Cap change advise for a Symphonies V2 preamp?


Greetings,

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.

Hi South43- As with tube rolling; much depends on what flavor of sound you are after. If softer/warmer: you might try some paper in oil(like NOS Jensens), for more resolution/detail/transparency: Vcap's TfTf and somewhere closer to the middle: Vcap's OIMP. I'm going to try Vcap TfCu's in my Cary monoblocks, as soon as they release the .47uF 600v value. Of course, what you can use depends on the room you have in your chassis, and the values required.
Hey Rodman99999,

As always I thank you for your info. My problem is two of the three pairs have values but the output caps don't. TNT did mention the values so I may have to do some research. Perhaps changing one pair at a time? BTW lots of room but may have to use a hot glue gun or some blutak.
DON'T use a hot-melt gun! That kind of heat will cause damage to almost ANY of the higher-end caps. Rather, use double sided tape, or some of these sticky backed cable tie mounts( http://us.element-14.com/panduit/abmm-a-c/4-way-cable-tie-mount/dp/78F622?in_merch=Popular%20Products&in_merch=Popular%20Products&MER=PPSO_N_C_EverywhereElse_None ) and cable ties, pulled JUST tight enough to gently hold the cap(no crush). They should be available at any good electronics store. It's not surprising that the designer of the pre, does not want to communicate about you rethinking his design. Doing the caps that you do have values for should yield much. Go for it!
I thank you for the links and info. I'll do some shopping for the best price. I recently thought about selling but I'm a tweaker at heart Rodman99999 so stay tuned.
