All respect due, that is just as you said- an assumption. Just because it's free of PVA deterioration is NOT proof of other chassis parts replacement. I had an original Zenith tube in my closet that had no cats... The lighter color may just be because of the way the photo was taken, and it wasn't a very good shot to begin with. Also remember that not all brands used the same material to attach the lens, and there's no promise they all transmit the same amount of ambient light. Ones with frosted lenses will look different still.

That fact along with the wrong knob and color controls that have been cleaned wrong erasing the pretty colors indicate the set was used alot and therefore had repairs.

Again, conjecture. Proof of use is not proof of repairs. Just because a set has a lot of hours doesn't mean it had repairs, I've seen plenty of sets go all the way on all original parts.

It is almost a certanty that the flyback was changed for it to last long enough to need a CRT.

What do you base this wild claim on? Again, I have seen many sets with a lot of hours and original transformers. My own CTC-4 has a lot of hours on it, and aside from a flyback that RCA themselves changed (apparently due to a manufacture's update part, not failure as evidenced by the hang tags left by the techs), the chassis was all original when I picked it up from the original owner's home in Indiana. The CRT in it had been replaced at least 3 times, which can be seen by the glass welds on the picture tube. So by your logic, it has had at least 2 flybacks replaced right?

So, doesn't matter the circuit boards may be baked. You are likely to get a god CRT, Flyback, Yoke, correct wood veneer to repair cabinets and many other small parts, maybe even a good transformer. Then you are stocked to maintain or rebuild another and just throw away all you dont want like the cabinet faceplate, etc.

High hour sets do tend to have baked PCB's, but again, we can't see the back of the set. Mark's CTC-9 had some good hours on it, ask him what condition the chassis parts were in when he started...


I not saying this to be a jerk or anything, but there are some wild claims being made here. I know I'm not alone when I say that not all of these old sets were 'bad' with respect to maintenance, in fact some of them went a lot of years between servicing and never needed parts. My CTC-7 still has the original flyback, and has had at least one CRT replacement during it's lifetime...
