Step #7 – Input Transformer (T1)
IMPORTANT - TRANSFORMERS ARE POLARIZED AND MUST BE INSTALLED IN THE PROPER
ORIENTATION.
Position T1 on the PCB noting the proper transformer polarity.
(Figure 15)
Solder all three mounting pads on T1 for proper attachment to PCB.
(Figure 15)
Strip the insulation from one end of the 6” orange #22 wire. Solder the stripped end to one
PRIMARY pad.
(Figure 15)
Wind the unsoldered end of the wire four complete turns through the tubes of the transformer in a
loop type fashion.
Cut and strip the wire, making it just long enough to reach to the remaining PRIMARY pad.
(Figure
15)
Solder the wire to the remaining PRIMARY pad.
(Figure 15)
Strip the insulation from one end of the 12” orange #22 wire. Solder the stripped end to one
SECONDARY pad.
(Figure 15)
Wind the unsoldered end of the wire two complete turns through the tubes of the transformer in a
loop type fashion.
Cut and strip the wire, making it just long enough to reach to the remaining SECONDARY pad.
(Figure 15)
Solder the wire to the remaining SECONDARY pad.
