[Johnson] Rear 120VAC Connector on Johnson Transmitter

[Greg Mijal]

Hmmmm.....Nope!
Perhaps you could pull out the HC/6 holder and put in a FT 243 style holder 
then modify a dead FT 243 crystal to accept the ac wires.
One of the hard things about trying to make a connector from a HC/6 crystal 
is alot of them will not take solder.
So it's back to the "why did they do it that way" for the Johnson relay 
power connector.  Same as the:" Why did National energize the TR relay for 
the NCX 5 in receive and not in transmit?"
Only the Shadow knows!
