Default Oh... this is a very good idea!


Dx amplifier will sound better than the one you made before.

Guaranteed!!!

Carlos

Hi microp.

You wrote >>at mid it is something like raining. <<

??????? Thinking cap is on here.
Output induced oscillation ?

Have you kept all VAS output, all output stage and LS wires well away from input circuitry and the input differential transistors ?
What is your LS ? ( I ask in case the present construction cannot cope with either crossover or driver current demands.)

Cheers ......... Graham.

Default Very good Microp.... the schematic you can see in Greg website


Those Dx pages are updated.

Good to have young and handsome folks doing Dx....ahahahah

this promotes my amplifier.

"Now Dx amplifier is creating interest into young folks too!"

Also:

"Dx is beeing used together switching supplies into automobile"


Very good!

I will watch into the simulator some modifications to a higher voltage version to my friend.

Carlos

Sorry for black and white...

Finally had the faceblock machined flat today, so now I can progress again... will still have to have it glossed with a few coats of Glatex 8.

Everything is just standing like that... no screws, allthough the backplate's is done...

Default Thank you Nordic, as you have shown us your finished enclosure

Very good Nordic....Dx amplifier is playing very happy in South Africa.

Riche.... in some minutes i will check your modifications.

Good Microp, now Dx amplifier has constructors that have a face too....ahahahha.... i think the first one that had courage to post.

Courage is something apreciated by your friend Destroyer x.

Have a personal name too Microp...... apreciate also that you do not accept obstacles.....not having data you jump to make it by youself.

Congratulations Microp...you are a man!

regards,

Carlos

.................................................. .................................................. ...........

Graham

He had problems with an amplifier he constructed in early past.... in his post you can have the link to that schematic.

It was not a problem with Dx amplifier..... we have great midrange!

regards,

Carlos

.................................................. .................................................. .........

I feel happy when people go constructing my amplifier.... thank you folks.

Dx Corporation thank you all by the kind preference.

My happy picture during a very serious celebration...ahahahha

regards,

Carlos

Hello

Data sheet show static measurements on dummy load, but on a transient situation on a real loudspeaker the amp will reacted quite differently.
