1967 RCA CTC-28 tube type TV repair part 2

Adding modifications for a relay to switch power and test panel for regulator and horizontal output current. The set now works but will need some more work on purity and touching up some adjustments.

I really enjoy your informative videos. I have a question. I have a RCA model G25189TK television. I'm using a multipurpose remote as the set didn't come with one. I can't change settings other than on/off, channel and voluem. The set swiks fine but I have to use the 75 ohm antenna lead for input. The set does have the 3 jack audio/video system, but I can't access it. Without it, I can't get stereo output. DO YOU HAVE ANY IDEAS HOW i CAN ACCESS THE JACK INPUTS? Suggestions would be appreciated.

@youthnotlost On some RCA sets the audio/video inputs can be accessed by tuning to channel 91.

This set looks very clean, do you work on sets from a smoker?

They are nasty inside.

@1112223333111 Also I blew out all of the dust with an air compressor, that can really help clean things up. Fortunately there did not look like there was nicotine and tar on this one.

@retrochad Thanks for the reply. My set only has channel up and down buttons. I can't get it to go up past channel 68. It then returns to channel 2. I have a satilite system so I don't use the tuner. It works on channel 3. I'd prefer to use my satilite box and DVD player through the direct inpus instead of the rf antenna. If you know of any other way to change the inputs, Please let me know. Thanks again for the suggestion.

I was thinking about making a joke about you getting a new tv also, being that this video was done a few days prior to black Friday, but see someone beat me to it. I mean the set is 43 yrs old. lol. It's all about a love for vintage though and we fellow vintage lovers understand. Great job on the repair and video, as usual. Thanks for posting it Chad.

@retrochad Yes, I know what you are talking about. This was the technology that inventors were trying to replace B&W with. Downside it wasn't compatible with B&W (when recorded in color) and it was very noisy and wasn't practical.

@xmaddict No, but I know about that system. What I'm talking about is using a colored plastic wheel with red, green and blue which spins in front of a black and white picture tube to produce a color picture. The Early Television museum in Columbus Ohio has a demonstration of this system and it really does produce good color.

@Lockemeister I don't watch all that much TV either but I really am interested in the technology of TV. We do watch DVD's of some of our favorite shows like Dallas and Star Trek Voyager.

@1112223333111 Yes I have worked on equipment from where there was a lot of cigarette smoke...the Leslie speaker amp was the most recent one. Everything was covered with a black film of nicotine and tar.
