I have just added this new model to the collection. Before doing so I searched on the data base and by doing a tube search, with no result. I have been searching today on the web and have found that this set could be similar to the Mullard MAS231. I found the MAS231 on the Radiomuseum data base and they appear almost identical. This entry was submitted by Mario Huizinga. I have looked at his entry and on his website http://www.datastress.com/~mario/radio/types.php?group=600 and find these photos show two different radios. The pictures I have submitted come from an original Philips GB Service Manual so I think they should be the correct ones. I will gradually submit all the contents of the service manual, as time permits me. There are fifteen pages, plus a large pull out sheet of the full circuit diagram (schematic) and of the components layout.
My best regards to all
John C.
