Default I am inspecting the Dx Blame ST green boards and i perceived

too much long copper tracks to the input....i am making a modification and the next pcboard layout will have this fixed.

I am uploading video right now to inform Juan Vargas and Zimmer what i want from their pcboard layout about this input.

You must remove all transistors and measure them out from the pcboard..use dessoldering tools or soldering pump...this is better and reduces the time wasted to search using multimeter when the transistors are assembled into the circuit..better to take them off and measure with calm.

Then replace the burned resistors, and make the modifications i have suggested in the last post.

The Dx Super A schematic is the Dx Blame ST schematic with some modifications in values...there are two new resistor in series with the first VAS colector and some other minor modifications...the circuit super A can be made separated and installed latter..the stand by bias is adjusted in 250 miliamperes each rail... please take a look at the Dx Super A thread and watch my videos please.

There you have the schematic and all you need.

regards,

Carlos

Dear Mergulhão,

Please let us know more details about DX Precision Amplifier. I had i look on its schematics in the Greg and become interested in details or even in a PCB set if avalable.

Regards From Brasil (with 'S' as we write it)

Default We do not have this amplifier anymore..no pcboards available

É velho pra burro, e já está superado por muitos outros modêlos.

It is very old and already overcome by other models.

In this moment, no high power model with pcboards available.... search the MKIII Hx thread to see if there's someone that wants to sell their boards, as some guys have not build...some guys have ordered pcboards but have never assembled.

Forget the Precision..... it lost the Precision as times goes passing by.

regards,

Carlos

Default Well Soheil95...moderators moved the supply to the supply forum

here you have the adress.... a pity, as usually people search for Dx things inside Dx amplifier threads.

Dx Supply, output adjustable, stabilized power supply

Layout is not ready yet...soon you gonna have it.

We have videos too... explaining how Super A operates and several video showing tests...please go to my channel and subscribe there, also click in fingers up because this helps to increase hits and popularity...when popularity is high, then huge number of folks goes there.... huge number of folks going there will increase the number of guys assembling my amplifiers...increasing the number of guys assembling my amplifier i will feel more and more happy...they are DIY, so, no money in this stuff... a clean thing, has not the dirty money inside the Corporation, the biggest Union of audiophiles of this planet...only the good ones have join us. All i have from this activity was a couple of free boards...the real payment is to see people happy and to share my amplifiers.

Also i am not paid to be in Youtube...i have not accepted their invitation to be paid ...because i want my freedom to post whatever i want, not to make merchandizing and propaganda, not to have advertisement flashing in my videos and being free to use the songs i want..if copyrighted or not....i want to continue to be free... imagine what i said to them where to put the money they offered me...yes!... was there!

Money shows the most evil part of humans, they become selfish and dangerous..dirty thing...needed for survival but something that shows all the bad things we have.....make people betray others, they go corrupted.

I do not use electronics to my survival, to pay my bills, it is not for living..it is for pleasure only...i have my Government job... for whole life, i made tests for that... first place competition with others 26 thousand guys.

Here you have some videos...there are more 500 videos there...several about Dx Super A, and Super A and that kind of stuff:

(1) How Dx Super A works, como funciona - YouTube

(2) Como funciona o Dx Super A, how it works - YouTube

Here you have my channel adress in the Youtube:
