If you know CT-100's, you'll know that it's ALWAYS more than one bad peaking coil.

Yes, mine had numerous bad peaking coils. But its not likely that a restored
set that worked a long time after restoration would lose more than one more at a time. This particular failure is more likely something else. |

I had 12 pictures on EBay and all but 2 disappeared so I ended the auction and will resist when I get home from Japan on Tuesday. stay tuned.

Why does something as historically significant as the CT100 have to be restored to working by replacing factory original parts? I have no problem restoring other less rare and or otherwise abundant examples. I was just looking at Phil's CT100 page, all loaded up with imported modern parts. Originality is gone.

Many of the older original parts were subject to decaying because of materials
used, drying in the case of capacitors, heat damage and drifting values in the case of resistors, and insulator break down for coils, dielectric material that did not stand up to the voltages used.... In a lot of cases also once a minor part went bad, it could cause over current conditions to burn out transformers, that are not available to replace at any price.... Replacing a lot of those parts is just buying insurance. Insurance that the older part might be ready to go- and that the new part chosen may be of at least good enough quality that for the immediate future, the chance of failure, and taking out a more expensive, and hard to find part may not happen..... Like a flyback, yoke, etc.... There is also the argument to be made that the set will work better if all the parts are brought back to their designed values. Tolerances of some non critical parts were often specified to be 20%, quite a bit off designed value..... And over time they drifted even more..... Doing so for every part means you have to re-align all the circuits to achieve the goal of a better working set... There are a few people here that have done all the work required, and have been rewarded with a set that can be run for hours at a time, and years of use without having to fiddle with all the knobs with each use, and rolling picture after a few hours, and constant retuning over the hours of use.... But really good parts have to be used..... Any you have to be careful, or you end up with more trouble than if you just fixed the original problem and used it on the old parts..... .

We shall see what the Reitan CT-100 with working CRT sells for. The
reserve is a great deal ... but it won't sell for that. When I restored mine, the aim was a perfectly working set. I did not restuff parts. But I DID save all the originals. If someone in the future wants the original look, they can do the restuffing. The white peaking coils would have to be replaced with modern ones inside a fake shell, not hard to do. |

Someone may want to reinstall the original parts without restuffing. At some point it will not be important whether it works or not. What may eventually become important is the original parts with mfgr. names and date codes are present.

That's a minority viewpoint among collectors, even of the rarest of rare sets--which frankly the CT-100 is not. Extremely desirable, but not extremely rare. TV sets in their truest original sense are appliances that must function to be of any value whatsoever. So it is a trade-off no matter which side you come down on. And I come down on the side that maintains originality as much as is practically possible in restoring the sets to work. And from a practical standpoint, a CT-100 is a far more impressive thing to demonstrate than to merely display.
