ANODE LEAD REMOVAL
To prevent damage, the following procedure must be used when removing an
Anode Lead from the Flyback Transformer.
3) Carefully remove the Anode Lead
from the Flyback Transformer.

CRT REPLACEMENT

High voltage should be completely discharged prior to CRT removal.
Since the CRTs receive high voltage from the Flyback transformer, discharge the CRTs
by shorting the open end of the respective high voltage cable to chassis ground.
2) While holding the lead down rotate
the lead 90º counter clockwise.
