Glow on connecting wire

A glow on connecting wires can be sometimes spotted on some tubes. It is just an esthetical matter, it doesn’t harm the tube or mean any risks for it.

Practically every tube shows this phenomenon in first hours after manufacture, in most cases this goes off after first day of operation. In some cases, however, the glow can be present for weeks and rarely months. It will eventually go off completely.
