Need help in understanding how this works.
In the attached schematic is shown the DC voltage measurements at top of C12 and C13 relative to “b” to be 11.46 volts and 5.4 volts. This means the current through R20 must be 0.0033 amps. However, this amperage through R18, the only DC source to ground suggests a voltage of 1100 DC volts which it cannot be. Just how are the voltages of 11.46 and 5.4 achieved?
