Philco's big 11-valve, 9 band radio with 5 bandspread bands. Full band coverage from 540kc to 22Mc. This model was available for several years and probably underwent several changes in that time, although the only service information appears to be dated 1945. It is largely equivalent to the US model 41-788 and subsequent variants, and further schematic changes and information might be found in US schematics. The 788 was finally replaced in around 1948 by the model 888.
