High Sym
Dear collegues
Each minute I like more the name of this amplifier in gestation (never mind the big word, I couldn't find another)...HIGH SYM.
What do guys think? Is it apropriate?
If not how about a little contest finding the name?
I still think it should be associated to the belloved Symasym
because it was born from it (even though the gestation period is not over yet).
Well, HIGH SYM could be HIGHSYM, couldn't it?
In my old country (Portugal) there is a tradition to eat 12 raisins
(dried grapes) at precisely 12 midnight, it brings good luck
they say.
Well, I'll do that for the HIGHSYM.....

MikeB, Thank you very much for taking time giving me a very thorough and informative answer. I did find the DOZ (with 4700 uF Cerafine at output) with a loose and somewhat weak bass. I overcame the looseness by using a 6n1p SRPP tube buffer between my CD source and the DOZ. The bass is nice and controlled now but still a bit weak. The DOZ's highs are pretty good with my highly tuned CD source with OPA627 running class A at its output stage, but its certainly not state of the art. I do not mind the weaker bass, but I will certainly go for clearer and better sounding highs. I will get a PCB board made as soon as I can down load a copy of Eagle to convert the BRD file to Gerber file and send it to a PCB maker. I made a couple of PCBs before, but rather not do it again. I understand that you most likely know all the information I wrote here, but I would like to post them here for the benefit of anybody less knowledgeable like me, but still desired a top notch system like your SYMASYM5. Wow!!! 60 watts in class A too!!!
From your admirer,
From your admirer,
Hi Tim, the 60watts are ClassB, with the default 55ma bias you only have 12milliwatts of ClassA power. It's a cold ClassAB... But don't be frightened, it does not sound like ClassB...
You can download .BRD files from my webpage. Be careful, i misused the upperlayer for the wire jumpers, i simply did not find out how to place wires in eagle...

What an ice idea....P.U.T.Z!....wonderfull idea!
P - Power
U- Unit
T= Transistors
Z= Zilions
Ahahaha!....great idea, wonderfull creativity, you are a Marketing gênius Mateus!
Tell us, have you studied that in University?...i am astonished with so sounding name....remember me sony....sounds very good!
That's perfect!...... you can spell easy...Putz!...a brand name that have a perfect sound....Putz power zilion!.
Symassym 6, Symassym 6.1, Symassym 6.1a, those are worst...yeah!
Also if you put those two points that change the pronunciation to a German will be perfect....in English may be Píutz!...in German Pootzt!
Wonderfull contribution, i think this year will made this thread reach half million hits!...but of course the name will contribute.
regards,
Carlos

I will inform our local University about that....very interesting....Zilion may be something alike Milion!, some German pronunciation...ahahahaha...great!...great!

I have already E mailed to Federal University about this name, the Mateus discovery.
Also i was thinking...the first letter, the "P" or the wonderfull name, PUTZ
The international language, English, has many nice words that can mach this "P";
Pace, pack, partner, piper, patriot, pavilion, peer, plausible, persevere, pet, phase, pioneer, pleasant,...and also Pavel that contributed with important efforts to Symassym amplifier
So, those letters can have enormous quantity of meanings, combined they will make sense someway...wonderfull!
Pavel, thank you, so i will keep 220uf, as no sonics problems using 220 or 10000uf.
Interesting, Mateus pronounciation in Portuguese is the same as Germans pronouce as Mathaus ...may be a German modified name.

Interesting, my unit produces 720 miliwatts under class A
I will check....all transistors conducting and 100 miliamps to output transistors...all them biased, no one cutted.
Maybe because my higher stand by bias.
Sounds great!

Hey Terry, where did you get those nice and big heat sinks? Did you fabricate them yourself? I am salivating.
tttking..salivating was adequated...well, i have questions to Michael, because he is
the designer, but, other competent guys, skilled people, that can help me related some doubts are welcome too.
The questions are inside 10 images i prepare, showing the circuit.
This way will be easier to me than to explain in English what i mean.

To North and South America....more three hours east cost will start to enter 2006.
happyness to everybody to this next year folks.
To Moderators, Audiofreak and all forum Management, my gratitude, here expressed, because of the patience demonstrated with me...an imperfect creature, trying to be more happy....hitting the head against the wall, crying and laughing and going ahead learning.
Moderators, almost all of them, demonstrated respect, patience, tollerance, capacity to forgive and strength not to envolve their own feelings, their own empathy, related people and other forum problems, ...for those, the almost 100 percent of them, those that demonstrated that capacity, please, accept my respects and my deep gratitude, as you let me, one more year around here, making my mistakes, and without beeing punished.

I bought them on ebay. They were actually twice that big. I cut them in half and used the other two pieces for the last KSA 50 that I built. I bolted them together to form a tunnel and used a fan.
I played the Symasym for over an hour and could put my thumb right on the outputs and they weren't even warm. I think I could get by with much less.
Blessings, Terry
Carlos, tomorrow i will take the time and aswer your questions. One answer is, full scale output into 4 ohms at 20khz was ~0.04%THD. This might be possible to be optimized, but hey, that's 500watts...
Terry, when you play loud into 4ohms, your devices might get very warm.
