This thing is gettin on toward applying for SS in electronics years & could 
have some ailments after 20 years.

Open it up Willard, and see if any of the small electrolytic caps have either 
leaked, or the tops are slightly bulged up.  Failing that, have somebody with 
a capacitance meter check and replace any that are down to half the label in 
capacitance.  The ideal however isn't the capacitance, its the ESR, but the 
cap meter will catch 60% of them.  For ESR, the gizmo is called a Capacitor 
Wizard, it gets them all.  Or just replace them all, they aren't that 
expensive, buck or so apiece.
