EAC detect a Track 02 pregap of 0 seconds:

On that picture I go back 150 sectors:

My drive is Slimtype - DVD A DS8A3S (Correction Offset is +6)

What value 'Combined Offset' I must use in EAC?

EAC has a bug when there is 1 data track and 1 audio track.

So, I must set combined value +8 (+2 and +6) in EAC? Or maybe +7 (+1 and +6)? Or what?

I would say +8 for EAC in this case if your scrambled sector length is 0x20 (=32/4=8). This assumes that you have a 2:00 pregap (i have seen 3:00 and 4:00 and others on PSX disks too).

Hmmm... Ok. I'll dump Track 2 with +8 (+2 and +6), but dump must be added with Yellow Light status.

There's no point in adding dumps with yellow status.. You can try extracting with IsoBuster extract from-to and then correcting the offset with hex editor.. see if it matches EAC dump with dummy pregap added.
