher bands.
The Finals-RD15.kicadpcb` is oversized on purpose for two reasons:
- To avoid the tedious job of cutting the larger 3x2 PCB into a smaller size.
- To save etchant by putting a copper pour over the larger area.
