Wow....

Its like my dreams come true.. I was so damnly worried about short protection or load protection circuit for DX.. It is very nice to hear my uncle charly is thinking of it 🙂

I tried Quasi's amp with an SMPS to make a mobile amp (one of my dreams is to build a mobile amp for vehicles) but still without a short protection.. and the SMPS I copied it from another thread (power supply for quasi's amp as i remember) and changed it according to my requirements.. I have the schematic which is by Alex mm 🙂 may be the same power supply can be arranged for DX with a little modification (just an idea..)

My next plan is to build stereo mobile amplifier using DX 🙂 .. i'm worried about the size.. hahahahaha

I'm sorry if this is out of the topic..

Dear carlos you know i'm a lost person.. so I don't know how to help people instead of helping myself first.. I havent sell a piece of **** yet.. I'm not good at marketing.. but I wish I'll win that too..

and I wish your dreams come true one day with the DX corporation and I have myself for you if you are recruiting me... Please find a good brazilian wife for me.. hahahahahaha...

I thank you all who helped me directly and indirectly 🙂 and specially uncle Charly who is my master of amplifires... I follow you...even though we have many differences...

regards,
Lycanlk

Thank you Lycanlk..... i really think different my dear

I will, one day, produce short protection, speaker insertion delay, Dc voltage detection in the output...well, all these things....and because "DIY market pressure on me".... in the reality, i would prefere an amplifier so huge, with so big heatsink that can manage a continuous short circuit, overheating alike an oven, cooking eggs over the heatsink and able to fried steaks too...and without burn...and this happpens using several transistors and big heatsinks...that's what i would like...but this is expensive, not good for DIY market (builders) and not good to sale in the future to the wide world market.

I am not too much interested in profit, i do not think this brings happyness, nor too much pleasure too..i was wealthy, travelling whole world...money was not a problem to me.... but was not happy... since i decide to give a hand to others i felt good..really good.

To have millions of amplifiers, one unit each home, wide world (big target...i can have Dx amplifier in PC speakers, home theaters and so on.... to to that i will need to enter to the "system".... i am trying DIY, for free, in foruns....but quantity is not the one i was dreaming...to increase the quantity i have to produce boards to make builders life easier...and believe me, this is a problem, because customs..... my country bureaucracy is creating some troubles.

I had Nico Daneel producing boards...but i think he had not time to start the whole thing..i suppose a disease made him disappear.....or he is the Chinese one that is seeling a lot of Dx Amplifiers..ahahahahha!...i would be happy if Nico was behind that.

You know, i think Audio Divine Protector, the God of electrons, does not want me to do.... really because i will make so good, so huge, that no one will be able to beat, sacrificing profit to make the best...then this will kill enormous ammount of competitors...not very good...as i do not want to enter the "system" to be rich, but to provide the best.

I am not the best, but i want the best, so i am collecting ideas and designs from the best designers and put them together...so.... i have their inspiration and their knowledge to help me to do the best, even not beeing the best....observe.... my inspiration in my last amplifier.... Hugh Dean and Douglas Self..heheheheheh...unbeatable match!

The one had the desire to make automobiles using aluminium could not make it...as this was an amenace, a trouble to the big International Corporations... a car that would never be destroyed by weather...lasting for life long...also some brazilians found a method to use water as a fuel..... big Corporation bougth and destroyed all plans about..bougth to silent him...you know..enormous Oil companies.

If you forgot profit..then you will beat everybody.... so, i think my ideas are not so good to feed the "free market" style..... disposable and cheap things...based in the philosophy of profit first, fashion second, beauty third , quality fourth, reliability fifth and audio quality sixth.... and i would like to invert this sequence.

Take the Dx amplifier, for instance,overdrive the input... use a square wave generator, increase it to maximum... after you have installed 15 output pairs (enormous heatsink), increase drivers heatsink and drivers power capacity (use huge one)..tweak here and there..and you can make a short in the power amplifier output an then go out to work... 10 hours latter you will return home, then the transformer may be damaged, or a line fuse open... but the whole amplifier will be perfect....replace fuse, or replace transformer..and will have sound once again.... this is what i want.

regards,

Carlos

you are the destroyer... hahahaha

no doubt you can short speaker lines of DX.. or DHR .. I already replaced my transformer once.. hahahahaha Its a super reliable amplifier that i have never seen before.. but still you need a DC protection to protect speakers. don't you ??? 😕

I think Im the first one who made the DX and DHR in my country.. more people will make it later.. and it will spread all around the country one day.... I'm not a businessman,, just a person looking some money for foods and drinks hehehehe... I better make websites if I would do so... 😀
 
Suratot1, i have already selected a circuit to test..the Corporation crew man

are producing boards, we, brazilians from the Orkut audio designer group, will build and test..and them will be presented in the Dx threads.

Thank you by your help, but we already have selected the one we want..no chip at all, all discrete.

I have designed my one by myself...but alike all bad designers, mine resulted too much complicated, with a lot of parts..and this is the main clue of bad designers, the overcomplication when we can make it simple.

I have selected from a Book...people is preparing boards as i said...page 258, book Electricity and Electronics...by Randy B. Slone...also i found this one, modified by a Brazilian that seems good, or even better.

If I have to adjust a lot, and change a lot, that schematic mentioned, to force it to operate, to, or to work properly, then will be Naturalized Brazilian and incorporated in the Dx Corporation... and this depends how many parts will be changed/adjusted, and how hard work will be done to make it work perfectly....maybe nothing will be needed..then will not be a Dx design, nor a Dx style, Dx version or anything alike.... will be by appointment only.

This is not my priority, as fuses can do the job too...so, it seems to be a sophistication that we can live without it...it is in the third place in my list.

Schematic attached is not the final, nor parts nor circuit is final, it is just the start, the study, nothing was build and tested, the transistors will not be these ones too... this schematic is from Slone, it is wrong to write Dx there, was my friend Egbert did that...also we have Miguel that is preparing another diferent board.

Carlos

just a little question uncle carlos, Is it possible to design an amplifier that will kill the mid frequency but boost the bass and high frequency?
I know this is stupid but i just want to ask because im doing some experiment in amplifier and starting to study about designing.

Thanks
 
well masterinvi....

I have a same kind of question... is it possible to kill mid and highs without affecting to low frequencies in an amp excluding any passive or active filters ?? and can I try it with feedback capacitor ?? In which stage normally can we limit the bandwith of an amp (in DX, if and only u like/allow us to do experiments)??

As I know all good full range amps like DX are liner.. meaning all mid low and highs are balance. correct me if isn't true.

(please somebody tell me in which category i should ask these kind of questions in this forum, if this is off topic)

regards,
lycanlk
 
This is complicated and too much long to me to explain

also i do not know, exactly, if i can explain this.

Dx TriAmp thread shows passive filter in the power amplifier input, one for bass, other for mids and the third for treble...so, this may help.

Better to open a thread with this tittle, them all forum folks will help.

I am a little bit busy with my family those days, having visit in my home...so..i cannot enter this subject, will be too much off topic and will use several posts.

Please, open a thread and make these questions opened to whole forum.

regards,

Carlos
