very good manual with clear electrical schemes. Very helpful to find wat was wrong inside my microwave.

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

This was super service.Ordered this manual and was reading the download an hour later
;
as always, rapid and efficient, very good and clear prints
details clearly visible keep going this way!!!!!!
;
I expect a wonderful result as alaways!!!!!!
Usually is much faster....
