Important Service Notes 1. X-ray Radiation Rrecaution Connect at 1500 ohm 10 watt resistor, paralleled by a 0.15 mfd. AC type 1) Excessive high voltage can produce potentially hazardous X-RAY RADIA- capacitor, between a known good earth ground (water pipe, conduit etc.) TION. To avoid such hazards, the high voltage must not be above the specified limit. The nominal value of the high voltage of this receiver is 25.5kv(20”/21”) & 23.
