Looking at the pictures in posts 1 and 5, I'd say the connections should be:-

Top row of tags.

2nd from right BASE. Centre lead or apex of triangle. Note potential divider and coupling capacitor.
3rd from right COLLECTOR. Note the red spot.

Bottom row of tags.

2nd from right EMITTER.

I agree that those Plessey caps are unreliable and should be replaced in the long run.

However that's no reason not to make sure the replacement OC71 is fitted correctly and take a few voltage readings. A battery player isn't going to kill you.
