Boost voltage restored, I now know more than I did before.

I can almost get a pic locked in through the tuner, ( sound is OK ) pic is Horrid, and rolling horz. And there is NO COLOR via the tuner,( this may be partly due to the fact that i have 75 ohm hooked to 300, but unlikely ) this reflects the original problem with the set.
BUT if I tap in video at 1st video amp, I am able to get better sync lock and even some color lock ( a lot of barber polling)

This tells me the Original problem was most likely a messed up IF section.
I have not yet checked all the resistors in the IF yet,,, I stopped after I got a signal. I guess I have to check every one now.,,
but I'm not sure what I'll do w/o a known good Sweep Marker Generator...
