I have cleaned up the power supplies with new caps all around. Still have a horizontal jitter. Its almost unnoticeable during A sweep. Its most noticeable in delayed B starts after delay and inten A, it almost stops when I switch to Norm. I can see the leading and edge and the end of the sweep waveform inching/bouncing up and down like the level is being adjusted rapidly. It also happens in X-Y mode when feeding it an out of phase sine wave most noticeable in 10X mag the lissajous pattern will jerk horizontally. Occasionally when turning the delay time position pot in inten A the highlighted section will move further than what it should and come back on its own to the correct position. By this occurring in X-Y mode can totally eliminate anything to do with sweep? All electrolytic caps have been replaced and any tantalum that was replaced was replaced with a matching tantalum. I dont want to just start removing zeners and stuff , too easy for me to mess things up. Any ideas? Thanks guys.
