Reminds me that I was once (during a Test Match series) very popular at school for having a home-brew 3-transistor MW/LW radio built into a Woolworth's plastic sandwich box. Reason for choice of box? - It had a circular vent grill exactly the right size to accomodate one of those DLR earphone transducers used as a speaker. Quite a group of boys could gather round and listen to scores etc. Also box could be installed between a couple of book covers and carried around with other volumes quite surreptitiously. Happy days! P.S. Transistors in those far-off days were sold to little boys by colour-spot designation -not numbers like OC71 etc -- 73 es gd dx de Pat G4GVW, Nr Felixstowe, East Coast, UK |
