Cap change advise for a Symphonies V2 preamp?

BTW: If the values that you have are .22uF/200V and .47uF/400V, the other two caps should be 1uF/400V. Keep your eyes open for a NOS(50's), Mullard(Blackburn plant) 6X4 rectifier, for the preamp.

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.

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.

Of course simple(less in the signal path) is best, and caps are what nature(as in, "live music") seems to abhor the most. Ergo: my recommendations are always to go with the best/least obtrusive in any application. Of the ones you've mentioned, I'd personally go with the auriCAPs. Be certain to observe the proper orientation of the caps in your circuit:( http://www.audience-av.com/capacitors/a_applications.php ), keep your leads as short as possible, and find some WBT lead-free silver solder(very low melting point). Have fun!

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.
