apakah ini juga bisa di aply untuk misalnya 10 caps sekaligus ???

The cap-rack keeps the capacitors polarized while subjecting them to large charge-discharge cycles.

The AC output should be about 9 V, so the innards of a 12V - 14 V, 500 mA power supply would be ideal. Attach an AC cord to the input side of the transformer, being careful to tape or apply heatshrink over any exposed wire. > > If you scrounged the transformer from a DC power supply, chances are the bridge rectifier diodes are still attached.

The values were 10 µF / 50 V and 100 µF / 50V. Black Gates are the most notorious example I know of components that sound bad until a long break-in time has expired. > > In a email, Vincent Siu wrote to me: > The break-in time for the Black Gate capacitor is at least 200 hours and it does depend on how it is being broken-in, continuously or on/off (which takes much longer). The sound of the Black Gate caps before break-in is tight, dry, less dynamic and not musical. The sound will be excellent after broken-in with good dynamics, well controlled bass, neutral and musical sound with dead quiet background. > > The only thing I would add to that is my complete agreement. This is exactly what I found. It's been said dozens of times before, but I'll say it again: Don't judge them until you've had them in your system a couple of weeks ... or, less painful for you, run them on the cap-rack for a while! > > The cap-rack is for polarized capacitors. For non-polar elecrolytic or film capacitors the diode is emitted as these conponents can be connected diretly to the AC voltage. > > salam dari -B/P- kagem panjenengan > sent from my blackberry BOLD device 9000 > ------------------------------------ Yahoo!
