My dear Juan..... my amplifiers are not magic..they are just good
and the main reason they are superior is the fact i do not use preamplifiers, tone controls or anything that can mess with the sonics in the input.
I would like to let people know that i do not suggest, nor support, or recommend the use of pre amplifiers/ processors/ tone controls/ boosters/ equalizers/ filters/ attenuators or anything that can mess with sonics....because this will make my amplifiers so bad as many others that uses this stuff.
Be happy with your tone control.... i am just informing you posted in a Dx thread..but this have not my support...you have the support to post here and anywhere, but this does not mean i am supporting the use of this stuff.
Protecting my quality is avoid people to introduce preamplifiers or any kind of modifications that can impair sonics.... as i said...this is the MAIN advantage i have when you compare my amplifier with others...they use to have a lot of stuff inside the audio chain to produce a mess in the sonics.
No, uncle charlie is not mad, or angry or upset...i am just standing by to protect the quality of mine units against misunderstanding...as you are always promoting my units, producing pcboards, movies and such kind of stuff, then people can understand (wrong way) that i am supporting tone controls... and this is something will tremble my bones even after my death...for sure i will shake inside the thumb if someone install a chip pre amplifier or tone control together a Dx amplifier.... a heresy, a sin or a curse on my soul.
I support you.... your friendship, your presence, your humor, your qualities as a good man...but not chip preamplifiers or tone controls.
Integrated circuits have a lot of parts inside..they use to be complete amplifiers with several distorting stages.... distances, or clearance in between parts, input and output, are too small..this forces to compensate and protect against electro magnetic coupling, oscilations and so on...the result is that chip amplifiers are really bad related audio reproduction and measurements.... i would like to ship them all to the hell with one way ticket.

Carlos

I completely agree that mucking about with the signal can ruin the performance of the system.
I completely disagree that adding all these external equipment and/or controls has anything to do with the performance of the power amplifier.
The performance of the power amplifier is just that. It reproduces the signal fed to it.
oh....! ok then I will fallow your knowledge guys so is not necessary at all, thank you guys for your feed back. I be honest I didn't think about that the distortion that this devices can produce I was just "curious" about it that is all, well I just going to concentrate on complete the other channel and take the guts out of a unit I have here to incorporate the Supercharged, one more thing I haven't listed to a stereo amplifier for a long time as today I'm using only one board Supercharged and it sounds really loud I can not imaging how loud and nice will sound with both channels working at the same time wow that would be awesome!

I will do something and will send you as soon as possible
Now a days i am a hell busy..... but i will manage a way to do.
For a while, dear Juan, go ahead with your project about tone control as this "switch" can be installed after on.
There's only one way to learn things...it is doing, and sensing into real life the results..we must listen and try all ideas....it is not enough for me to say it is no good...i must prove you and i gonna do it as soon as possible.
Listening with tone control and almost instantaneously switching to off tone control, them you will perceive differences after you manage how to twist your volume knob in order to compensate the gain differences you have while using the tone control.....because, we humans, perceive loudness as audio quality.... we perceive loudness as better...so...the factor "loudness" should be minimized in order to you to perceive the subtle difference in audio quality you gonna have with and without a tone control.
Will send you directly and personally , as i have not time (or will) to feed another thread with material.

Carlos

A Brazilian friend is playing with the Supercharger
He will make it work in class A.
Videos in Portuguese:
Regulagem da corrente de repouso DX-SC - YouTube
Teste do DX-SC com fonte de 43 volts 6A - YouTube
Save his channel adress if you want to see the operation in class A near future.

uhhaaaa class A on a Supercharger what?! 0.0 wow I got to check that! nice, hey here is my nice plain piece of aluminum lol isn't she pretty ? lol

Hey vargas! are those same boards? I ask this because I see they do not have "same" parts on the boards.
oh I'm sorry the the one with the main transistors is the Dx Blame ST the other board is the Dx Blame MKII Supercharged I'm just going to change some parts to make them both Supercharged, but my friend the Dx Blame ST sounds really good, but I decide it for more power output must of the music I listen is low frequencies bass so I need a bit more kick. see that is the beauty of this board design you have the option of building.

I was polishing the aluminum to see how it look I guess is ok also I sanded out before that so the hole left over metal pieces from the drill are gone so make it really flat surface maybe I just going to keep the heat sink opaque not to be shiny, but at least the surface is completely flat.

you should try with very fine metal sandpaper.I did the face of my amplifier and it does not look so bad, take a look:

looks good that way dear friend and not polish very good unit you got there lanchile "muito bom" very good. I forgot to mention why I did that, since I now that shine surface will transfer heat "dissipated" a lot faster when I was in the Army the gave me a class about heat dissipation and I saw a transistor on top of a really shine metal surface like a mirror I till today I never figure how a polished surface can transfer heat a lot faster "this is just me don't take me seriously"

Wow, very interesting about shiny surfaces transfer heat better! But, how often do you have to polish the heatsinks to keep them shiny? maybe I am wrong here, but I think the material of the heatsink is more important... I heard that copper transfers heat better than aluminum. I have never used copper as a heatsinks so I can not say if this is true. one question: is the "supercharged" amp that you are building a class A?
Vostro yes! you right I found that info online a few minutes ago, black matt works better here is the link if you are interesting: also here is my idea of a economical heat sink, on eBay you can buy pieces and put them together so a custom heat sink can be created, I might not need to much area dissipation but I guess is better to go safe.
