Default ok

Having now read thousands of posts I think I can turn this thing on and try to get it adjusted.

Tell the DX Corp that there will be one more

DX amp, version HR version II version Nordic

in the field. I should be able to apply power next week.

Default Dx Corporation, the only one to offer you a collection of options


customized to your needs.... adaptable amplifiers to your supply voltage, able to use sub circuits to match your beliefs.

Wanna bootstrapp?.... we can give you one!

Wanna a CCS?.... we also can give you!

Wanna current sink?....no problems.

Do you want to switch from one to the other to listen the sonic differences?.... no problem, we can offer you that too.

Do you want to have your off set adjustable?.... we can give you such kind of thing...also using fixed resistance not to be adjustable too.

Want big condensers into the board?.... Nordic boards has room to that purpose.

Want nice rectangular board?.... dear Greg boards will make you happy.

Want many options to grounding.... we can wire Greg boards the way you want, to test, to listen and to learn things about grounding.

Be happy folks,

Carlos

Default Using a metal rule as rail and scratching using sharpened screw driver


or metal tip...then i will have a mark..... after that you broke the board alike people broke glasses into factories.

The rule enters as a reference..something to avoid to scratch curves..the sharpened point goes scratching following the rule edge...to obtain a straigth line.

We can use saw too...the small one to hobby works.

file and sandpapper are used too..all manual work

regards,

Carlos

Default I have made those ones today


I have only to install parts and adjust...it is almost made.

It gonna be used into a tinny aluminium enclosure..so...dissipation will be made using the cabinet.

Also will operate with 27 plus 27 volts...power is smaller.

It is the Dx Amplifier.... unmodified....it will look better after the aluminium be sanded and polished.... and having parts populating those boards.

Showing the scope....because it is pretty..and the boards are not..so...the image beauty will have some "balance"..some "compensation"

regards,

Carlos

I do etch manually like carlos do, hehehehe but i`m happy with it.

Default No dear Norazmi, it is the old and good board made by Greg Erskine


Here you have all you need about:


http://users.tpg.com.au/users/gerskine/dxamp/

Yes....the bias uses and external transistor fixed into the heatsink.

Mine, this one, use the layout you will find into Greg home pages dedicated to the Dx Corporation...the Dx Amplifiers.

thanks to Greg we have this helpfull tool to be use... a nice resource.

regards,

Carlos

Default You can see... some steel brush applied into the aluminium surface


a bad focus into the picture..another angle to make it big and tall..and them the amplifier becomes nicer.

regards,

Carlos
