Summary
| Description |
English: This is a rare Philco "experimental" surface barrier transistor that is encapsulated in a sealed vacuum tube and was developed in early 1953. This item is in my private archive collection, that I had acquired from a former Philco engineer employee that worked at the Lansdale Tube company - Philco division. Philco had made its production models of the surface barrier transistor in late 1953, which were hermetically sealed in a small aluminum can. |
