==Internals== | |||
The 514 uses a [[5CPA]] CRT with a total accelerating voltage of 3 kV (−1.5 kV on the CRT cathode and +1.5 kV on the CRT anode). | |||
The standard [[phosphor]] for a 514 was P1. | |||
The deflection sensitivity of the CRT is approximately 27 V/cm vertical and 32 V/cm horizontal. | |||
The power supply is regulated based on a −140 V reference produced by an [[OD3]] gas regulator tube. | |||
The +225 V supply uses three [[5V4G]] rectifier tubes in parallel. | |||
