np, thanks for presenting this amp, when I finish with the other channel I'm gonna use as much as original parts as I can.
I was seeing seeing a lot of happy people with this amp so I have to try it too.
I'm planing to make it on etched pc boards on the future.
That was exactly the main objective, the target when i have published my first
amplifier... to allow people to have fun building nice sonic devices...i feel happy as i could provide you something for your and enjoyment.
This is my main pleasure in life... if we cannot make other guys happy...we do not deserve happyness too.
Inside a community, if we cannot give something for our friends..well...we serve for nothing.... i am driven by this belief that we can be happy doing some for others .... it is absolutelly awsome when we feel that we could make someone happy... the ones did that knows what i am talking about.
The real designer of these things is Douglas Self... i do think he was blessed, inspired by the most high when made this design, searching for low distortion... he made, in the early moment, a hell stérile sonics..but tweaked we could find (and he said was a basic, a starting design only, to remove reasons people can present to Blame an amplifier... reasons for blaming was reduced together harmonic distortion and harmonic distribution) ... he found the source of good sound..the magic, the real sweeteness in sonics.... each morning i turn my units on to play music i have new pleasure and new emotions... once and once again... each day one more pleasant day... discovering details in old musics and the absolute lower distortion that allow you to crank volume up without fear to mess with everything.... the higher the volume, the better to sound is...lovely...just lovely.
In my imagination, as i did not have tested new designs from him (only three) , i have the belief he have not made anything better since that inspired moment..because..there's anything above the top, maximum, absolute peak performance...the top high end.... cannot go above the maximum...as it is something absolute..there's anything bigger than infinite and better than the top performance.... there's something impossible to make something better than the best.
Man.... Douglas was visited by the most high and inspired when he made Blameless.... kicked all others, easy, laughing and rolling over the floor ... eating everybody and everything in the breakfast..absolute no chance for others.... all people can make is to copy him and try to produce some magic in sonics tuning.. stuborn ones will be always the second, third, fourth or fifth place.
Based and supported in more than 50 years building i can say you have made the best.... in the future you will perceive that trying other circuits... increase speaker's quality, home acoustics, audio source quality, search for better recordings..but do not waste your time building more amplifiers...you have the best...try only higher power versions or lower power versions of Blameless or "tweaked clones" to match you home size, speaker power and personnal taste and needs.... you have already the best in amplifiers.
Higher power clones are beeing produced, the MKIII and soon the MAKO, despite the last one will be very strong in power and in bass...while the MKIII is having a little bit different sonic signature..standing in voices.
There are other options, almost alike... almost the same...with tiny differences in quality and sonic signature..but this is all..... variations around the same theme.
Visit Brasil..we have music in our vains.... as a part of our souls..... but be aware, you should never return for your country.... just do not say i have not warned you about that....here you have the Paradise.
regards,
Carlos

I will use this heatsink to the MKIII ... but it seems not very good
a set of 2 of these ones will be good for 600 watts only...the metal alloy is not good to heatsinking as i could check:
YouTube - Huge heatsing, strong metal, but heatsinking is not very good

Ahahahahaha!...trhere are many modern cooling methods you should learn Ostry
Try to learn some options my dear:

Those heatsinks are Lightweights considering their surface area.
The fins have a thin aspect ration.
The backplate has a thin aspect ratio.
600W maximum power capable output devices will run hot, maybe too hot.

600W maximum power capable output devices will run hot, maybe too hot.
From their shape (see the mounting places at the end of the most external fins) they might have beeen intended for forced ventilation (FAN) cooling.
Before somebody shoot them with a shotgun, of course.
generally blown sinks have very closely spaced fins. The power of the fan motor makes the forced air turbulent and much better at removing heat from the aluminium.
A Natural Draught sink has wider spacing to allow the hot air chimney effect to work reasonably with minimal friction losses, since there is almost no "power" to drive the air up and therefore no turbulence.

Yeah...it may be too hot...then i will cool it down.
I have not a bigger one..this ones, these heatsinks, are for my prototype testing only.... sadly i have not a bigger heatsink....i would need 4 times this size to keep this thing working cold the way i like...not going above 45 degrees celsius.
I gonna try a couple of fan blowing air and will make my tests at 500 watts RMS for a short time to evaluate the bias reduction (thermal sensor, diodes in series attached to the heatsink)... and will make further testings using music..then i will have average power and these heatsinks will manage the heat.
My town temperature have dropped a lot... now 25 degrees celsius..this will help too.
For future builders, as this amplifier is still in the prototype testing stages, i will suggest a much bigger heatsink.

I am happy to inform folks that one of the best Youtube show man will
Build the Dx Blame ST.... and this is very good ... as he has half million hits and as a result i will have a couple of hundred fellows building my amplifier..... and i have less than 170 thousand hits only.
The guy is very interesting.... i can remember myself watching him ... he also love the Akai 4000DS MKII that was my first open reel tape recorder (cost was almost the same price i could buy an old beetle from Volkswagen...one year used beetle), he loves electronics and is always ready to try new ideas... see his transistor insulators, the guy is creative, that thing will not work unless he use some thermal grease into both sides of that piece of paper... also the plastic washers to the screws will melt...but he will fast discover that..and this is the best way to learn things.... some creative thinking.. some try and error and to put the hands on work.
I have asked him.... please .... to build my amplifier ... because Clem is good.... actually he is very good.... alike me he used to be at home doing things even when the sun was shining outside...the same crazy guy.... but he will be excelent in matter of years, as he is very clever, has deep passion by electronics and he is also very young.
Watch his video folks:
YouTube - CDC ElEcTroNic Work Shop - Beginning of a DX Amplifier.avi
Yep..heatsink no good... there are several errors..but he will fast realise where are these errors.

Hi Destroyer.
I do not concern myself with testing heatsinks to destruction.
I want to test my electronics do not self destruct.
A small heatsink on a large amplifier is not a problem in test situation.
I usually set up the test arrangement such that a -20dB ref maximum power is passed through. flick switch to -0dB position and check the scope for no clipping and immediately flick back to -20dB position. The heatsink hardly changes temperature that this 1second test takes. you can repeatedly fine adjust the input signal level to find the highest unclipped voltage at the output. a dozen 1 second tests over a 1minute period causes no heating problems.
Now add on your rms scaled voltage meter.
flick switch to -0dB. Allow just enough time for the voltmeter indication to "settle". This can take from 1 to 2 seconds. flick back to -20dB.
The electronics have been tested for this particular combination of output voltage and load. The whole amplifier has hardly changed temp from it's quiescent condition.

Cool dude is building the Dx Blame ST
And facing the real world mistakes that happens when we build amplifiers...this happens a lot....mistales is what humans does all time long...or more than half the time, ... being optimistic.
Building amplifiers drive us humble, because we see how many failures we do...and these things happens all time long ... the ones build, learn very fast that we are not "that" special.
We can check once, twice or many times and we still watch without see mistakes...well...at least this happens with me, almost daily:

Hi,
i have build Supercharged version and tested it with B&W, Tannoy, and now recently tested with old yamaha ns-10. It sounded superb. i realy liked it.
Thank u sir carlos for helping me too.

Well I've been busy but here it is, XD the second channel and sounding awesome.
Voltage used 32-0-32
Voltage used 32-0-32
I have made modifications in my own amplifier, the one i use
together my computer.... i have reduced power introducing a small external step down voltage regulator using transistor and zener, a series pass circuit, the same used in the HRII several years ago.
The idea is to match my amplifier with mine beloved Philips speakers (picture attached) removed from a junk system made in Nederland... speakers are low power, so i am reducing power not only to match the speakers but also because i have removed the main heatsinks previously used in mine Blame, to use it into another amplifier...mine own amplifier is having small heatsinks now a days... it cannot dissipate too much power.
I have called this one Dx Blame ST - Home edition.... because it is really my home edition, and i am trying the colector resistance in the first VAS...i want to listen to it and confirm in the long run things i have already perceived about it.... i do think it will be removed near future.
Here is a video about it:

I have finished my home edition.... and i have removed Q6 colector resistor
Also removed the input condenser because blurred the bass.... 100pf capacitor was used.... goto the video you have in the previous post, then you will understand what i am talking about.
Here is video... step down rail regulator installed:

It is always nice to tweak, to upgrade, to update and to enjoy good sonics
Really guys... Doctor Self made a very huge contribution to our people creating the Blameless.....nice amplifier...always a pleasure to listen to it.
Search a Blameless style design, or even the original and build it guys... there's anything better:
