- Pb free solder will tend to splash when heated too high (about 1100
°F or 600 °C). / If you must use Pb solder, please completely
remove all of the Pb free solder on the pins or solder area before
applying Pb solder. If thisis not practical, be sure to heat the Pb
free solder until it melts, before applying Pb solder.
- After applying PbF solder to double layered boards, please check
the component side for excess solder which may flow onto the
opposite side.

The anode caps are cemented to the CRTs. To gain access for high voltage measurement,
remove the red CRT's anode lead from the flyback transformer distributor. Grasp the anode lead
protective cap at its bottom and squeeze it against thelocking cap body inside, rotate 1/4 turn
counter clockwise and pull the anode lead sleeve out of the FBT distributor. Connect a high
voltage positive lead from your H.V. meter to the FBT distributor, and the common negative lead
