replacing the LV diodes did not make that sawtooth wave at that point any better, so i't most likely normal, I DO get the 1v wave, as shown in the Sams on the other side of L45, i'm 1/2 way through replacing the main filter caps.
I still need to clean all the POTs and the tuner, to try to get it to get some picture on the screen, however, I may just bypass the tuner and IF all together and tap in video at the 1st video amp, to save time, ( around L9 ) as shown below.
