[Central-Electronics] Relay Question on Early CE Exciters

[Ron.K3PID]

Don't know if this will help but my schematic ( and actually on my 20A) has 
5 and 6 used to switch 115 vac to the socket on the rear panel which I use 
to run my antenna changeover relay.  pin 4 is not connected to anything. 
Pins 7,8,9 are wired to the rear terminal strip but not used in my setup. 
It is actually pretty easy to trace the connections from the relay if you 
need to be absolutely certain...

Subject: [Central-Electronics] Relay Question on Early CE Exciters

Gentlemen, I'm trying to get up and running, a very modified 10B exciter, 
and I plan to use it to drive a home brew grid driven pair of 4-400s that I 
did not build either.  I don't have enough relay contacts to make it all 
work.  I'm confused by the schematics and the socket on the later exciters 
which supplied 110V for an antenna relay.

My 10B schematic states that back panel contacts 8, 9, 10 (spare contacts) 
should be used for changer-over realy.  And contacts  4, 5, 6 for 
speaker/bias issues.  Yet that same schematic shows a set of relay contacts 
4, 5, 6 connected to nothing.

And my 20A schematic also shows contacts 4, 5, 6 duing speaker and bias 
duty, but this one shows a set of contacts 4, 5, 6 now supplying 110V relay 
voltage to a socket on the back panel.  Are there two sets of relay contacts 
numbered 4, 5, 6?  What am I missing here?

I need to fire up a 110V antenna relay with no extra contacts, and I need 
all the contacts I can get.

Thanks, Lynn (K5LYN).
