And condensers... do they have to be new ones?
NO!...you can use old ones yes!...veterans tested... respectable guys you can trust..some of them may have reduced capacitance but your amplifier will be sounding good anyway.

What is the amplifier sensitivity Carlos?
was adjusted to 400 milivolts..because damn MP3/4 players.... people loves that awfull toys...what can i do?.... but this is adjustable...you can even place a trimpot in the place of the 470 ohms sensitivity adjustment resistor and then you can adjust it to enter 10 milivolts or 20 volts or more.... can use some terrible (distorting machines) preamplifiers.

Is it flat Carlos?
No!...and Yes!...it is flat electrically.... but dinamically, working, connected to speakers, it has it's own sonic signature...may sound with more mids than treble...more treble than bass or other combination..depends your speaker, home acoustics...how much wax you have inside your ears and mainly because sonic signature....MKIII-Hx loves treble.

There's much more to come...be tuned..i will continue to post stupid
questions to myself..this way you will be rid to post yours.

And about special capacitors... are they better?
Bull ship!.... there's a ship loaded with cows traveling in a nearby river ..i am watching it through my window.
They are almost the same...what matters is the capacitance and the way it is constructed internally...if coiled is not good..just that.

And special condensers...are they different?
Yes!...they are different... some of them are black,...others are blue..some are tall, others not..some are expensive..others not.
The big ones..the fat ones may have more room to fat electrons....if fat electrons mind with that..because when i force them to enter the condenser...fat or not fat will enter anyway.

But serious guys told me that non inductive resistances are better to place
into power transistors..in the emitter.
Ahahahhahahahahahahahahahahhahahahhahahahahhah!
funny these things....maybe they worry about electrons spinning... of course they may feel sea sick and vomit.

Dx buddy...i am powerholic.... crazy for power...i use to play loud
I want to bother neighbors... i want to play louder than anyone...i want to be really bad...can i increase your amplifier power?
YES!....increase transformer size..increase condenser value in the supply, increase heatsink till it will be at a refrigerator size (put a fan blower)...increase your rectifiers.... increase your mains supply energy..use thick cables to the mains...call the company to provide you more power..replace your home fuses for bigger ones..replace your home wiring (inside walls)...increase the power output transistor quantity and search for higher voltage and higher current devices to replace the original ones.....hehehehehe... 2 kilowatts is easy...very, very, very, easy... EACH CHANNEL MAN.... 10 percent distortion (sadly)
Well.... come to uncle charlie and i will help you to produce your earthquaker.

I am old Carlos... almost dead.... i want just a few watts not to vibrate my fake
teeth inside my mouth... you know Mister Carlos ... Sir... .... i am that one that cannot walk by the cemitery because souls try to have my old body at their side.... they use to say i am already dead and family forgot to put me in a grave.
ahahahahahah!
- Reduce your supply voltage man..also reduce the quantity of output pairs..use 8 ohms and be happy.

Mate.. are your amplifier better than Aksa?
So good as man.... Hugh teached me almost all i know... at least the most important things.
But we disagree in several things... supply condensers for instance..he has other ideas.... also we have fight because he love hot cappucino and i do like cold chocolate.

Can i increase treble?
Yes...it can be that one will broke glasses...reduce miller capacitor to 82pf and you will be shocked.
The amplifier is already crazy for trebles...better to increase that condenser a little bit.

And protection...have i to use protection?
Yes...better not to use pants without undershirt because of zipper..... fuses may be good for you...use protector if you want.

Have i to use all these transistors?.... they are too much!
No!....only if you intend to use low impedance driving your amplifier to 1 kilowatt distorted.... to use 8 ohms and lower supply voltages you can use one or two pair only....the way i use in my home edition.

But you have made an enormous amplifier..why that?.. when you use low power
Really...i use 2 to 10 watts each channel..so...Nelson Pass amplifier have the power we really need..the man is really good..it is not only fame...he is really good.
BUT.... people wants power... and i do things they may want to use...if i post low power (as i did in trust) then no one will want to build.

Is your amplifier the best one?... are you God?
No! ... i am not God..but i am his son....you too.
Mine is between the better ones...not exactly the best one.
But take a look how much you will spend to build mine ones and how much you gonna pay to have others ...hehehehehe

May i have to use these same transistors you are using?
No!... these transistors are the ones i have.. so, i have tested the amplifier with them..naturally they may be something more guarantee to you..but several others..hundreds of other models of transistor will fit.

Have it to buy boards to have your attention?
Negative!...you will have attention (even more) etching your own board or producing your amplifiers over a piece of wood with nails nodes to point to point....you do not have to buy boards...i am offering to the lazy ones (ahahahahah!) but i do like the most the ones produce by themselves.
I am not receiving free boards, nor Byron, nor Meanman, nor Alex mm....not money too... no gift or advantage to me....if you buy boards or not..really man this is not that important to me...what matters to me is that you build an amplifiers...mine or from others..but nine is better (hehehe)

Can i modify your schematic?
NO!... you can do yours...but please, avoid to publish suggestions of modifications in mine original threads..let my beloved amplifiers in peace..open another thread, say the amplifier is yours...based in Dx amplifiers and go ahead and do not mess with my thread please.

Can i say the amplifier is mine?
Yes..you can...after modifications it will be really yours....your problem too...your responsability too... you will give follow up and will listen complains if something goes wrong..hehehehe...go ahead man!
This is the main reason a lot of folks tries to change other guy's designs not to show their own ones..they have not courage..it is better to go with you and not to put their own skin in danger.
