except for Radio Ray

His setup including the price of the truck and everything in it only cost him about 30,000 to do. And even he is a mudduck compared to a lot of guys out there. Just food for thought.

Stop and think for a moment. 35000 watts required a AC alternator bigger than most home stand by generators. As an example take the GUARDIAN 13kW http://www.guardiangenerators.com/Pr...RDIAN13kW.aspx I requires a Generac 992cc OHVI® industrial engine just to supply 13kW. You are talking about having three of these mounted in an auto. If you have a 454 mounted in the suburban almost 40% of it's power would be required just to supply the AC alternators.

Look at: http://www.ssbtractor.com/PTO_generators.html Notice the size of just the AC alternator. Or go down you your local Home Depot and look at the size of of the AC alternator on one of their 8000 watt generators. Then remember you are talking about mounting at least four of these to get around 35000 watts.

Actually it only takes 3 320 amp AC alts to produce 35k watts at 2800RPM. You see in these trucks the AC alts pump power to multiple transformers inside the truck that produces the voltage to the tube amps.
You forgot to get 35Kw output required a DC input of at least twice that amount. Plus half that amount more for the modulator. So I don't think your 3 200 amp AC alternator are going to cut it.

I also have to wonder why GUARDIAN 13kW generator are so poor performers. And why it takes a 1000 cc engine to run it. Remember that is just one and you will need more than double that to get to 35Kw.

It's actually 3 320 amp AC alternators.... :roll: And do you even know how a tube amplifier works?? The transformers turn the amperage into volts in excess of 15000 votls to power those tubes.

It is a little different than a generator producing wattage alone, and requires no DC power to the tube box itself. I'm also guessing you would call me a liar if I told you there are 70-80 thousand watt mobile rigs out there huh?

Oh and www.cbradiotalk.com is worthless, all they want over there is your money. And most of posters and moderators are completely clueless about CB radio. Oh and Mike from radioactive radio's is part owner of that site, he is one of the biggest hack jobs out there.

That kinda wattage seems like an electrical disaster waiting to happen.

You said: "And do you even know how a tube amplifier works??" Well my friend I do know how amplifiers work. But it appears you don't.

Using your example. From the AC alternators they feeds a circuit called a phase combination network. From this network a step up transformer would increases it to 15000 (using your number). Once this is done the AC voltage is converted to DC. All vacuum tubes REQUIRE DC on the plate element of the vacuum tube. See: http://www.radio-electronics.com/inf...sic_theory.php Notice the picture labeled "Concept of vacuum tube diode with cathode and anode." See the element labeled Anode. It has a postive voltage applied.

Would I call you a liar? No. However I would highly doubt it. But knowing the mindset of most CBers I could believe they think such an amplifier exist. Just like you believing the one you having been describing is a 35Kw amplifier.

I don't know anything about www.cbradiotalk.com I don't have any need for there service or be a member of their forum. Being I have been a licensed "ham" since 1958 see: http://www.qrz.com/ and enter kc0iv in the callsign look-up box for my current license. The holder of a General class commercial license since 1976. BTW I am a retired design Electrical Engineer. I also hold a patent on a RF controlled device used in the dairy industry.

Now would you care to list your electrical knowledge?

OK, then, you can answer these questions 3 (no, that's 5 sir), and ye shall see the other side...
How many electrons can you fit on the head of a pin.
Why is there a 'halo' around lightning rods on top of my barn during a thunderstorm?
Why does your hair stand up if you get too close to high voltage?
Who invented the Tesla coil and what did he propose to do with it?
Why does a florescent light bulb light up if you hold it under a high voltage power line?
Get all answers correct and you'll win free truckloads of dispatcher brains, cordless extension cords and battery powered DVD rewinders. Be sure to ask for special deal #OU812.

:withstupid:

Blue, no yell.....AAAAAHHHHHHHHH!!!!!

I was wondering if anyone would catch the M. Python quote....(even though it was a little bit misconstrued....)
What is the airspeed of an unladen swallow?

You ask: "How many electrons can you fit on the head of a pin." - You ask an incomplete question. To answer such a question would require additional information. Such as the size of the pin, type of metal(s) used in the pin, the pins taper angle, surrounding area coupling, etc.

You ask: "Why is there a 'halo' around lightning rods on top of my barn during a thunderstorm? " Improper grounding. A properly grounded system will discharge the high electrical stress before it causes the gas to partially ionize and begin conducting.

You ask: "Why does your hair stand up if you get too close to high voltage? " Static electricity.

You ask: "Who invented the Tesla coil and what did he propose to do with it?" Nikola Tesla. As a way of transmitting electrical power without wires.

You ask: "Why does a florescent light bulb light up if you hold it under a high voltage power line? " First the word is fluorescent. It is cause by the magnetic fields coupling between the power line and the mercury vapor of the fluorescent bulb resulting in a plasma that produces short-wave ultraviolet light. Which in turn causes a phosphor to fluoresce producing visible light.

Judging from your questions it would appear your education level is around a fifth or sixth grade level. Quite common for those that attended the public school system. Since you are in a trucking forum it would appear you must be mentally challenged. And as such you would be the perfect candidate for one of those 70-80 thousand watt mobile rigs jegzus claims.


Have a great day.

When lightening strikes your car, your not hurt, why? It's because of the rubber wheels.

In a car, you are in essence inside a what?
