Abstract:

Installation and operation information for time signal generator group QRC-37FT, as modified are presented. The original QRC-37FT power supply was operated from a dc power source of 23-29 volts. At 27.5 volts dc, the power requirement was 350 watts. The modified power supply will operate from an ac power source of 108-121 volts, 380-420 cps. At 115V ac, the power requirement is 143 watts. The 23-29 volt dc power source is still utilized for the operation of the crystal oven, time delay relay switch, and amplifier tube filaments. The dc power requirement is 100 watts at 27.5 volts. Mechanical changes are incorporated that result in a better layout of components and hardware. Author
