Hi Everyone,

I am prepping for a Cornet 2 build and am considering using upgraded caps.  My planned upgrades are:

C200,C206, and C208 to Auricaps 1uF, 400V
C203 to Auricaps 0.1uf 400V
C202 to Sonicraft 47nf, 600V
C204 to Sonicraft 1nf, 600V

A couple question... Is it ok to use the 600V instead of the recommended 640V caps for C202 and C204?  Overall, is there any reason not to use this combination of Auricaps and Sonicraft caps --- would it be better to switch all the Auricaps to Sonicraft 1uf and .1uf, 600V caps, or is the 600V too high for these positions?

EDIT:  An additional question, I am trying to find a replacement for C100 and C101 (0.01uF, 2kV AC).  The replacement part suggested by Jim (digikey #495-1301) is no longer in stock.  A couple of possible replacements that have come up in previous posts are:

Would any/all of these work, or has anyone had success with these parts or with others?

Thanks for the help!

Yes, It's OK.

It's mainly the matter of taste. IMHO the combination could work well as is.

All the 3 caps will do almost equally. The first cap is not clearly defined which sinewave voltage it can systein for long time, but IMHO will be good too.

Great!  Thanks a lot for the help.
