Thanks Very much for the assistance JANA, I fix 30's and 40's tube radios as a hobby, well, hobby gone wild :) So I am pretty well useless with IC electronics, but not frightened by replacing or substituting caps, and re-wetting the solder joints. I will try this , but perhaps I should wait till it starts to happen more often so I can see right away when if I nail the problem down.
I wish I has one of those ESR meters. I really should, most of the stuff I work on is 50 to 70 years old so I use the shotgun approach more often than not. I have a heathkit checker with an eye tube.
..I didn't understand the reverend's acronym.... the e-w circut , that went over my head.
