Let's do a deep dive into some of the circuits, analyze some of the problems and look at some of the fixes. We do a review of the video amplifier and the frequency / phase equalizing circuit. BTW, I lifted that circuit, lock stock and barrel, right from the original 1950 RCA manual for the TK-1B monoscope camera manual. Moved it straight from a vacuum tube circuit and placed it in a modern op amp circuit. Low and behold, it worked!
Second, we examine the electron gun blanking circuit in the monoscope tube. I prove that circuit is working correctly beyond the shadow of a doubt.
Lastly, we wrap it all up with how I repaired the horizontal scan retrace issues. (I hope. You know how these things can go!)
Enjoy!
