The (high-cap.) unregulated PSU for chipamps

First come practical learning, later " Marconi's age " - but is sad, when guys think, that they get Marconi's knowledges by " gluing " of one kit , designed by other.

People who draw a line in the sand are always standing on one side or the other.

The questionable perspective then becomes not where but why.

You cannot build youself up, by tearing someone else down.

Don't we see this over and over again?

Well, i would say different.

there are many of those who dont consider how things would look like from the other side of the line, and there are many of those who themselves are so small, that they by them selves dont measure up, and so tear everyone else down so to make themselves high.

but I fail to se the context here really..
you were sugesting that i only se things from one perspective then?
In wich case you really should get to know me better before making making such asumptions. those who do, would not agree at all.

Please take no offense, but I believe if you judge the values of others, you must never stop judging your own. This may lead to comfort, but it hinders growth.

My post wasn't necessarily directed to you, but perhaps all the conflicting, and disparaging discourse of late. In the context of your statement, "there are limits to how much help people need, and should be given....this is not DIY", I say, you're free to feel it, but why bring this judgement here?

I built my house. Yet a truck delivered the concrete. I do not even understand "water of crystalization." So left to me, Keene's Cement would never have been invented.

Plywood, boards, windows, doors and shingles were also delivered. Trusses too. I used pneumatic nail guns...... and many machines to construct 39 raised-panel, white oak cabinet doors for my kitchen.

For a year, I worked alone.

Was it DIY?

I might say so, but the army of workers who provided the tools and materials might disagree. Even the banker that loaned me the finances. And what about the hearty young lad I recruited from a tavern one afternoon to help carry the trusses up the muddy drive?

There is comfort in believing, "Judge not, lest ye be judged." but even more comfort in helping others become all they are capable of becoming. So I say, if others draw a line in the sand, it is not my growth that suffers, I would rather build bridges than fences.

Season's Greetings, my friend.
Have a listen. (My X-mas card to all)

Guys, are you discussing the need of a PCB just to test a couple of big caps and snubbers?

[x. onasis]

Naw.... fences and bridges.

Welcome back Carlos.

Hmm.. it isn't every day something i read on a webboard makes me think and reflect on my own behavioure, but today is one of them.

Perhaps i should have paid better attension the other days as well when it takes such a "thourough" (lacking the english knowledge to put it in better terms here) reminder to get the thought process in order again.

I will keep it in mind, and try to take heed.

merry Xmas to you as well, friend, and all other here at diyaudio.

Carlos,

Do you really mean "adding" more capacitors or replacing the small cap with a larger one each time? Because really ADDING a capacitor would only DECREASE the inductance. Have you tried this??

Sebastian,

t = R*C would not give you a resonance frecuency if you don't include the inductance into the discussion. Actually, the total impedance would only decrease if the capacitance is increased and if the inductance is not changed.

So, incresing the number of caps (but not their individual values!!) would solve any problem related to high frequencies. Has someone tried this way??

BTW, Carlos, how do you compare the sound quality of 3875 and 4780? I am planning to built one of these GT's. Thanks,

Murat

carlos means exactly what is written in the scematic that you can find on page one.

and i must add: this snubber makes the GC a actual candidate for my main stereo rig, it is actally in place permanently now, bacause of the snubber!

Oh, how it makes the music sweet! warmth, openness and dynamic, even the treble decided to peek out

I can not stress enough what this does to the sound! i dont care why it does what it does, but it does what carlos said it would alright!

i'm simply stunned! lacking the words of wich to describe this! magic!!

thank you
