Destroyer x Amplifier...Dx amp...my amplifier

[destroyer X]

And because of that, i have to tell you that.

"Dx Amplifier is the only amplifier that has audio power!"

Sorry, you have to understand portuguese... spanish people can understand too.

Well..... engaging brain you will perceive the meaning even not understanding words.

Lost in translation...

I guess my brain isn't fully engaged (no surprise there). I didn't understand it. I'll try again after more coffee.

foreigners are so better than my people, because school, because electronics, because science, because civilization, because first world, that i feel great to know i have just one advantage from you.....

At least there's something i know you all do not know.

ahahahaha!... to speak, write and understand Portuguese.

Not true Carlos. Brazil has you, which would raise the average country well into 1st world status.

But I could never live in Brazil. Too far to travel to get to hockey games.

hi destroyer X, very nice thread. i keen of your amp. which is the best amp of your? which circuit design should i follow?

i have some BD139 and 2sc2922...i want to use 4 pair of 2sc5200. can i use those transistor in this circuit? how about the sound quality and wats?

waiting for your advice.

thank you.

You need to be looking for quasi-complementary output topology if you only have 2sc5200 transistors. DX amps are emitter-follower, you need 2SA1943 transistors as well.

too much big and he is not from English speaking country.

Reason why "landed" in such a way....hehehe..no problems.

We can also prepare the amplifier to Quasi if he needs that.

hi,

i have 2sc5200 and 2sa1943. i want use 4 pcs of 2sc5200 and 4 pcs 2sa1943. which amp is the best of yours?

thank you.

Best power, better quality to use 4 pairs is Precision I

But this will be correct if you love power and love bass..if you do not need power and love treble, accepting lower power and only 1 par of output transistors to each channel, then go to HRII.

Here the options you have:

Dx Standard, 1 pair into output, 35 volts simetrical, 100 watts into 4 ohms, huge bass, fair treble

Dx HRII, 1 pair into output, 35 volts simetrical, 70 watts into 8 ohms, controled bass and excelent treble

Dx Precision I, 3 pairs into output, 64 volts simetrical, 270 watts into 4 ohms, controled and huge bass, special mid range reproduction, reasonable treble.

But if you wanna be very happy, and wants to drive me happy too, assemble all three amplifiers and publish many pictures of your construction here... also send me pictures of yourself, house, family, dog, tree, river fishes, plants, flowers, rivers,sky,forest,neighborhood,bicycle,automobile, town,ceramics, fly, ants, rocks and stones and all stuff...also can include a cat and a bird..and send all stuff to

panzertoo@yahoo.com

First i love electronics of audio
Second i love pictures
third i love pictures of audio electronics, hi resolution ones (bigger than 3 Megapixels with nice focus)

You need 6 pairs for PI... if you want reliable full power

You need only 2 pair for HRII... (I loves me some HRII)...
Oooh and they are getting prettier... the factory started doing the top and bottom masks I nagged about...

Board installed with 90% of bottom components on top for testing/confirmation oh and don't think you will get away with such a small heatsink on PI... I put a huge fan on that....
