A tube to make a black & white tv color

[damen]

Funny this person thinks a new color tube will bring color on a black & white tv.

Pretty funny!

My God the people now days. That is so sad it's funny. Just a crappy '55 RCA B/W, I wonder who told them it could be made color with a new tube. What a maroon.

Don't forget the generation gap here.

The person who owns this set quite possibly has never seen a monochrome TV in his/her life, and does not know that some TV sets produced only a black-and-white picture.

I told my nephew there was a TV he could watch in the breezeway, he came back and told me the TV was a toy because it had no POWER button.

After I take a picture of my nieces with my Realist, they patiently stare at the back of the camera waiting for the picture appear on the (nonexistant) LCD screen.

Yep...I remember when Bethany & Shay 1st started comin' over here, they staated playin' w/my turntable, but couldn't figger out how to work it, as it didn't have a button to push to make it go to the next "track"...They'd NEVER seen a TT or "records" before....

I must confess (with a little humor) to being on the other side of this generation gap.

When I was about 17, I read an electronics magazine with a reference to portable radios from the 1930's.
I took it to be total pseudoscience, since I knew the transistor was invented in 1947!

Today, of course, I like to listen to CFZM 740 using my homemade 90V "B" batteries on portables that use tubes.

Hey wasn't the transistor discovered at the Roswell crash site? Not sure if I believe that one, but I digress.

Do they make a tube that can make an HDTV display SD without smearing and pixellating? If so I want it!

[Robert Grant]

You can make such a tube:

Take a hollow tube (a paper towel roll core will do), attach a concave lens (aka negative lens) at one end, and a convex lens (positive lens, magnifying glass) of equal value at the other.

Now face the concave lens end toward that 56" plasma, and watch TV by looking into the convex lens. Your SD picture will be pinsharp, and you won't notice any pixellation.

LOL

Perhaps they meant to say "picture tube"?

When my daughter was about five years old, she got the mumps and had to spend a few days in bed. She wasn't allowed to have a TV in her room, but I figured since she was sick I'd be nice. I took an old portable in and she was thrilled that she was going to be allowed to watch cartoons in her room.

A few minutes later she came out of her room carrying the TV. I remember her words exactly as she handed it to me with a sad face: "This TV is broken, dad. There's no color." And she meant it... she wasn't going to watch in black and white!

Another story, more recent. We hosted a tour of cub scouts at our club's museum a few months ago and the TV exhibit was a highlight for them. (They even tried to understand the black and white issue!) A number of the kids asked really perceptive questions, but one kid cracked me up completlely when he asked me if "that thing" (the rectangular plastic RCA logo on the front of the fifties vintage set they were watching) was where you put the disc!

I remember in the early 90s selling b/w tvs at the flea market and i always got the same questions

Is it color???
Is it cable ready???
Can it be converted to color ???
Is that one of those old tvs that uses the tubes ??

Never forget those questions i always got asked .

Had one kid buy a pota color off me in the early 90s and he brought it back to me claiming it didnt work . So we plugged it in at the building and off coarse it did work . The kid didnt understand why he had to wait for it to warm up . So i had to give him his money back becuase he was absolutly sure that a tv does not need 5 or 10 seconds to warm up . He swore i was trying to pull a fast one and was selling him a lemon . Never forget that one either ,

You should have told him that they only used a 20MHZ 68040 cpu for the DSP and that it took longer to boot. Maybe he'd of believed that.

One thing that ASTOUNDS kids when they come here is my working Victrola... Another one is the 3" Pilot...

The positive side is that old radios some times are sold dirt cheap because "it will probably break in the near future, even now it takes about half a minute to start up". I never care about that, i just buy the anyway.
