Mount the ring core transformers:
Stick a adhesive foot to the base of the cabinet, in the middle where each transformer has to be put.
Mount an output transformer on the left-hand side of the housing, see figure 6.0.
Check the position of the leads.
Turn over the housing and solder the trans-
former leads to the output terminals, see
figure 7.0.
Do not forget to insert a 3 cm length of insulating heat shrink sleeve over the wires:
Solder the double yellow wire to the 4 Ohm loudspeaker terminal.
Solder the red wire to the 0 loudspeaker terminal.
Solder the blue wire to the 8 Ohm loudspeaker terminal.
IMPORTANT: Heat the terminals up until the solder melts easily. Then slide the insulating heat
shrink sleeve over the leads.
