ja to uvek mesam - apsolutni offset je oo sto vidi zvucnjak , zar ne ?

relativni je prema gnd ?

ili obrnuto ?

mislim - znam koji je koji naravno , ali im mesam imena

ovde je prema gnd offset 24V ; par volti ni tamo ni ovamo

slazem se za RC vrednosti u servu - to ionako nije mnogo bitno u koncept semi , i ovde je Fc blizu 2 Hz , sto je naravno mnogo visoko

pitanje referenciranje kaskoda radi linearizacije ili radi totalnog ubijanja Millera. pitanje je sad

ce vidimo ......

[Sipi]

Apsolutni je onaj koji se meri u odnosu na apsolutnu referentnu tacku, dakle GND.
Relativan meris izmedju dve grane.
Servo ti gadja CCS koji napaja obe grane - kako ce da zna kojoj grani da doda ili oduzme? Svaka ce da vuce koliko ona 'oce od onoga sto CCS daje...

Ono sa kaskodom nije bitno, nece da znaci ni tamo ni 'vamo, nego tek 'nako...

Sad ne moras, ima ovde napisano, pa kad zaboravis...

[Zen Mod]

a kako da zapamtim gde je napisano ?




ko da ne znas s kim imas posla

[Sipi]

Ma ne moras ni to da pamtis, samo nazoves Miku pa ga pitas gde je search dugme....

Ruzo duso, kako se zove onaj lek...

I just saw your "twin" thread at big Diya.

It's gonna be fun to see if anybody there has the balls to actually build one.

Regarding Eagle......you know I can deal with it, so it has to be a walk in the park

Magura / whom soon will be served pancakes

I hope to. I don't know if I will spring the cash for a 'big choke', but will look into building the CCS'd version. Esp if it's got a free eagle file.
I don't know if my metal work will look like a Magura UFO, but maybe something that runs on plywood. Maybe even 'hardwood' plywood.
Otherwise, look forward to more details, and if it sounds better or worse than BJ2.

[Zen Mod]

you can count on it as open source project

better or worse than BJ2 - that will be matter of taste and room/speakers used

[Tea-Bag]

We will see..
I would run on Lowther PM5A on top of lowther open baffle. My listening area is part of main living area, 5m x 12m.
What is 'donut' size? I will take a look around for a choke. Else, have somebody wind one.

[Zen Mod]

I think that 500W (and bigger) toroid or EI isolation xformer will do the job perfectly

under condition that primary and secondary are identical , both Rdc and inductivity wise

in case that you want to wind your own , bifillar is way to go

I found two big round one's.

try to post that on big diya

No,they are not good, as they will saturate the core

Holy Smoke!
Now thats what i call round!

Well, if she goes on a diet for a year or two, she may even turn out to be a relatively good looking woman


How about making this amp usable on -12V and +24V ?

That would sort out a problem that sure will arise, as they don't like the power transformer any place near the inductors.

12 and 24V SMPS at 150W is quite cheap and common, and does not sport that issue.

few volts up and down - what's that between friends '

at least you know that's just matter of dissipation , nothing else

[Magura]

That's a fact, but as this could be a project for somebody with a less relaxed attitude towards that kind of stuff, I just wanted to point out that if the project was made for those voltages, there would be options.

Those whom stray away from the beaten path, most likely also have an idea about the consequences (counting out Helicopter-boy that is).

[Zen Mod]

...... couldn't agree more

[Tea-Bag]

Well, found two more round one's. I couldn't help myself.

Any more thoughts ZM on this science project? Some SiC Fet owners are getting fussy and uncreative that they don't have anything to build with them. : to_become_senile:
