The tripper pulse is produced by a snap diode. | |||
Air gap capacitors couple the tripper pulse to the tunnel diode. | |||
These capacitors, C185 and C186, are drawn with dashed lines in the schematic | |||
because they are really just stray capacitances. | |||
One side of each capacitor is the unconnected center pin of the bulkhead-mount female | |||
[[Connectors#SMB|SMB connectors]] in the side of the airline. The other side of the | |||
capacitor is the conductive tunnel diode mount in the core of the airline. | |||
