I have this flickering, it seems to be less pronounced once the computer has warmed up. Searched the dead mac scrolls but there was bo exact match, what is your opinion?

Different machine, any thoughts on that?

Have you recapped the analog board yet?

I’ve seen that when I had a poor flyback anode connection to the CRT.

Not yet, I struggling to get my hands on the BU406D transistor and the 3.9t NP 100V H capacitor. I want to avoid working on the board twice.

Update. It was the flyback anode connection that was indeed the problem. Thanks!
