Default More simulations images

Made with the Multisim 2001.

The amplifier is sounding very interesting...try it!

To keep some animals, the ones sensitive to high frequencies..... out of your home.

Insect killer

Mouse

Some sensitive Cats

Noisy Dogs

Default 50 Watts in 10 minutes, version Turbo under test.

This version put together the last (century) technologies, having some new circuit , having NCCS, Not Constant Current Supply, and astonishingly new leaked electrolitic condenser output....this new model have less coils inside and prevents eletrons to feel alike drunk to make the turn movements.

I cannot tell you that it uses 100 volts and bigger and hard transistors, also the half voltage adjust resistor changed a lot...but this is all secrets, i cannot even tell you that ot is the same amplifier with the "turbo" name on it.

regards,

Carlos

You should replace the 470 ohms resistor with a current source, either made up from two resistors and a capacitor or made from a transistor, some diodes an a resistor.

Default If i do that, it will sound as others.

Make it, adjust carefully, check the VBE voltages and go changing to the best satisfaction.

Then, take your "Golden Model", the one you like.....adjust it to 7 watts maximum at peaks.

Using same speaker, and same sound source.... guarantee that putting cables in parallel, the input cables.

Adjust your amplifier to measure the same power at peaks.

Call your Wife, Son or Daugther, one switch already made by you.... to switch from one amplifier to the other.

Put some Dot over the switch.... and ask Kids to go switching.... do it for some minutes and ask the switch operator to take note of the switch position.

Repeat that test again.

Now go to evaluate, you will know the result....

Now put your Wife, Daugther or Son, sitting on the Sofa and you will operate the switch..... do not tell them what position corresponds to what amplifier!..... repeat the test many times.

The result you will see.... you will conclude that simple can be almost so good as complicated....maybe some interesting surprise to you...maybe not.

Also you will see that Dogs, Cats, Wife's mother and all kind of terrible things to have inside a house....hehe..... they will disappear.

PLEASE, THE ONES READING ONLY THE LAST UNREADED THREAD!

There are some simulation results published at this thread...i do not trust entirelly in simulators, but they are a very good calculator machines.

To say if something sounds good or bad...have to make many blind testing.

Of course, some "State of the Art" Australian amplifiers from Aspen or Mr. Magnific John Lindsey Hood and all their clones will kick this amplifier a-- easy and laughing loud.... if you have one, or already heard those....do not loose your time with that trash!...but only if you already heard those!!!!

regards,

Carlos

Carlos, I agree with you here. I've wasted a lot of time building sub standard "trash". Well trash may be a little bit harsh, but I know what you mean.

Good night

Default A perfect communication include the sub text, real life common experience and facts.

I think we really could communicate.

And this is much more than words.

The more complicated, the more sophisticated, normally, the worst the sound is.... dennie the basic rule, a wire with gain, nothing to distort, to change, to create time constants, to correct nothing.....if have harmonics...let it be....life is harmonie.

The more simple, normally sounds agreable.

It is frustration to me, having only John Lindsey Hood, his Clones and updatings ,and those fifty fives from Hugh. Related to tubes, i could hear many amplifiers that i like.

But something not so artificial, so against the natural sound can be founded, going simple.

The not natural sound, i can explain what i mean asking you to compare one piano playing and one those keyboards playing "piano"....that's the difference!....easy to see...also natural Orange Juice and not natural Orange Juice are different.

This have nothing related to measurements... measuring good can sound awfull, and the opposite is also true....have not related to "Intra Conceptional Micro Derivated Perceptive Difraction of residual Magnetic Field gaussian losses"..... it is simple going out and hearing music alive..... play your own acoustic guitar..... play your own harmonica..... kick some oil barrel.....It is so simple that the more intelligent people cannot reach that simplicity..... those people, never think the damage can be the fuse!

All amplifiers are Sinthetic....no natural sound, all i could hear, excluding those two i told you..... related to Hugh....the secret is so funny....people will never discover...never!

I will never open my mouth related that. Will died with me, showing me everyday, that things are simple, people create all the complications.

Now the problem is Arabian.....yesterday was Japanese and Germans..... tomorrow will be another "duck"..... people never learn that 50 years after those awfull things they have been doing, will be having dinner together and having fun..... why start some strike?

regards,

Carlos
