[time-nuts] HP 58516A GPS antenna distribution amp.

I was donated one of these recently that has an unuseable output 
port-port three. I've not checked its operation yet but wondered if 
anyone else has had one of these with a similar problem. From a brief 
look inside it's hard to see what could go wrong on 'one port only' so 
I'm hopeful its something simple and obvious.(and easily fixed!)
