Cap change advise for a Symphonies V2 preamp?

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.

At the bottom of this page( http://www.partsconnexion.com/t/catalog/CapacitorsFilm.html ) there are a variety of caps on which you can click. I talked to them the other day, and was told they would be carrying the Vcap CuTf, "soon". ( http://www.v-cap.com/copper-teflon-capacitors.php ) I've also used DynamiCap, Multicap and auriCAP(all matched to 1%, by Michael Percy) in the past with great results(depends on what you're replacing). Something simple to bring life(blacker background/cleaner highs) to your power amp: Change the rectifier section to fast/soft recovery diodes( http://www.partsconnexion.com/t/catalog/semiconductors.html ), unless it has a tube rectifier. Tweaking/modding can be VERY rewarding, if one is interested in achieving the closest approximation of live music, in the home.

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.

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.
