Default CONNECTIONS, Screened 2.875-inch No. C1 ZA/CAN 4671

This is the shorter relative of its 5.5-inch cousin I covered in Post #617 and is of identical construction. In fact, it is the description of this CONNECTIONS, Screened that confirms how both are put together such that the wire does not make contact internally with the tube.

An appropriate length of the tinned, solid copper wire is cut and a small bead of solder applied at the required distance in from one end and a ceramic end cap dropped in place down the wire. Ceramic fish beads are then added down the wire in sufficient number to fill the metal tube. This wire and bead string is then slid into one end of the tube and pulled into place. The ceramic end cap is added to the open end of the string and a small bead of solder added at that end to secure and complete the assembly. The ceramic fish beads inside the tube are small enough let the wire down the middle of them flex with the curve of the tube, yet stay centred in the tube.

In the second photo of POST #619, you can see this CONNECTIONS, Screened tucked in between the two long rectangular banks of coil/caps, at the right hand side of the gap.
