I am the guy who made a deal to buy the CT-100 after no one bid on it. I could not afford to spend the opening bid amount, so I made a deal for a lower amount that was acceptable to the seller, and I picked up the set tonight.
Details:
-The front panel insert is not #472, but is #733, 753, or 793. It has had some holes drilled in its inside surface to make room for the shafts of some replacement pots that were added, and one of them is through part of the stamped number. Two of the original dual-shaft pots have been replaced by a total of four new pots, visible in a picture that I will post later.
-Some work was done on the HV section. A solid-state replacement was installed for the 3A3 rectifier; it later went bad and a tube was put in again. Another tube was replaced by a solid-state diode as well, apparently; I will investigate further. I will post a picture later.
-The set has a temporary back panel that is from a Zenith Service-Saver TV. Again, a picture will follow.
Here is my first try at inserting a picture. Please let me know if the size is appropriate.
