Dx Super A

uncle carlos MJL4281A can replace the 2SC5200 and MJL4202A to 2SA1943
what are the components that need to be replaced
sorry my bad english language

Nothing needed to replace...just avoid 2 ohms loads

No replacement of parts, just put your transistors and be happy.

Here you have last revision.... showing brazilian flag colours

Brazilians are building ... we already have several builders working on it.

And Brazilian pcboard not ready yet..but people already etching and building.

Pride because of my people....because of that Brazilian flag colours surrounding the schematic.

Attention!

I do not have MJL4281A and MJL4302A models in my simulator, reason why you see other transistors...but the suggested ones, the standard ones are these models:

MJL4281A
MJL4302A

Miller capacitor was increased because of safety reasons (crazy transistors can be used and drive the amplifier into audio triggered oscilations ....models like 23193 and 23194 not suggested!

Please, do not use the transistor shown in the picture...was the only one that made the amplifier unstable.

If you like audio electronics and nice girls too....

Then watch Carnival from Brazil clicking in the link posted at the signature line.

Everyday, after 6PM (Brazilian time that is -3GMT) you can see live Carnival, HD, from main towns from Brasil.

Enjoy, it is for free....Youtube offering this to all of us.

Just that.

Brazilian pcboard layout being tested by Zimmer

Here you have a picture.

Amplifier will be submited to tests while watching the scope....and if approved will go to production.

Great Bahrain.... very good job!

I am assembling the Hell Cube.... a 400W subwoofer amplifier using Dx Super A inside and also the Dx Supply.🙂

Thank you both.....without any offence to you guys I can even share jpg. or pdf. drawings of SANKEN and TO-3 version for home etching if you agree specially to uncle Charlie.

This case was made for MAKO, but i have not sold the unit

reason why i had not the need to assemble inside the case and ship to the owner.

Was a design to be sold...including layout, schematic, gerbers and prototype tested inside a case....now, the design became something for future use in the Dx Corporation's future factory.

The case, as you can see in the Hell Cube video, is going to be used together the unit.

regards,

Carlos

Is ok dear Willy, you make the mod for Sanken transistors is yours to enjoy it that is the beauty of it, I'm happy that you customized to your needs and that is the goal of it, make it your own way, for you to use the part you wish to use and that will give also a peace of mind, and that is what we looking for, you did a remarkable work really nice work, you just give an example that with patience and some little thinking nice designs can evolve and keep getting better and better, thank you Willy 😀,I will continue given support to Dx Super A the best I can so Dx Super A it will be my special area to support, if I order another bunch will be more in quantities meaning lower cost, and I will announce if I decide to order more, not now ,but maybe in a couple of months, I'm honestly broke guys, dear Carlos alredy fix really minor changes on the board so on the new boards I will make those changes C13 150pF cap, also color too, on the factory where I order the boards they also have "red" so I will ask if you guys like it in "green" or "red" but red will be only at the bottom of the board, I already ask her and she didn't understand me so well jejejejeje so yeah the bottom only. like I always say that Dx Super A sound really good and still today one of the best solid state designs ever made from Carlos I have tested torture actually yesterday playing hard and is really stable, I haven't change the C13 to 150pF yet but soon I will for now I just use it at moderate volume I have a picture to proved it and I don't have a chassis yet and I don't care!!! is on my desktop nice and sexy!!!! look at me advanced terminal connection with air support low capacitance filtering E=Wire/air +air lol.


Ok now seriously, here is the layout with the changes to keep track of it. 😉

All right Bahrein, post your images please

What about black boards with white silk screen?.... or white boards with black silk screen.

..anyway I have read about the DX PSU is it also for share..I could not find any pdf file for DIY in the thread...🙁


TY!
