Still unable to to preform Color AFC Setup.
Only able to see barber pole effect. ( still may be IF related, unknown )
BW pic is very stable.
Cathode v on burst amp is now at 40v, where it should be, but seeing a 10v saw tooth wave there, not sure if this is normal.
Not finished going over PCB for other errors yet..
evidence that L24 ( bandpass coil ) may have been replaced.
STILL getting no scopeable video on the far ( badpass ) side of C22, it also looks to have been replaced. Removing v17, killer / chroma bandpass tube makes no change in this, but lifting the far side of the cap does.
This situation was first spotted years ago when I got the set.
Will have to try and dig deeper ( find other errors ) to work out why it's dong this,
From what I understand, and how this all works, if NOTHING is getting past C22, or its getting distorted somehow, there is nothing for the Burst amp and bandpass to work with, and thus the color osc can't lock on and so on...
I should see SOMETHING on both sides of C22, right?
