HP-23A

[Glen Zook]

The "off on" switch in the Heathkit transceivers
shorts across these pins to turn the power supply off
and on.  You do have to have the switch on the supply
itself in the "on" position as well.

Looking at the schematic, it appears that only one
side of the primary winding on the transformer is
connected to one side of the 120VAC in. The other side
of the primary winding goes to pin 9 on the output
connector and the otherside of the 120VAC goes to pin
10 on the connector.  How does the primary get input
that way?
