You're not really that far away from having things working well. While the picture looks a little dull (are you running the original 5TP4?), it looks like the RF is weak as well.
I ran into trouble with the RF AGC going to the tuner.
Take a look at the junction of R192, R167 and C175 coming off the plate of V106, the 6AT6 AGC amp. There is a wire going to the tuner from that point. If the value of the 2 resistors and C175 check good, try this: disconnect the wire from this point to the tuner, connect it to ground and see if that improves things. I don't know why, possibly due to a problem with the tuner, but I've worked on 2 of these, including mine that respond well to this change.
It's worth givin' a try and it ain't gonna hurt nothin'!
