Dx Blame ES .... based into the Blameless, i am trying a new amplifier

strong as iron.

YouTube - Dx Blame ES "O Amplificador de Ferro ll"

The model ES fan club does not accept any criticism related to the ES model...i do accept, and you see that i have created the ST to substitute the ES...but they have not accepted....well..... i am glad they like.

Is this one..all features are under test...this is the one i listen some hours each day.

The one that resulted the best..sinergy maybe..some different parts..some decisions taken in the absence of some parts that where substituted by others and sounded very good.

This is a good oportunity to you to experience the sonics.

Enjoy and be happy with the Blame ES.... one of the best audio amplifiers ever made.

Here you have the link to Rudi's group buy:

I have one channel sitting at 4.7 volts (positive rail, 4.8v on negative rail) across the 100R protection resistor (in place of fuse).

On the second channel, I can get 4.7 volts across the protection resistor (positive rail) but the negative rail differs by about +0.4V (e.g. 5.1 V). They track well, that is, if I adjust the potentiometer so that the voltage across the 100R drops to 4.7V (on the negative rail), the voltage across 100R (positive rail side) is 4.3V.

I didn't expect so large a difference. Does any one have any advice?

What is the desired voltage across the output emitter resistors (0.22R in my case)? That is, when fully powered without protection resistors.

Thanks much.

or huge difference in gain of transistors...but 10 percent or even 20 percent error is not too much for audio analogue electronics..... usually we have some errors.

Check your amplifier... measure your resistances..check them..... sometimes we read 39 and we install 390 in place.... this happens from time to time.

Inform your off set.... when normal it is smaller than 25 milivolts...... and understand that huge off set of 100 milivolts is even not important...because 100 milivolts represents one miliwatt...this is not important...do not move the speaker... anything to bother yourself about.

Power emitter resistances...from 1 to 5 milivolts is fine....bad when you have less than 100 microvolts...the idea is to have the output stage conducting, even in stand by mode...when conducting some voltage drop appear into the resistance extremes.

Be happy,

regards,

Hello Sir/Mr. Destroyer X,

I have been reading the threads of your DX BLAME MKII Supercharged and the DHR Turbo amplifiers. I can't see any latest threads for the DHR Turbo. I wanted to build both amplifiers. However, before I will start making the amplifiers, I want to know which one is better?

I like the DHR turbo as it can drive lower impedances as low as 2Ohms. Not to mention it is also very powerful. I have simulated the DH Turbo using Mulstisim 10 and it was great! I have noticed that it requires 1.8v to clip. Although, this is not the case in the real world . But the circuitry proves to be a wonderful piece to make.

Now, looking at your DX Blame MKII Supercharged (DX B.MKII.S.), makes me think twice. I haven't run the simulation on this amp at the moment but I have seen the test made on one of the videos posted. Will it be best to bridge the DX B.MKII.S. at +-55Vdc rails driving 4ohms speakers? I saw the video (Supercharged, 10khz square wave - 228 watts RMS at 3.5ohms. Bridging the amp driving the same impedance would be around 912Watts RMS.

Thank you so much for reading my post.

Cheers,

Is there a modification for the DX Blame series for it to drive 2 Ohms speakers?

[destroyer X]

to match your needs in sensitivity, ouput impedance, power levels and so on.

Be happy and enjoy,

Carlos
