Hi Mark, does this Grundig have a a magic eye? If so does the display change under fault condition? A test of the EC92 could be, disconnect the aerial and connect a few feet of wire direct to the next stage (mixer grid) to see if the fault recurs. You could also unplug the EC92 during this test but a quick search for a Grundig 2012 shows a radio with a UC92, series heater.
