Prophet 5 dead voices

Hi to all,

I am a "lucky" owner of a Prophet 5 rev 3.3 with Usart. For a weeks I had problems with this synth, I buyed for 5 years ago and always any voices sounds louder than other, unless the synth is in Unison mode, when all voices are stacked obviously. Recently I recap all the tantalum caps with electrolitics and I changed the caps 6300uf and 2200 uf in the power supply with 10000uf and another 2200uf, I couldn't find 6800uf and in a forum I read that the 10000uf works too.

Now I have two voices missing.

When I check the power supply I have the following measures;

+15, ok
-15, ok
7.6 instead 5.6
+26 instead +22
-26 instead -22

Can these differents voltages kill the voices?
How can check what voices (what number) are dead?
What should I check?
Could be the 3280 related?

Thanks in advance.

Fernando.
