The 360 uses as standard 3WP 3-inch (7.5cm) round CRT. The cathode voltage is -1850 volts. No post-deflection acceleration is used. | The 360 uses as standard 3WP 3-inch (7.5cm) round CRT. The cathode voltage is -1850 volts. No post-deflection acceleration is used. | ||
The 160 power supply was produced with serial numbers 101-619. For serial numbers 620 and up, it is called the 160A. The 160 and 160A both use a [[5V4]] rectifier tube for the negative voltage and two 5V4 tubes in parallel for the positive voltage. Both use [[5651]] 87-volt reference tubes. | The 160 power supply was produced with serial numbers 101-619. For serial numbers 620 and up, it is called the 160A. The 160 and 160A both use a [[5V4]] rectifier tube for the negative voltage and two 5V4 tubes in parallel for the positive voltage. Both use [[5651]] 87-volt reference tubes. The 160 and 160A differ in their output regulator circuits. The 160 uses [[6AS7]] dual-triode tube, one half for to regulate the +225V output and the other half to regulate the -170V output. The 160A uses both halves of a [[6080]] dual-triode in parallel to regulate the +225V output, and both halves of a [[12B4]] dual-triode to regulate the -170V output. | ||
