Lawrence you're a Gent.

I'm one of those folk who has to know why even when you've sorted the problem so please see the attached photo.
Pin 3 of the Valve base is broken and obviously wasn't making good contact/any contact. So the Cathode wasn't being Grounded as you suspected.
New Valve Base and the EM87 is working fine.
LEAK only recommend it's use during tuning, once the desired Station is found, the AFC should be turned ON which turns OFF the EM87 during listening. But it's good to have everything working.

Many thanks,

James.
