Often the speaker relay contacts develop intermittent connections on older
units. Try tapping on the speaker relay when the problem occurs and see if
that affects the problem.
Also try switching, turning and generally manipulating the various controls
and switches. One or more may be causing the trouble.
Excellent stuff. Also resolder the legs of any voltage regulator
IC's, as these tend to develope ring cracks with age (heat/cool
cycles).
In fact, get a really bright light and examine *all* PCB solder
joints. Can't hurt!
All the best fortune,
