Default We are working hard..nobody sleeping here.

Soon you gonna have the layout.

Increasing width of large current tracks.

I am posting an auxiliary image to novice folks, showing an example about how to wire your amplifier, take a look at fuses, each one of them should be calculated based into your parameters....inform them to me if you want some help.

regards,

Carlos

Default There's a long text explaining fratello

Take some time to read the thread please.

33 volts AC is what we want that gonna result in 46.5 Volts DC...you will adjust the supply output to 42 volts (maximum, do not increase because Dx Super A transistors will not hold more than that...read the entire thread)

Here you have files i have promised....assemble and enjoy..this supply is great..performance is awesome.

But do not assemble in advance to read the entire thread.

regards,

Carlos

Default Juan made another mistake.... pcboard is not good

So, please, do not assemble.

Juan will fix and will assemble at home in advance to send me files or publish files again.

I am sorry folks.

Default It is a mistake man!

All layouts published about Dx Supply are defective..do not trust in anyone of them...i cannot delete them because forum does not allow us to delete wrong images after some minutes posted.

The first one made by hand, by me, is working ... was build and was tested...but was considered weak...i have made upgrade..so...there's nothing for you to build, unless you do your own layout.

We will produce new images and i will inform you the one was tested..you gonna see picture showing the pcboard assembled to prove the layout is fine.

We are having a terrible sequence of mistakes... reason why i decide that:

" no one will publish anything without prior, in advance, construction to check"

regards,

Carlos

Default Here you have schematics

The one with green marks shows parts included or that had their value modified.

Default Old and new Dx Supply...the new one is bigger

In matter of fact i have increased a little (20%) the printed copy size because my capacitors are a little bit big in diameter.

The big supply will have three output pairs, and you see that we gonna have huge capacitance, including into the capacitance multiplier effect circuit.

The big one will be able to feed two channels of the Dx Super A

Volts into the series pass transistors will be 4 to 5 volts only, this way the dissipation will not be so huge as you may think.

I am just starting to build..pcboard corners cutted because needed to do this way....also the pcboard has side excess to be cutted out too...it will not be so big this way... at least 20 percent less and width will reduce a lot after trimming sides....video will explain you details soon.

I am assembling to test Zimmer layout.

regards,

Carlos

Default Preparing Dx Supply, Zimmer layout, part two

Here you have... some videos while i am doing.

Dx Supply - Zimmer layout - start produce & test part TWO - YouTube

This is the "poor men method".. something everyone can make...obviously the better idea is to order from manufacturer or buy the stuff already made...but there's no point on that because we are DIYers... and we are inside a forum called Do it Yourself.

There are other methods, photographic method and others...this is the most simple one, the most cheap one, the easiest way, but it is not the most rational method as this produces a lot of work and takes a lot of time
