Default Hello dear 4fun.... this subject is not for fun to me

The video will be deleted to give an end to controversy, theoretical discussions and excessive detail of things not so important.. what matters is the sound...the scope is going to be retired as it feeds such kind of things and attract some kind of people i would like to see distant from me.

I would like to ask the real friends, to avoid discuss and feed that subject...build the amplifier and then come to evaluate sonics.

regards,

Carlos

Sheesh guys give Carlos sone slack already!! Thats not instability of the amp! Amp instability looks like rings on the tops of the square or overall oscillation = fuzzy trace, not as bright dots in the leading slope.

Default It is interesting people dinamics.... despite such kind of things

are not nice to me...this increases a lot forum hit counter.

Interesting... people love some controversy...hehehehehe.

Social sciences may explain this... when thread is peacefull, going in perfect harmony, then hits are not so big..when there are some troubles..then people come to see.

The day i perceive the need to have more people reading, then i will invite a close friend to come to create troubles with me.

ahahahahahaha!...it works!

regards,

Carlos

Hi All

I have modified the PCB Track Toner schematic to have amplifier, power supply and speaker protect on the one A4 sheet. You will notice that some have backwards text on it. This is because some people may use photo-resist boards when etching. These people print to a piece of Transparency (see through) plastic so the writing helps the user to determine which is the correct way around. When the pcb is etched the writing should be readable.

Regards

I know It took me a long Time to do this but working with 1 hand does slow you down. But needless to say it,s been worth every burned finger i recieved. I,m so pleased with this amp that I can,t describe how I feel This is really a fanstaic amp.So please contiune to make more amp like this and I promise to buy everyone that you don,t sell..Also I would like to thank you and Mr.Rudi for turning me on to this project..and please forgive my terrible spelling..

Default Very helpfull dear Nissman.... the indications will help people to decide what side

to use....thank you... will ask Mitchel to do this way..as this helps.... he may use smaller letters as i do think it is more interesting this way.

Dear Evette.... i am very glad you could assemble... and with only one hand...very hard work this way.... i am also happy by your kind words...you are very welcome as you know... and thanks once again by the several packages of transistors you sent me.... so lovely the tiny ones you sent..the power ones, that i am felling pity to solder them...hehehehehehe.

He build a Brazilian boards we have sent him, as he was not lucky and post system have disappeared with German red boards he have ordered...Rudi returned the money to him to compensate his losses..then he have asked me Brazilian boards that arrived very fast in Canadá....it is the Dx Blame ST, a Brazilian version with boards inspired in Todd Johnson Layout.

The board image is attached for you to see...we have no more boards alike that..now we are producing the blue boards to Supercharged and other models.... was a kit including 7 boards, and you can see them visiting the Dx Blame ST thread...there you may have pictures, schematics and layouts.

Brazilian group buy has sold 200 boards of amplifiers, 200 board of protector boards, 200 boards of supply boards and 100 boards of surge protection.. also 80 power transformers and now they are finishing heatsink group buy...enclosure group buy was closed because price obtained was no good.

regards,

Carlos

Default Almost the same age...so you have learned a lot

Let Uncle Charlie in peace man!... amplifiers are sounding fine...we are joined together in perfect harmony playing our stuff..do not go creating suspections the amplifier is not perfect.

So many guys, around the world enjoying the amplifier..then you come to point errors...do you need to be famous?.... famous like that?.... pointing possible errors from others?... do you really need so much to be important this way?.... destroying the party?... creating bad mood?

You know, as you are old enougth, that amplifiers are never perfect technically... the back EMF is enougth to destroy everything...give me and give us a break man... a lot of posts already because your comment..just creating disconfort...engage your conscience and perceive why are you doing that..if you are really trying to help forum folks or helping your own bad feelings about me.

Let forum free..our personnal troubles must find a solution between me and you.

regards,

Carlos

Default About Brazilian forum and Brazilian boards

I was against to allow international community people to order boards from the Brazilian forum.... as people could enter there and order...knowing a little of portuguese alow everybody to enter there.

Why i did that way?

Because Brazilian forum have prepared very simple boards, the boards had awfull side cuts, you had to sand a lot not to cut your fingers... the surface was sanded to allow silk screen to be fixed.... the silks screen was bad, not well defined, not clear enougth...well.... board not high end, let's say this way..and very cheap....very, very cheap.

This created a problem, as Rudi was producing high end red boards,.... very good ones, perfect boards, golden plated islands, thicker copper layer, wonderfull colour and excelent board design by Metal... but this had a cost..boards are more expensive this way...and this was competition that should empty Rudi work if people could order from Brasil...i said not to that.

But.... Rudi decided to stop..he had troubles with German authorities connected to money transference from foreign countries that would create to him hard bureaucratic work..he gave up to keep a group buy..and several boards where spread around the world..very good job he did.

As Rudi decided to give up..then i have allowed brazilians to offer boards to outside brasil...but they could not collect orders written in this forum..should be made by a direct mail..could not even use PM..because not having a group buy opened in this forum, say www.diyaudio.com group buys section... then the one cannot operate here, on our forum.

One or two have received boards from Brasil, Evette, a personnal friend have asked, because his red boards was lost by post system.

Now we have a group buy.... a forum user have opened, the Brazilian Nabuco, called Mitchel here..now we can provide officially boards and we gonna do.

Brazilian cheap boards have finished..no one left...we gonna have new ones..the blue ones..high quality ones that matches the international price...we have searched for quality and price...not low price..but prices we see in the international communitty.... the price we have is the cost price..as group buy cannot have profit.

Mitchel is the one take care of board's stuff...i do not touch boards or money..he is the manager..i am in the Northeast and he is thousands kilometers south at Rio de Janeiro..boards will be ordered there, manufactured there or in São Paulo and will be send from Rio de Janeiro...he may send me one as demonstration.

regards,

Carlos

Carlos, do You what You want. If You want stay in mistakes , do it. Somebody must explore blind ways again. I have no personal troubles, , and I hope You too. Yes, amplifiers are never perfect, but we have to try make it so good as possible. Not adore faulty sound as "good sound".
