Hello after doing the little angel chorus, I thought of making one, also using the PT2399, but with a sinusaidal wave generator on the LFO. The result was this, a warm chorus on a PCB no longer easy to do and with very few components.
NOTES:
* depth control can be 250k or 500k, the higher value, the lower the effect attack.
* R19 is the resistance responsible for controlling the delay time of chorus, you can put a 5k potentiometer in series with R19 to have a time control.
* Speed control depends on C1, C2, C3 and R2. Enlarging the three capacitor or the resistance we can get slower repetitions, achieved in configuration C1 = C2 = C3 = 470nf and R2 = 100k have a balance between fast and low speeds.
* 78L05 voltage regulator is invested in the circuit because it had not as a component in the libraries of the eagle, but is the correct posisicion Layout.
