pins need to be soldered). Properly determine the positions of the soldering pads and pins by
correctly aligning the polarity symbol
5. Solder all pins to the soldering pads using a fine tipped soldering iron
6. Check with a magnifier for solder bridge between the pins or for dry joint between pins and
soldering pads. To remove a solder bridge, use a de solder braid as shown in the figure below
IMPORTANT
To protect against possible damage to the solid state devices due to arching or static discharge, make
certain that all ground wires and CRT DAG wire are securely connected.
CAUTION
The power supply circuit is above earth ground and the chassis cannot be polarized. Use an isolation
transformer when servicing the receiver to avoid damage to the test equipment or to the chassis.
