Pico Synth – VCO

Here comes the VCO.

This is in a temporary state, I haven’t put the 2k TEMPCO (any good sources to buy some ?) and the proper trimmers values (resistor instead). In this state, the range is around 500hz to 3.2khz or something like this, not great but the idea  is to validate or not the VCO and carry on the soldering if it is.

I’ll try to buy all the things needed at once, instead of multiple orders.

This main ramp core oscillator is based on Ray Wilson module :
