The Luxy's cabinet design makes it difficult to tell from a photo that it's a shirt pocket radio, but it truly is, just about the same size as, for example, the Crown TR-666. It's also hard to imagine that this classic very-'50s-looking radio was produced around the same time as the gorgeous but quite '60s-looking Loewe Opta "Dandy". What a fabulous looking little radio this Luxy is! I love how its cabinet is reminiscent of much larger tube tabletop radios of an earlier era.
Unlike most 2-band LW/MW shirt pocket radios of the time, this set provided full coverage of the long wave broadcast band, 150 to 280 kHz, which was used a great deal in Europe in the 1950s and '60s. The Luxy's LW tuning scale is marked as kHz/10 ("15—30"). The MW scale is marked as kHz/100 ("5.2—16").
If you look at the chassis photo below, you'll note that three of the five visible transistors are mounted upside-down and packed tightly in the circuitry, making identifying them not worth pulling the chassis apart and possibly damaging it in the process. The two identifiable transistors are "right-side-up" large-can Valvo OC169s. The two diodes here are visible but their markings have been obscured. A Radiomuseum page gives several combinations for both the transistors and the diodes.
