They had a production of TV then, so I got all those defective parts and a picture tube, a scrap TV cabinet from the employee shop and put it all together. Now I had a TV set where every part was defective, it could probably have made the Guinness book of records, and it took me a long time to get it working, but eventually we had a beautiful black and white picture, and a pair of rabbit ears as antenna.
