Woo hoo, the CTC-21 is up and running. :banana:

Such a sweet old girl....and I am freaking bouncing off the walls. She is ready for the Holidays and for the switch over.

The pics are from a dvd and not the clearest in the world as I didn't have my pro slr camera, just a little point and shoot but you can get the idea and see her working in all her New Vista glory! :yes:

Still have some touch ups to do on the convergence and I still have a couple of caps to replace and I will probably go ahead and replace a e-cap can that seems to be a little warmer than I would like, but otherwise, she is up and running.

She had lost all color sync, vertical linearity and the usual chroma board ground issues. The flyback seems to be running quite cool....just lightly warm after 30 minutes of operation and this is a good thing for sure.

Thanks for the kind words everyone.

I am pretty thrilled at it. I will try to get a better photo with my pro camera. Still have some more work to do on it but it is pretty much there. I have already restored the amp/tuner unit and still need to replace the caps on the speakers and the power supply for the stereo. But everthing works well at this point and for me, that is a big accomplishment.

This is my childhood set, my folks purchased it for $1150 back in September 1967, the month before I was born. All of my childhood tv life was spent in front of this set until we retired it in 1982 as most tv repairmen wouldn't touch it and it had developed some problems. I was not competent enough at the time to dive into it and repair it. I replaced the CRT and yoke about 20 years ago but I know there is less than 20 hours on that CRT so it is still basically new and have been nursing it along. But now that it is close to having been restored, yes there were a few paper caps and one black beauty...sheesh, they just had to stick that one in there....it has come a long way.

As soon as I am done with the touch ups, the CTC-47 goes on the bench to see what the heck fried under that chassis to cause the HV loss.

I just love these old tvs. :yes:

I love 'em too! I don't see how a person couldn't. That is so freakin' cool that it is your childhood set. There must be an amazing amount of memories attached to it. I wish my childhood set was this cool. We had an '81 "sears" set with a three button electronic ultrasonic remote. The remote quit working in about '90, I fixed it but it only lasted another year. The set died in about '95, had billions of hours on it and the CRT went dead, I threw it in a dumpster after kicking in the front.

Progress
Sulu is gay, Shatner is a wife drowner and horse lover, Scotty died in a wheelchair after fathering a kid at 82.
At least the flat screen TV's and communicaters materialized.

Ok, first of all....stay away from my tv! :D just kidding of course.

I consider myself very fortunate that this set is still in the family. I do have lots of great memories in front of that set and of course, Christmas, when my mom would put on the Holiday, Sing a long with Mitch record. There has not been a Christmas in my life, save one when I was restoring the tuner/amp when that record wasn't played. It just isn't the holidays without Christmas music playing through that ol thing.

My mother just LOVED it when I, at 4 years old, just got such a kick out of the sound it made when I rammed my toy truck into the leg of set. She always said that I just got the biggest thrill out of that and she just got furious. LOL Ahh, good times. LOL

That tv to me is kind of like that old Twilight Zone episode with the old man and the grandfather clock. He felt that if it wasn't maintained and constantly wound and if it stopped, so would he. Now I don't mean to say that if the set craps out, that I would croak, but a little part of me might, if you get what I mean.

I think we are all just senitimental fools when you get right down to it. :yes:

Totally agree, I have seen that Twilight Zone and I feel the same way about certain things. I am quite sentimental, TOO much sometimes :)

Very nice job! Nice set too! Its pleasing to have and old TV that was in your family, especially if old TV's are your hobby. I still have my parents "first" TV's, a '74 RCA 19" XL-100 (which was their wedding gift), and then they bought the big console in '81, an RCA color trac in the early american cabinet. They both still work like new after the thousands of hours on them. They are special sets that will always be kept.

Ok, the 21 is going to hop back on the bench for a little bit.

When cold, the raster has a green cast to it and I don't have much blue, until the set warms up after about 20 minutes. Could be a tube but probably a resistor or cap changing value but could easily be a solder joint I missed. There were a bunch of cold ones on the chroma board.

While this is a little bit of a setback, I needed to change one of the e-caps in the power supply anyway.

The set hasn't run much in the last several years so just gotta get the bugs out of it I suppose.
