regulator recap

[zamproject]

Hi all

I'm currently restoring large Studer 289

for the moment cleaning process are not finished, but in the mean time I slowly start the alu lithyc recaping which is not so huge as most of the desk are designed around tantal (up to 47u and some 100u)
i don't want to change alu over tantal, i like the sound of this desk!!! (i use a smaller one since 3 years)

But all card and modules have regulator or passive voltage divider splitting the -22v coming from main PSU/regulator rail and perform a symmetrical 0/-10/-20 rail
I'm tempted to change all tatal in this area for aluminum, my first consideration is security

What would you recommand? any advise welcome !


ex attached for line out card with simple voltage divider, c115 is tantal
