10 11F electrolytic . Be sure to match
the positive ( +) mark on the
capacitor with the positive (+) mark
on the circuit board .
NOTE: Install the following transistors in
the manner shown . First line up the flat of
the transistor with the outline of the flat
on the circuit board. Then insert the
transistor leads into their correct holes,
which are indicated by E, C, and B. Solder
each lead to the foil and cut off the ex cess
lead lengths.
