MiniVCA 1.0
benjiaomodular/MiniVCA
A small footprint LM13700 VCA module for Eurorack modular synth

The BC559 is a bipolar made by onsemi in a TO-92-3 package with 3 pins. 1 PNP 100mA 110 150MHz 15nA 30V 500mW 5V 650mV PNP Standalone TO-92-3 Bipolar (BJT) ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BC559, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-92_Inline, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3201869). 29 open-source boards in 21 repositories on GitHub use it.
