Are These Circuit Traces Bad

Well getting my brother over with his scope is proving to be a major task. I don't know when he'll have the time or desire.

I did manage to find NOS OEM transistors and the blanking diode. I also got my hands on the 1K, 33K and some 100K resistors, but I have a question about the 100Ks. The original 33K is a carbon composite (I believe from its shape and brown color case). The 100Ks look like standard film. I got my hands on the 33K replacement in the composite form. My question is about the 100Ks. I was given a few that are also composite, not film. Is it okay to use the composites as replacements? The wattage is the same. In the attached pics you can see the diode, 33K and two 100Ks in one and the 1K connected to the transistor in the other pic). Those are the ones I'm looking at changing.

So with the new transistor, diode and resistors I might just go ahead and replace them all. Of course this is after I replace the blue convergence coil that seized up. I managed to find an NOS replacement and it should be here Monday at the latest.
