7.1.3 Spade Connectors
Install the three male spade connectors as indicated. These are for the Output
Transformer (OT) leads. The Power Transformer (PT) high tension & heater
leads will be soldered directly to the PCB.
Extra solder time
is necessary to
heat the spade
connector before
solder will flow.
Hold the iron on
the connector.
Feed the solder
when the joint is
hot enough to
flow. Straighten
the connectors as
the solder joint
sets, or hardens.

Install the four (4) rectifier diodes.
Orient the diodes as indicated on the
circuit board.
Bend the leads over, insert them into
the board, and bend them to the side.
Solder them to the board.
Trim the leads off at the top of each
solder pool.
