I am posting an update as I am back on to trying to fix my 465B.
I thought a working scope would help me troubleshoot a intermittent problem but I ended up not needing one.
I changed out the smoothing caps and all my voltages are now within spec and ripple is hard to detect.
Since my problem was intermittent I may have let myself be lead down the wrong path, very embarrassing. I had no trace, I pulled the W4032 jumper (HV Mult GND) and my trace came back. This lead me to believe the HV multiplier was bad. I swapped it out and my trace came back. I turned off the scope because I forgot to put the cover back on the hv multiplier and needed to remove the vert preamp board to do so. Once I got it all back together I had no trace and no -8v. Every time I had measured previously I had -8v but I am worried I changed out the HV multiplier without needing to do so.
Moving forward and using isolation, I determined the vertical output board was the culprit. I couldn't find any bad components so I re-seated all the transistors and the CRT vertical deflection driver and Voila! I had my traces back and cleaner than ever. I still have a problem with distorted square waves but fuzziness is gone.
I need to test my old HV multiplier to see if it is good or bad. Maybe I just bumped something on the Vert Ouput board when I was removing the CRT. Or perhaps this was the problem all along.
I need to figure out why square waves are so bad on both channels. it looks like excessive ringing.
