The cap w/the coil around it is to help block out long wave stations from being amplified in the IF stage and causing interference. LW activity is pretty low theses days so interference isn't a problem. Short answer is you need the cap but not the coil. If you want to keep it original looking you can restuff the old cap and keep the coil.
Loktal tubes can be a little problematic as the steel pins get oxidized and cause a intermittent or bad connection. It's good practice to clean the pins w/some Deoxit and plug it in and out of the socket a few times. Some lock in really well and are difficult to remove, a very small amount of grease to the index pin in the center works for me. They can really be a pita in portable because of the lower voltages and hi impedance.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
