#93321 - never coils in power return Responding to: ???'s previous message |
there are two colis L1 and L2 in series with input of 7805 to avoid common mode and diffrential noise
That will kill you. The coil in the ground return will make the whole darn thing jump effectively making the reservoir cap isolated from your circuit. Do not mistake differential circuitry and power supply. Erik. |
