Ang ideal voltage source ay infinite impedance. Ang ideal current source ay zero impedance. Ang power supply at battery ay mga voltage source.
qguy you are the author of this thread you are making a war here!
another technique is to use several cans in parallel instead of just one, several small caps will have their esr's paralleled, better imho....
today's circuits like the gainclones have very high PSRR so that bypassing is not really needed.....circuit designs that are of high PSRR does not benefit from bypass...
War nah Were all friends here in pinoydvd, we have different views and beliefs and at the end of the day, each and everyones goal here is to help each other out...to find the ultimate bypass capacitor ..film, polypropolene or electrolytic , let the debate begin !!!
post not found daw....
let us not forget, the Aikido tube preamp also has higher PSRR when compared to a simple common cathode amp....same as with tube LTP's......

electronics is an exact science....people create religions.....i will post back whenever i see technical half-truths are posted..........nothing personal..........baka maniwala kasi ang mga newbies....... i have been personally attacked in this thread, pero hindi ko pinatulan......what matters to me is to get the facts straight.....when the truth is being attacked, you don't fight back by personally attacking the messenger....you fight back with the truth.....paniniwalaan ba nitin ito? susunugin ko na ba ang mga electronics books ko?
The problem with you is when you see things like this you say rubbish and you put links. As I said if you want to educate you should say thoughtful things as you are the more experienced. You can check the responses in diyaudio. This is what I am talking about.The reason I said infinite impedance is because across the voltage source itself there is no current. Furthermore I have thought that voltage sources consists of plates. And plates are not shorted but rather open.
Yes. That is correct. I admit it. Your response above benefits other people.I like that you go through posts line by line unlike some people here who like issuing blanket replies.
Great! Don't worry about it, it happens to all of us. Ganyan lang talaga si Tony, he's a swell guy naman.Let's all get along and give qguy a lot to think about capacitors.

where in my post did i mention the word "rubbish"? that is the problem with you, when pointing out your mistakes, instead of taking it positively, you go on personally attacking me....markrenz is way much better than you in this regard....your posting in diyaudio clearly shows your ignorance of the basic priciples.....high school physics pa lang tinuturo na yan......if you can admit that there, why can't you admit the same here?stop posting your technical mambo jambles, you sound more like a comedian than a techie........
that is also true and the sad part is when people throwing rubbish doesn't even know..... the good news is that there is the internet to verify such things...... but even then you really have to discern.....
High school physics. Patawa ka naman. Ikaw siguro iyung comedian. Inadmit ko na high school physics sa diyaudio??? ... ikaw na rin nagsabi ... you are putting words in my mouth ... bad yan ... since sa iyo galing ito very bad yan ...O sige na, tumahimik ka na. Dadami pa puting buhok mo. Tama ka. O ayan masaya ka na Professor. Damihan mo mga links mo para matuto ako. Wala kasi akong google eh.Pag-usapan na lang natin iyung mga bypass capacitors. Type ko iyung polypropelene kasi maganda tumunog.
Ang napapansin ko lang sa mga circuit design ay pag may dadaanan na mahabang wire/copper trace, saka naglalagay ng bypass cap malapit sa load (yung component na gagamit nung current) to prevent oscillations.Kung stable naman yung amplifier no need na ng maraming bypass caps. Kahit yung output lang ng linear power supply at power input ng amplifier (end to end ng power supply wires) ang idadagdag mong bypass cap ok na yun. Another gastos at effort lang kung lalagyan mo pa ng iba.Iilan lang sa mga tweaks ang may significant impact sa sound, at hindi eto yun hehehe...
Brod Rascal and Brod Tony T both of you are respectable Audio Geeks here, sometimes Electronics are like Religion, we have all with different interpretations somehow, we are all correct. qguy you are the author of this thread you are making a war here!Peace Brothers! Common! Stop this Technical Wars! FGS! qguy is just asking for a Bypass Caps hehehehehehehehe
Sometimes instead of bypass cap I just put high value resistor in parallel with e-caps. E-caps are really notorious as it takes very long time for them to discharge. Resistors are much faster than small value polyester, polypropelene, polystyrene and silver mica.
same principle..+ 1 to you bro. Also, using the right bypass cap matters a lot. One example is Wima MKP4 other bypass cap is also oil cap. I've been using it in poor PSU in DC Cap section. I am very happy with the results and others who heard and experienced it.
I know that the resistor would help discharge the caps after use. As for its use as a replacement for caps, wouldn't the dissipation ramp with voltage so minutely to be effective in damping ripple?
