The Keyall: Insulating the output jack

In the KI6SN version of the Keyall, a large hole was cut in the front panel of the unit's chassis. This gives adequate clearance for the RCA output jack to "float" above ground on a piece of plastic that was then bolted to the inside of the front panel. Insulating the output jack from ground allows the Keyall to be used with non-grounded key lines. For a close-up view, doubleclick the photograph.
