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.

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.
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.
Rodman99999,

The values I have are as follows: output caps .22uF 450v, coupling caps 1uF 450v, and the wima caps 1uF 450v. These are the values from the TNT review but they are for the first version. I still believe nothing has changed for my version 2 other than the pwr supply. I understand the new v-cap is supposed to be very good. TNT used the Auri caps but my choices are many from the links given. You the man! BTW: I have a rca blackplate 6X4 doing the rectifier duties.
Rodman99999,

Ok here's what parts-express has in terms of prices: Hovland--.22uF 400v $10.38 1uf 4oov $19.42, Auri--.22uF 400v $13.71 1uF 4oov $15.20, Multicap ppmfx series-- .22uf 400v $4.26, 1uf 400v $8.22. Hovlands are are on sale and the Multicaps are the least expensive. The Vcap are really high-ouch- but the most popular. With my pre not being all that in circuit design(simple)I tend to lean toward the Multicap. Any thoughts? With the 1uF caps I need four the .22uf just two.
Rodman99999,

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.
Yep I saw that after I wrote to you. They do a great job in explaning things. Thanks again.
