Four "fleaw clips have been included to facilitate power supply cormeetion.
hsert these
clips in the holes at the end Of the circuit board marked "++". "+ ", ''-" and " i ''.
Solder in phee.
In the following steps wires will be soldered to the ''8" circuit board which will later comect with
front panel controls and jacks. At each step strip 1/4 inch of insulation from each end and twist
and ''tin" the exposed BtrandB.
UBing the wire provided make the following connections to the circuit board.
