Power Supply, Standby, Heaters, and Output Transformer
With wire cutters, cut the spade connectors off of the ends of all of the wires.
Strip the wire insulation off of ¼” of the end of the wire. Twist the end of the wire
and tin it with a hot soldering iron and a bit of solder.
Insert each wire lead into its respective solder pad location. Do not insert the
wire lead too far into the board. The wire may make contact the metal chassis
underneath.
Solder each wire lead to the board.
Here’s a representation of how to
install the wire lead.
Clean all solder connections with a
good quality solder flux remover.
Inspect the board for any solder that
may have splashed during this
procedure.
Fasten the ground wires from the Plexi SE PCB and the output transformer to the
star ground screw post.
Good Job!
You’re almost done. But, before you start celebrating, you still have to review
your work, start it up and test the voltages.
