CTC 28 Remote set Scored

[mbates14]

I would use a 80 or 120MM PC fan that runs at 12V, you can get 120v versions though.... and hide it inside the cage in a slotted area. that way its more "hidden"

regardless, that was an excellent thought on the fan idea there. keeps em cool

I have a couple of the small 2" IIRC square fans I was going to try, zip tied to the slots in the cage.

Glad to find this thread. I have brought my dad's CTC-28 back to my home town. It has been sitting in their basement for decades. It has bad a bad cataract condition on the CRT. But it is all there and I have the Sams for it. It is also the "Tonsberg" model as well. Was the first color TV that we had...

Glad you got one. They are great sets and fairly easy to work on. The cataract is easy to remove, Doug has some great videos on Youtube on cataract.

I would strongly not recommend cutting holes in the flyback cage as on the previous page. You completely loose all X-Ray protection exposing the contents of the cage

I use solid state 3A3's in the sets I have added fans to. I have to wonder how much danger there is with the regular 3A3 tube? I did take care when I cut the hole to have it where the tube still has metal around it. Only the transformer is exposed. When I did my CTC 38 I read on here there was none available and I checked around and found it to be true I have several hundred dollers in this set all new caps all new old stock tubes and a new old stock sylvania Black Matrix picture tube so I did not want to take a chance. I was lucky to find a new old stock fly on Ebay recently.

Thats neat your dad still has that set my parents traded theres in on a new RCA in 1978 I wanted it but I was about 10 and my dad said no since it did not work I was lucky to find one like it. Good luck with it they are nice sets.

Good point on the solid state 3A3, but there is still allot of high voltage potential around the fly I wouldnt want to expose. If you hold your finger up against the tire it will cook it. I tried this with a hot dog.

The flys are scarce but available if you look around. They can also be subbed fairly easily.

They usually fail near the top where the 3A3 stick in.

I saw some of those solid state 3A3s, ill have to grab one and give it a try. See if it reduces the heat any.

I don't know for sure but I always thought it was the tube putting off Xrays that was the reason for the cage. When solid state sets came out that had no High Voltage tube they also had no cage. The 3a3 tubes also have a warning printed on them that says tube may produce Xrays if not shielded.

Thats a good Idea.
