Some of those mica caps are dependent on the casing to keep the capacitance @ a fixed value. If it's cracked I'd replace it.
I fixed up an 18T a while back. https://www.flickr.com/photos/42774321@N08/4508825569/ The spkr isn't so hot but set plays well.
I don't think the 18T has a bias cell. Did have rubber wire best I remember.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
