Radio? Naw, we were way beyond that. We had one of them Fairbanks-Morse TV sets, and a 19 incher at that! It got one channel (ch. 5) CKX-TV in Brandon, Manitoba. A year or so after first firing up that technological marvel, we we able to get a second channel, Ch. 12, KCND-TV in Pembina, North Dakota. "International television" without a satellite dish. (Sputnik wasn't available for TV then). The lavish entertainment fests on these two channels could only be accessed through something called a rotor antenna, which involved turning the antenna out on the roof via a switch located on top of the TV. Which usually froze up and stuck in the winter.
And look, we stayed on topic, didn't we? The science of video waves (?) and the technology of television coming together to bring Ed Sullivan into our living room every Sunday evening. In vivid black and white. Well, actually, mostly snowy-gray. Ahh, those were the days... :lol: END OF HISTORY LESSON
We had one of those too. After TV came along, I converted to a guitar amplifier and it's entertainment days were over. The thing had a giant speaker in it (about a 12 incher) and sounded really good. Until I hopped up the amp. and blew the cone. Science and I have never gotten along too well.
the science of 'remote' control, I never could have imagined not havingto get up everytime the channel had to be changed, amazing.For awhile I began watching the TV on the floor closer to the set, sothat I didn't have so far to go to do it. Layed on the floor with apillow so I didn't block anyone elses view.
Yep, I can relate. I had to lie on the floor close to the TV to try and make out what was on the screen during bad weather. SCIENCE and technology has come a long way. (But the Long Ranger, starring my hero, Clayton Moore, isn't on anymore) :-|
Er, better make that "Lone" Ranger up there, not Long Ranger. It was a children's show, after all!
My Mom always threatened me with Television eyes if I kept getting so close. It was the easiest way to see through the ghosts
I was just a kid back then, but my brother was 12 years older than i,and I remember watching him changing a tube, or something, and thenext thing, he was on the other side of the room up against the wall,as he got a mighty shock, that taught him to check the cord next timeand make sure it is unplugged. He survived, but his eyes looked bigger.
I did that with a capacitor in an old guitar amp - and I should have known better too. I needed power on to see the problem. My wife came running downstairs fearing I'd shot myself only to find me sitting (stunned) on the couch spattered in tar and tinfoil ... and all I could manage to say was WOW!
Yeah, they weren't exactly user-friendly things. We rebuilt the chassis on ours and installed twin 6L6GC tubes as used in Fender amplifiers of the day. I can still remember that tube number as they cost a bundle! The fiddling ultimately caused the speaker failure, but we were participating in an informal SCIENCE study at the time, as I explained to my mother.
Here's my take JLM,
Science can't exist without logic and human tendencies. Without using logic, the methodology of practicing science is a waste of time, but the power of science comes from the use of logic. Human tendencies create the framework for questions to be formulated, and to address the needs we humans create for ourselves.
Science is a means to an end, and it's scope is that end: to gain understanding about the physical realm we inhabit. This is accomplished really in two primary fashions: observation and experimentation. Observations of real world phenomenon are beneficial because they help guide the hypotheses through which experiments are designed. Experiments are designed to help elucidate the fundamentals of the observations from the real world, but are limited. They aren't easily transferred to the real world due to the specific conditions in the lab. But they are needed, because there is no way to detect or estimate the proper interactions between variables using only observational evidence. You need to experiment to determine that.
Without going too much farther into the guts of it, experiments are models, guided by observation, and validated by using those models to predict observations. It's an intricate dance. The best method we have for understanding the physical world.

What do you mean? They both start with "a" and they are both alive, any more alike and they'd be twins....................:lol::lol::lol::lol:
Wouldn't have mattered if the power was on or not - capacitors keep their charge until discharged. Kapow!
:lol:Lookit the money and aggravation I've saved by staying acoustic......
Nobody would let me in their band anyway....
Glad you only got "half baked", Wolf.
