I have to disagree about always blaming caps. 90 % of the electrolytic
caps that I remove when a customer wants them all replaced are just
fine, unless they are near a heat source. SOME brands and series of
caps are suspect, but many are just fine.

Tim:

Likely the caps in this beast are Frako, even if re-branded. May as well write FlakO. So, at the very least they are suspect as you suggest. And if he has been running it off mains power, there may well be some heat involved.

Furthermore, this is a German Radio - meaning that Grundig never used one part where three-or-more would do better. Dealing with the caps - a necessary exercise in any case - may cure the problem. At worst, the effort is not wasted.
