Du Mont Electron Tubes Division utilized the fourth quarterly period to process and fabricate a second dummy F.O. tube and start the fabrication of a final, real F.O. tube of type KC2474P19. The second dummy was necessary to test an exhaust schedule cam which had to be fabricated in this quarter for bakeout of the final tubes. A potting fixture was designed and fabricated for potting the dummy and final tubes with RTV around the gold-foil frit seal. The cone and final assembly drawings were revised and up-dated at the start of this period. Author
