Thanks Bruce,
>From what I understand though, is that the Vibrator in the PE-104 unit a
Radiart VS-3 is configured differently from the DY-88 and would need to
wired differently. In the SCR284 radio sets they can only be operated by 6
or 12 volts, selectable by a switch on top of the PE-104 Power Unit
