Pictured here is the Philips model 581A/15. Another large bakelite receiver, with enhanced short wave performance whereby many of the short wave bands are bandspread across the scale. This receiver would be from about 1951, but there seems to be comparatively few about. The circuit is a 4 valve plus rectifier design, and it was apparently being developed whilst awaiting the introduction of new and improved valve ranges since the chassis supports three different valve base types. As yet un-restored, further commentary to be added in due course.
