Hi, thankyou for providing the Nordmende Globetrotter original manufacturer's repair manual. Quality is very good and sharp - the PDF file was comfortably small to download. The only question is: why did it take so long to become ready for download?? Many thanks anyway, I fixed the fault in the radio thanks to the circuit.
regards: Nick
