Terry, I don't see a resistor or capacitor going to the O-coil. But pin #4 of the 36 goes to pin 1 of the O-coil. From that point, I get nothing- open on the other 4 pins. . I get 8.5 Ohms from the top cap 36 to gnd. O-coil OPEN?

If the noise is still there, the OPT might just be OK. Or so we hope.morzh — 12:01 PM
