Cap change advise for a Symphonies V2 preamp?


I have a V2 symphonies and wanted to change the coupling and output caps. TNT did post a review and changes but it was on the first version although the caps on mine are the same. This is the signal path part of the pre not for the pwr supply. I may decide to tackle that portion at another time. I have contacted YS audio maker of the these preamps but have not recieved any answers to date. Thanks and enjoy the music.

With a meter how would I check for proper orientation? On the caps I want to change there a white wire connected to one end and the other is a bare wire. Without a diagram to go by I need to know what to look for with a meter.
The site I posted(last) explains which lead(black) is connected to the outer foil of the(auriCAP) cap, which should be connected to the signal source in your case(coupling), for best noise rejection. Most of the better caps' leads are designated in some way to indicate proper orientation.
Yep I saw that after I wrote to you. They do a great job in explaning things. Thanks again.
