Certainly check the power supply first.  You likely have aging 
electrolytic capacitors which may be in stages of first breaking down. 
If the supply is also 1998 vintage, likely the electrolytics are on 
borrowed time.
Once you have substituted a known good supply, and still have a problem 
check by passes of electrolytics in the radio around the stage where the 
symptom is caused.
Do try a different and good power source first to isolate the problem to 
the radio or the power supply.
