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

[destroyer X]

Attention, this last schematic posted was not very good..i had to tweak

a lot to put it to work, some resistances changed the value..not the values shown into the schematic...wait the 62 volts version or try the DHR Turbo to this purpose to use as a bass only amplifier, or a sub woofer amp.

regards,

Carlos

Making DX 62V is a super idea..

What a great idea uncle Carlos DHR Turbo is a super amp that I have tested too and a power hunger that will a very good solution for a sub-amp. but If you can make DX to handle more power (by making it 62v) that will be a great idea for my purpose. Im looking for a clear punch like DHR turbo but a little bit of high bass level. I wanna destroy my 200W woofer

Dear uncle Carlos, my filter has 2 stages.. first stage it cutoff all high frequencies above 200. 2nd stage it has a potentiometer to select the desired frequency between 40-160Hz with a notch filter.. after redesign the DX to 62v, please tell me if there any modifications of DX to tweak which to fit my requirements because your amps are good for all bass mid and trebles.

I'm waiting till you make 62v DX to complete my PCB

Thanks for the support

Cheers !

Thank you Lycanlk...here you have the schematic.

I will post, very soon, a description about current, voltage, power, off set, adjustments , transistor suggestions and more details.

Schematic has some transistors, just to point you some..others may fit and i will suggest others than the ones show into the schematic.

Details will be posted soon...including supply condensers...long text will come!

Also will point parts outside the Dx Amplifier board...this is a Dx amplifier with some resistances changed..to use the same published board you can see into the Greg Erskine pages.... this is a Dx Standard, the one is super reliable, hardly tested and many times guaranteed, with the down signature made by several folks that have built.

It is for Bass purposes only.... 1 hertz to 300 Hertz (-3dB), uses a passive filter into the input.... parts that are not into the Dx Amplifier schematic will be marked colour and different values will be marked too.

Made to BiAmp or TriAmp...with passive input filter or active input filter..sensitivity was adjusted to 1 Volt RMS of audio into the input.

More than 1.1 Kilowatt of power is possible, over 1 ohms load, having 62 volts supplies able to put out 15 amperes to each rail...using 20 pairs of output transistors.

regards,

Carlos

Details will published into Dx TriAmp thread... also the future versions

to midranges and high frequencies...they will be published into different threads.

in the future; Dx TriAmp midrange amplifier and Dx TriAmp high frequency amplifiers, will have threads containing schematic and all information needed to allow you to build tested amplifiers that will complete the TriAmp full range unit.

TriAmp is the way you have to be free of room acoustics, speaker enclosure balance, personal tastes and musical style.... you can adjust your way... three controls to each channel, plenty of buttons to the ones likes that (me!)

Carlos

Thank you uncle Carlos...

I had less time to involve with this.. also I had a problem with my internet connection.. it is fixed now.

Its another nice amp by the way. i'm waiting for more details..I cant understand some technical terms here but i will catch up those eventually.. your comments are most welcome when i'm wrong..

Carlos, are you planning to use MJE..and MJL.. instead of 2SC.. and 2SA... ?

 

[destroyer X]

No!... i am not planing to use other transistors than the ones i have

I have 2SC5200 and 2SA1943

Also i have Fairchild j4215 and j4315

Into simulators i use MJ transistors because my simulator had not other transistors than those ones.

But the standard power output transistors to my amplifiers are always 2SC5200 and 2SA1943

The standard driver transistor to high voltage units are 2SA1837 and 2SC4793

The standard driver transistor to low voltage units are BD139 and BD140

To the differential, BC556 to low voltage and 2N5401 to high voltage amplifiers.

those are guaranteed... to my own home things i use the ones are available, but i suggest to you to use, only those ones..because they are good and were hardly tested.


regards,

Carlos

 

[lycanlk]

Thanks dear Carlos..

I love 2SC5200 and 2SA1943 since those are highly available here and very cheep compared to MJ.... numbers. A good choice!

 

[destroyer X]

I am glad we both agreed about that dear lycanlk

Be happy with our good transistors...reliable, strong, safe and cheap.

Carlos

Dx Amplifier under construction... Dx TriAmp system, using Dx Amplifiers

All circuits are Dx Standard.

Under construction.... three supplies, three amplifiers, one for bass, other for midrange and the third one for treble... each one of them will have a volume control.

regards,

Carlos

 

[destroyer X]

Here you see the supply filters

It is under construction

Carlos

 

[destroyer X]

Dx TriAmp is made using Dx Standard, of course modified amplifier

Hello boys!... we have the Dx TriAmp thread here:

http://www.diyaudio.com/forums/solid-state/153060-dx-triamp-bass-unit.html

Dx Amplifier are used to the Triple amplification system.

Here you gonna see pictures dear Rudi (Germany) has sent me.

thanks Rudi.

Hmmm....

These Sankens rocks!

 

[destroyer X]

Yep..they are very good.

Carlos to have your head I work 24 hours a day

 

[destroyer X]

Thank you...but we are almost the same... depends on exercise

some skills only....there's no difference between humans.

Dx Amplifiers, all standard circuit with modifications

enjoy, one more nice product created because our marvellous forum.

Our forum friend Rudi is buiding a Dx amplifier.

He is from Germany (Deutschland) and he will travell to Munchen very soon... some pictures received from him will be posted down here.

The beer picture!...who will watch the beer glasses?

I think no one!

ahahahahahah!
