The bases are pre-glued and readied for the insertion of the leads. This process forms the base / envelope shape we all know.

The wire leads from the tube are inserted into the pre-glued base and the tube is placed into the basing oven where the envelope and base are permanently joined.

Solder is applied to the pins to make the electrical connections secure.

The tube is now complete. The last step, before the electrical tests, is the final visual inspection. A long-time Western Electric employee performs this inspection. If there are any visual faults at all, the tube is rejected.
