How to repair Heathkit IO-4510 Oscilloscope Vertical Channel Part 2

Part 2 of the Heathkit oscilloscope restoration. In this video, I will troubleshoot and repair Channel 1 vertical input circuit. This is a vintage piece of test equipment. Back in the day, I would kill for one of these scopes. Now you can find them for peanuts. In a way, I like that, but in another, it makes me sad for the Heath company. What a great point in history. Plus, what a loss for our culture. Heathkit was not just about selling kits, however promoting a culture of common sense electronics. They were my elmer's. I followed their direction, formed me to the technician I am today. My goal was to be the goto electronics guy. They made it happen. I wish that I could go back in time, work at HEATHKIT!
