Remembrances of vacuum tube days
As a young teenager, I developed a love for electronics which became a lifelong love affair. In those days vacuum tubes were the norm and solid state devices such as transistors weren't in usage then....

I remember an interesting part of the shift from tubes to transistors. The radio controlled model airplane receivers were vacuum tube models when I started. Miniature tubes, but still the receivers were pretty big.
The president of our model airplane club owned a hearing aid company. He arrived at one meeting with a hand launched glider that he flew around the meeting room that had rudder control. He had his engineers build a transistorized 27Mhz receiver that was about the same size as the rubber band actuator. Impressed the hell out of all of us.
