Are These Circuit Traces Bad

They are quite often the bad boards. Someone changes it &
never marks it as bad. Many shops were careless about
returning duds for core credit, often loosing track of where they
came from etc. No invoice -no credit.......
Also many put them aside to rebuild themself "when a chassis
comes in & I got time" Needless to say that usually was never &
bad boards piled up. Then someone comes along 30 years
later & liquidates them on E-Bay. No way in hell he knows.

I quite agree - when my dad retired back in 2008, he had exactly 7 good Zenith Duramodules and about 30 boxes marked with the symptoms the module had. After the heyday, and after junking a few sets, shops ended up with lots of questionable stuff.

As far as needing a transistor, post the 121- number, as many of us have stashes of original parts - yours for postage, in my case. Don't default to buying new stuff when we might have what you need, and are willing to give it away!
