So, I'm still kind of wondering, should I even try to keep working on the IF section given the following...

When I got the set, there had been extensive work on the color PCB for a no color problem.
98% of all non power resistors were replaced, 5% of the caps replaced, and the bandpass coils.
Not to mention,it seemed the entire color PCB had been removed.

Upon going over the work done, I found several quality issues, including 4 resistors of wrong value, 1 cap with a lead open ( hanging), poor solder work and an issue with the color osc coil.

The most disturbing thing noticed is, the shield cover on the IF section was missing, but the bottom was on.
I could not see that any work was done in the IF, but chances are high that coils may have been messed with. (no way to know)

In the years of storage , the IF stopped working completely.
While testing , it was discovered that I could get color through via video injection at 1st video amp.

When checking resistors in IF section, found 2 that were open and about 2 out of tolerance, and the rest were just within tolerance.
After replacing the bad ones, I was able to use the tuner to lock in and get a good clear picture and sound, but w/o color.

And as mentioned earlier in the forum, I then focused on getting color working via video injection.

So, I am wondering this, 85% of the resistors in the IF section are still original that checked “ just within tolerance” but given the fact that chances are good that the coils may have been messed with, is it even worth the effort to replace the rest, given the state now that when I do try to use it I get a good stable b/w video and sound, would there be anything to gain in trying?
Or could it make it worse?
I have no idea.
