<VV> Factory AM/FM Radio volume comes and goes

[Stephen Upham]

I have a problem with the factory AM/FM radio that I need to solve  
before our H.O.T. meet in Glen Rose on the 18-20 of April.  We can  
use the FM to broadcast the drive-in movie that we are going to see  
as part of the activities during the weekend.  The radio keeps going  
on and off.  The problem seems to originate in the on/off-volume  
knob.  If I turn it on, the light on the dial comes on, but there may  
or may not be volume.  If left on, sometimes it will come on for a  
few seconds and then the volume goes off again.  If you turn the  
volume up, it sometimes blasts for a second or two and then silence.   
The knob is a little loose (comes out about 1/8 inch).  Sometimes,  
wiggling it gets the volume to come on for a second or two.  I  
checked the ground strap and it is secure.  Might this be an internal  
issue (bad, loose transistor), or will tightening the knob (and how  
is it done) remedy the situation?
