I am needing 2N5401 and 2N5551....other very interesting ones are

2SC4793 and 2SA1837....these are excelent....they are made of a non conductive material, so, prototype constructors does not even have to bother about insulators.

The plastic tool Rudi has to bend resistances matching circuit board's holes distance, is very usefull too.

Thank you dear Joseph.

regards,

Carlos

Is this a thermal circuit breaker/switch as these are? If so what would the opening temperature be?

Hello Niss_man,

I recommend a thermal switch rated at 70ºC, with normally open contacts. Get Jaycar CAT. NO. ST3833.

Don't worry about the effect of this switch on audio, since it's not in series with audio (it just activates the protection board relay, which should be of a high quality type).

Thanks Mitchel. Where does this thermal sw attach? The heat sink? Or does it just use the current in the wire to get hot ie. too much current=too much heat. If this were the case then it would be dependent on the size of wire used. If it is connected to the heat sink it would depend on the thermal conductivity of the heat sink?

Regards

Thermal switch should be mounted on the heatsink

BTW:
Mitchel
Do you have any plan to do pcb for dx blame with sanken transistors?

Like Dexter said, you should mount the switch on the heatsink. Screw it down, and don't forget to use a little bit of thermal compound in between the switch and the heatsink.

Now that you said it, I realized the MJL are smaller in width than the Sankens. I don't think that there's a good reason to use the Sankens: the MJL4281/4302 is a wonderfull pair, and as far as I'm concerned, you can get original pieces quite easily.

The Sankens are wider, and would make the PCB much larger ...

There is some escape, Niss_man...

If you manage to get heatsinks like these, you can mount each Sanken on a different floor (first transistor on the first floor, second on the second one, and so on).
Cheers,
Max.

Destroyer,
tell the whole story.
Your short form version gives the impression that Rudi has done something wrong.

The whole story will show that Rudi has done nothing wrong.
I believe it is another Brazilian that has proposed a corrupt arrangement and Rudi reported that to the Group buy and to you.

Do you want me to release some of the details, or will you come clean and admit what you have done?

Disregard my signature line.

I do not use to read him Workhorse

Let he say whatever he wants....from time to time i use to read, but was is disappointing so many times...that i give up about the man....has no more existence....evaporated!😉

I am in peace with my conscience...and this is what matters.

I am listening nice music dear Kanwar...wanna listen?

download them in the link suggested:

Ryan Adams Live at Das Haus on 2006-10-17 : Free Download & Streaming : Internet Archive

Try the big Flac files... use Videolan, a freeware player...then play them all loud....feel the contact with the divine!...feel those vibrations!

By the way.... Easy plateau...play it loud!

regards,

Carlos

I think Rudi deserves that the whole story be told.
As it stands, Destroyer gives the mistaken impression that Rudi has done something that needs to be "dealt with".

If Destroyer is not willing to tell, then I can give my one sided version.
I would rather that the "whole" version be told.

OK, tell us your one sided story and tell us where Carlos is at fault.

I am not going to rush into this.
I am not threatening Destroyer.
I can wait a while.
Let Destroyer consider his actions and let him decide what is best for the Forum and in particular in clearing Rudi's name.

I will wait until Destroyer tells me that he refuses to clear Rudi's name, or until I have no further patience.

Why Rudi himself not telling the truth? If he feels he is dragged into something bad?

Rudi has not resorted to telling untruths.
Rudi has been bullied into keeping quiet. I feel to reveal more at this stage may upset Rudi more than he already is.

He was a target. He rightly reported what was happening.
That is where Destroyer came in. Tell everyone what happened.

I am not a judge. I simply know some of the story and that little tells me that bad is being done, but not by Rudi.

The amplifier sounds delicious folks...despite these small problems

related the one makes the board and the one will not make the board..the amplifier itself is very good and it is much more important than the guys envolved, or connected to recent tragedies, and some not nice moments of our lifes.

Recently we had a scandall in a group buy.... i do not know about you..but this drives me sad...this depresses me... not nice things happening...i really do not appreciate all that dirty clothing being cleaned in public, looks not elegant...have some lack of class.

Well.... sounds matter... pleasure with good music and nice audio amplifier.

humans have their own troubles...and let them find their way to reach solution.

Enjoy the good amplifiers while humans are busy with secondary things... about the one will do this or that or those.

regards,

Carlos

Here you have some videos from a Brazilian...it is in portuguese

But it is interesting to see one amplifier build by a friend from the brazilian forum.

The amplifier appear to you to see.

enjoy:

YouTube - DX Blame ST

You have music ...something is loosing and vibrating in his camera..do not worry, the amplifier does not produce these noises..only pure and wonderfull sound.

enjoy and be happy.

regards,

Carlos
