In 
the following step you  will  install knobs 
on 
the two control 
shafts. Perform this step carefully, since it is difficult to remove 
a bushing from a knob  once it 
is 
fully inserted. 
(  )   Install knobs on each of the control shafts as shown in 
the Pictorial. 
This completes 
the 
wiring 
of 
your 
Transistor Tester.  Proceed 
to 
"Test 
and 
Adjustment."
