hi all im new to the forum so hi to all

i have a question that i cant find an answer to.

i have a 555 frequency generator, putting out a frequency of about 43khz.
im looking for an amplifier capable of amplifying this signal.

looking for a total output power of 50watts or therabouts. the only idea i had was to get a schematic for a 50watt audio amplifier (20khz max) and modify it to accept 43khz

the input/output impedance needs to be 50ohm as it will have a bandpass filter after it, this will then goto an antenna

i would like to use the 43khz frequency on the amplifier rather than a 10.75khz harmonic

any help on how to modify an audio amp would be great, a schematic would be even better.

cheers guys
 
Many audio amplifiers go up to hundreds of kHz.
50W into 50 ohms is an output voltage of 50VRMS or 100V p-p for your square-wave.

Are you using electrolysis of water to make hydrogen and oxygen to add to the intake of your car so it will burn its valves and pistons and make too much nitrogen oxide pollution? HHO does not work!
 
the project is for hho production yes. But however its ot added to the air intake and nor does the engine run lean.

the engine runs on just hho. i did read some of the arguements in another thread on here and while some could be considered valid, i dont belive that they are projected with all the facts in mind....i for one have a 9.0hp honda engine completely modified to run on hho, this involves a custom made carb, electronic ignition and exhaust as well as retiming and valve timing.

although you dont belive that this technology works please dont leave my question unanswered,
is there an amplifier you could suggest that can amplify this frequency range with great efficiency, i was trying to steer away from audio amps due to that they have 8ohm output and would require impedance matching which i havnt got a clue how to do...unless you can point me in the right direction on that one aswell

cheers
 
I have never seen a car with a tiny 9hp engine so maybe you are powering a lawn mower with the hydrogen fuel cell?

I don't think only 50W makes enough hydrogen. An engine that produces 1hp uses 746W worth of fuel if there are no losses. So a 1000W fuel cell might make enough hydrogen to power a 1hp engine.

Most audio amps are class-AB with an efficiency of only 60% but their frequency response goes higher than 43kHz. The 60% efficiency is with a sine-wave so they will have a higher efficiency with your square-wave input and output.
Class-D audio amps have a higher efficiency but have a filter at the output which limits their max frequency to about 20kHz.

An amplifier with an output of 50W RMS into 8 ohms has a square-wave output of 57V p-p.
Since you want 50W into 50 ohms then a custom-made transformer can stepup the voltage to 100V p-p but the amplifier would overheat since music is not at full power all the time.
Or an amplifier rated for 155W into 8 ohms will have an output of 100V p-p and would not get too hot.
 
Check out the Supertex MD7120. I've only seen the data sheet, but it promises to deliver +/- 100V swing at pretty high frequencies. Perhaps they have a good application note with a complete schematic and parts list. Drawbacks include where to buy it, and it is a QFN package which will be challenging to solder.
 
cheers for the info guys, this may help you see what i want to achieve.

audioguru quite rightly said it takes about 750 ish watts for 1 hp
this is in terms of brute force power. what i am trying to do is achieve resonance. im sure you will all agree that you can destroy an object when you match its resonant frequency.. the idea i have will not use any steel plates or electricity blasted into water. it will instead use electromagnetic radio waves broadcasted at 42.845 khz (apparently waters resonant frequency)

i assume by your previous post audio guru that class d amplifiers would be the type used in cars???
is it possible to modify such am amplifier??? i would guess not but worth a try

the md7120 chip looks very good but a little bit over the top for my application but then it is still an option

idealy i would opt for an RF power amplifier with an LC Tank circuit so i can tune it myself to the frequency i need. in reality i belive that 10watts will be acceptable but 50 watts would allow me more power to conduct research
 
Don't waste your time, HHO is a scam and the effort, time & money you put into it will never be returned. www.Overunity.com has lots of HHO projects that don't work.

Scientific proof debunking the "run your car on water" scams

yes i agree m8 the "run your car on water" "water4gas" etc are scams.
these use mason jars or similar with upto 80amps running through them and only produce 1 litre per minute of gas.

however i asked a question about modifying or making an amplifier for a specific job i assume that it was the frequency i asked for that gave it away that it was for a hho project.
i have tried to explain what i want to do but everone i ask (not just you guys) always seem to say dont boter its a scam etc etc

this is not a scam as i have designed it so therefore it cannot be a scam. this is a project that i have decided to build after reading all the facts. and the fact that i have a cell that can run a 9hp 350cc engine on its own and runs self sufficient proves to me this is valid and viable technology. the project i am currently working on is about the size of a small car and will be used for energy (electricity production)

any more help on the above question would be most appreciated.
oh i forgot to mention before the signal generator produces sine wave
 
Stanley Meyers wrongly said that water resonates at 43kHz. His patent was never proved and he was sued in court for fraud and lost.

Water resonates at a 2.45GHz microwave frequency. That is how a microwave oven works. Then the resonating water molecules heat up and turn into steam, not hydrogen and oxygen.

An ordinary car radio has an ouput at clipping of about 14 watts per channel into 4 ohms. They are bridged class-AB not class-D.
 
idont want to get into an argument on this but 2.45 ghz is NOT the resonant frequency of water, many people have said that it is when it isnt.

a microwave works by vibrating molecules which makes them rub against each other causing friction and in turn causing heat to be made. a microve no more resonates water than a kettle both boil water and both make steam and the probably even use the same power to do it.

ther ehave been many people using the 43khz frequency to produce hho from water. keely, tesla, meyers to name a few. bob boyce recently made a cell using this frequency and its harmonics produce 100 litres per minute from 60amps

this technology does work and it will only be a matter of time before someone cracks it. there was a quote on the tv for the new synergy drive from albert einstein......."if at first, the idea is not absurd, then there is no hope for it"

i quite like this quote, it drives me forward. you are not the first to try and convince me that this is all fake. only the fact of the matter is i have a working prototype that does the job. if you are ever in newcastle i can arrange for you to take a look.
 
Of course HHO in a car is fake because nobody has proved that it increases the fuel economy.
 
but im not using it in a car so your theory is flawed, anyway im not getting anywhere here so lets leave it at that. its pointless argueing over something we will never agree on so lets agree to disagree.

cheers for the info you previously provided

In what way does it work? - obviously you can create hydrogen and oxygen by electrolysis, and you can then burn them in an internal combustion engine to get mechanical energy from it.

The trick is how much energy it takes to split the water, and how much mechanical energy you get out at the end - you ALWAYS make a loss, and a considerable one.

The 'holy grail' is to use the engine to feed an alternator that spilts the water - but this requires over 100% efficiency, which is obviously impossible - and is why no one has ever managed to do it (and probably never will).
 
HHO has already been demonstrated at a scam over & over. Show us a link that says water resonates at less than 2.5Ghz and even then all you get is steam.
Your best bet is travel over to www.overunity.com with the scads of others who belive the fairy tale and all but worship Stanley Meyers.
 

this is mostly true, yes an engine is used to run an alternator to produce power to run a cell to produce hho and this hho runs the engine... you say this would require over 100% efficiency. this is only true for brute force electrolysis where a battery is just connected to steel plates in water.
HOWEVER the system that i and many others are experimenting with uses pulse waves to allow the bonds in the molecules to bounce like springs. to do this will take up very little power as all i am doing is making the water resonate. now the trick is that when these springs bounce to there strech limit they become very weak.....while they are very weak voltage that is constantly being fed into the water at very low amps somewhere in the region of 5 amps. the water begins to break into hho rather rapidly.

now to summerise 12 volts @ 5 amps with excess of 80litres of gas per minute

do the math thats IMPOSSIBLE. OR IS IT.

i have this system working and am in the process of perfecting it to produce more hho. hence my origional question above
 
LOL yea right. More pseudoscience gobblygook. I'm sure there is a yootoobe video of it out there.
Show us how it's done and we'll be happy to tell you why it doesn't work as you claim.
Here's some reading that should help but probably wont.
