shown. Be sure to position the transformer with the
blue leads toward the rear panel.
Refer to Pictorial 4-2 for the following steps.
NOTE: In the following steps, connect the capacitor leads as
closely as possible to the resistor body as shown in the inset
drawing. Solder the capacitor leads to the resistor leads and
cut off the excess capacitor leads.

NOTE: In the following steps, (NS) means not to solder
because other wires will be added later. “’S-’’ with a number
following it, such as (S-3), means to solder the connection.
The number following the “’S-’’ tells how many wires are at
the connection.
