The murphy diagram dungeon
Murphy Radio only supplied service information to its authorised dealers. Consequently service manuals may be difficult for collectors to obtain. Eventually the firm had to relax this attitude; during the War there were few new radios to be bought, and many Murphy Dealers had been called up for National Service. Therefore the most popular Murphy sets were submitted to 'The Wireless & Electrical Trader' magazine for inclusion in their ever popular 'Trader Sheets'. These are an invaluable source of service information for many, many radios and televisions. If you would like a set of 'Trader Sheets' why not join the British Vintage Wireless Society? As a part of your membership you will get two CDROMs containing the Trader Sheets in handy electronic form. It's worth joining for this alone! Right, that's the end of the advertisement...
The object of the Diagram Dungeon is to publish as many Murphy circuit diagrams (and eventually, full service information) as I can obtain.

The information is indexed according to year and model number. If you know the year of manufacture (or think you do) then go straight for that. If not there is a second list of model numbers (in vaguely numerical order). If you just want to browse and look at the pretty pictures (there's a thumbnail of each set) start at the 30s and work your way along…
