Notice that the LM329 should be mounted according to the thin outline meaning pin 2 ground!

Oh, yes. I looked at datasheet in it was wrong direction mounted.
Now it works like reference voltage.
But, now voltages are quite low (must of higher voltage toroid) and i have 2 of negative super-regulator and they have 1 volt difference of each other with the same input voltage. :|

Which reference voltage do they have? Voltages at pin 2 and 3 of the opamp?

Just wondering, why did you mount the LM329 not according to the outline?

Hi,
sorry for late reply. I went to holidays with my family for few days.

refence voltage of LM329: 6.8V?

Colour of SSR02 was red in description for 12V LM329. I have blue one. That confuses me :-P

At moment i dont have connected to amplifier, because of low voltages. I need to test with higher voltage transfromer.

regards,
Bostjan

The SSR01 and SSR02 are both exactly the same when it comes to placement. The LM329 should be between 6.6 and 7.25 volts and most devices are between 6.8-7.1 V.
