Re: Britannia B1014R - Fidelity chassis
Not seen one of these for years! It's an odd fault, certainly. A scope will be invaluable here to have a look at the signal exiting the TDA4503 to see if it increases in amplitude as the volume control is adjusted. I have a vague recollection of the 10 ohm feed resistor to the output stage going open circuit but that's all I can remember - these were pretty good basic TVs.
