To gain access for high voltage measurement, remove the red CRTs anodelead from the flyback transformer distributor. Grasp the anode lead protective cap at its bottom and squeeze itagainst thelocking cap body inside, rotate 1/4 turn counter clockwise and pull the anode lead sleeve out of the FBTdistributor. Connect a high voltage positive lead from your H.V. meter to the FBT distributor, and the common negative leadto cold groundFBT leads removalNote:Reinsert the anode lead into the FBT distributor until it is tightly and fully seated. Turn the locking cap clockwise to lockin place.(EHT) Protector operation checkWith the cabinet back removed, apply a nominal 120V A.C. to the PTV.Over voltage testPreparation:1. Turn PTV OFF2.
