if you get finely matched capacitors
sorry, i dont understand what is finely matched capacitors are.
you could switch in a second capacitor in the vco
i guess it related some how to the finely matched capacitors?
can you explain a bit more please?
BTW i found the SH101 based sub osc, i stripboard it
suppose i will not take the output to q12 in the x0x and plug it in a VCA module.
