Huge. More of an explosion. Circuit boards were actually showing up in the 50's but there was still a lot of point to point wiring then too. Hybrids were showing up as tubes began to be replaced with solid state. By the 60's you never knew what you were going to find when you took the back off the TV and to work on them you had to know both tube theory and solid state theory. I know a few TV repair guys that threw in the towel because they refused to keep up. The "All American Five radios" in the mid 60's were tube circuit boards and I was lucky enough to be in charge of changing the bad tubes out around the house. I was hooked and never recovered! Dennis
