A view showing the gas-filled tubes that rectify the D.C. power for the ENIAC. The right-hand cabinet contains the power supplies for operating the test bench, a unit that is used for repairing and testing the plug-in chassis without interfering with the operation of the machine itself. Leo Clinton, maintenance electrician, is shown checking the operation of the thyratone, which can be seen glowing.
