Hey guys, if you can snapshot a pic of your roundie in operation, Im curious as to how well these sets seem to look quality wise after all these years..

Here's my ctc-16 in it's glory, but still workin out the bugs..

Hi;

Here's my contribution. The set is a 1959 RCA "Anniversary" model CTC-9 chassis.

Nice Pictures!, no roundies in my collection ....yet!

now that is a picture!!!! hope my roundie is half that nice.i will post picture when finished. don t think it will be nowhere near as good as that one-awesome!!!- to say the least.

Bob,

Your CTC-9 images are stunning. The 40's era Technicolor musical "State Fair" is a great choice to show off your set. Images from my CT-100 and CTC-5 are on my web site below.

Hi, and here are two recent screenshots from my 1956 RCA CTC-5. Note that the 21AXP22 is not as contrast-rich as the later picture tubes.

Here are the photos (updload didn't work since I have to reduce the image size).

Hi Steve;

I was wondering if anyone (except for me) would recognize the film that my screen shots were taken from.....you've got a good eye and apparently a good knowledge of the Hollywood Classics. I LOVE those old Technicolor films, the colors just seem to jump off the screen at you.

Thanks for the compliment and as always your web site remains an excellent example and reference source of information about the RCA CT-100 and CTC-5.

Eckhard...I think your CTC-5 screen shots look terrific!

Bob

WoW! Those sets look stunning!! Much brighter raster and than I have, But im sure it's all due to the intellegence level of testing and repairing the malfunctioning circuits, as I dont have really any test equipment besides a tube tester... But my hats off to you!! If only my darn CRT tester would show up! lol

Check out my 1965 Zenith.

Pictures were too large. Here she is.

Here are some pics I had saved on the computer. CTC-5, 11, 15 & a couple pics of a T1000 Admiral.

That CTC-15 in the cherry French Provincial cabinet looks great. It is a pleasure to see so many working roundies. One common thing I have noticed is that when properly restored, they are nearly all capable of a great picture. Whoever thinks roundies don't have good picture quality has never seen one properly set up. Once i got my Zenith working, it completely put me off of modern sets, even flat panels.

What could be better than owning a roundie??? Having 2 roundies!!!! Those sets are amazing! Did you guys replace all the caps in the sets or just the critical ones? I might need to replace the paper caps on the IF to clean up the smearing in the color ion my set...
Congrats on those sets!

Roundies have amazing color rendition. I can honestly say that you guys have some of the cleanest, nicest roundie sets I've ever seen.
Brian, I love that Admiral, truly a beauty.

I am very impressed. Once I get my Predicta restored,, I am going after a roundie... love um.
Dan

I have not yet done a full restore like this, but when I do, I will replace every non-ceramic, non-mica cap in the set (and I will check all the mica ones as well). You "may" get a set to work without doing all the replacements, but it will just be much more reliable and you will have fewer "unknowns" if you do.

My 1963 Philco. It still has a bit of a problem with horiz linearity, the picture is a bit more squished together horizontally on the left edge of the screen, otherwise completely operational, I usually use it at least once a week. I replaced all the paper and electrolytic caps, a few weak tubes, and had to realign the chroma oscillator, I plan to look into the horiz linearity after I get a few more of my b/w sets working.

I've only had one roundie color TV in my life, a Sears Silvertone (RCA CTC12 clone) from about 1964. Got it in 1970 from someone on the next street up from where I used to live. I don't have it any longer, unfortunately, because the video output tube socket broke out of the video PCB with a sickening crunch some time in 1973. The set didn't have a bad picture, even on rabbit ears, but it could have been a lot better had I had a good color bar-dot generator to touch up the convergence. The set also developed a color-sync problem and hum bars in the picture near the end; the hum bars were the reason I was trying to replace the 6AW8 video-amp tube. The replacement had a bent pin (unbeknownst to me until it was too late), so when I tried to push the tube into the socket, I pressed down a tad too hard on the tube and--crunch! :no: The socket, with a piece of the PCB, clunked to the bottom of the set immediately. I tried to repair it, to no avail, so, when I finally moved out of the house I was living in at the time, I left the set there.

I wish I would have taken a picture or two of my roundie so I could show it off. It wasn't the best looking set in the world (black metal cabinet with threaded holes in the bottom, presumably for optional consolette legs), but while it lasted it served me well, both in my hometown and where I moved in 1972. I often think of my '64 Silvertone roundie when I watch my modern (ca. 1999) 19" RCA table model, and am amazed at how far TV set design has come in the last 43 years. But the memory of that tube socket crunching through the set's video PCB will be with me the rest of my life. The TVs I had after that Silvertone were good (I had a Zenith SC300 19" portable in 1977, among others), but I kicked myself (figuratively speaking) for years after losing the Silvertone set. I mean it; I missed that TV from the second the tube socket broke out of its circuit panel (and for some time afterward), but a later find, a 16" (more or less) Silvertone table model found on a curb in my hometown in the late seventies (not to mention its successors, of which there were several--all b&w sets; no more color sets until I moved here in 1999), made up for it.

Living in a small apartment these days, I can't collect old TVs anymore, but the memories of my Silvertone/CTC12 will live on in my mind for years to come. That set would have had a great picture, as I said (at least for a while), had I had the proper equipment to reset the convergence; but it was one of those early sets with the PCBs that broke at the drop of a hat (made from phenolic, I think), so I likely would have had other failures eventually even if I could have repaired the video output socket.

Am I okay to show a British round-tube set? We never actually had round-tube colour sets over here except for the ones which were used for experimental or training purposes - Some British-built, and some shipped over from the US. This one is a 625-line PAL set made by Bush in 1963-ish. I haven't had to do an awful lot to get it going, but I have bodged the burst-gate to get the PAL switch and subcarrier regenerator to operate correctly and that will need fixing properly sometime soon. The attached picture of the set (model CVB100) is quite small, there is a bigger picture at: http://www.oldtechnology.net/misc/CVB100.jpg

Kind regards.

From Mike.

Here are some screen shots of a RCA ctc 15 color set. This set was hooked up to the dtv box and the picture is really clear. I don't like the way the government went about the change over but it does work vary well.

BEAUTIFUL SET MIKE! I love the cabinet styling and the picture is phenomenal. Great job on the restoration.

I think the DTV boxes are a great thing. They seem to have a better appearance over all because of the ability to cram more color information in the signal. Colors are brighter, clearer, better contrast and finer detail.

You might check the linearity on your 15. Looks as though the picture is squashed a bit on the bottom. Other than that the color looks great!

OK to show? It's marvelous!


Couldn't find "bodge" in my English-to-American dictionary, but as long as it worked, I guess it's OK :thmbsp: :D

Mike,

Your 625 line Pal roundie is fantastic. Thanks for sharing. Seems there was quite a bit of experimentation with color tv across the pond in this period.

-Steve D.

Thanks everyone. :)

Bodge = Temporary low quality fix. :)

Ah! sort of like a soft fudge.



And roundscreen, beautiful screenshots; I get/see the same kind of improvement with the CT-100 on a box.

These aren't new shots, I posted them on another thread some time ago. Just thought I'd link them here too, in case whomever wanted them collected here wants mine here too. These were OTA UHF with set-top reflector antenna from about 15 miles from the transmitters. CBS and PBS (15 and 39).

I would like to try a DTV box on this set sometime, but since these photos were taken it's developed hum bars in the picture, a sure sign of a failing PS filter cap. The set is unrestored, lucky to still be working at all -- just not smart to turn it on anymore until repairs are made. Will need to address that issue first, then I'll DTV-box it and evaluate.

Reminds me of a statement by someone in the book "The Making of Star trek" that came out around 1968 or so. One of the people involved in the making of this show said that it was going to cost him $400, as he was just gonna have to buy a color TV to watch Star Trek on.

Duplicate post. Ignore.

The tire does look flat in that picture. I noticed it when I was watching the airplane dvd the other night. Cleaned and adjusted the vertical size and lin controls and the linearity looks normal for now. I have put a lot of hours on this poor set but she is still going strong.
Watching the dtv on a ct100 has to be so awesome. I was relieved to see how well the dtv worked on rabbit ears. The next thing I have to do is hook the box to the roof antenna in the attic. I should get more channels with it and the uhf will get a stronger signal.
Kbmuri. Make sure you replace all the caps in your Zenith. You will be putting a lot of use on your set when you see the dtv on it.
Ed

I'll try to post a picture of my CTC-4. Hope it attaches ok.

Oh Well....

Here's my Zenith. Can't remember the model number...

In Pic #2, is that a Brookfield insulator on the floor? Do you collect? (Sorry to float off topic, just seen it there)

I would post a pic of my Roundie in operation, but I don't have it yet.....and Doug if you are reading this put down your Space Command 600remote AND..........GET Cracking.....don't make me get the bat :D

I have wondered what sort of color set would have been in England. I bet such a TV was in Buckingham Palace and the homes of The Beatles, etc.

Darn, good eye! I really didn't know off hand the make, but you were right. I wouldn't say I collect them, but I do have 15-20. Most were given to me when I was around 12 y.o., by a fellow who had what must have been thousands of them in his garage. Too many other things I'm into to get serious about them as well. Someday I'll take the time to look up what I've got, I'm sure there is some interesting reading out there.

Here are two snapshots of my unrestored CTC-11. I started replacing the electrolytics, but a bunch of distractions got in the way. One of these days . . . :-)

My RCA 21CT55 is configured as a composite video monitor. I see no logic in attempting to get the tuner and IF sections operating and aligned with OTA broadcasting shutting down in Feb. I'm presently doing an optimum chroma setup and PQ evaluation by comparing the RCA screen against a Sony professional monitor. I am convinced this method is the only way to get the full performance potential from this 53 year old roundie and demonstrate the RCA's PQ relative to a near perfect NTSC standard. I've posted some of these screen shots on the PhotoTrail free site. Included are stitched photos of simultaneous screenshots from both RCA and Sony monitor:
