Cary CAD-805C where is the 2uF coupling capacitor?


Hi all,
My question to anyone has done the coupling cap upgrade on these monos. I have schematic of this 805C and swapped out two .22uF but I could not find the 2uF that has .22uF bypassed (from 300b to power tube). I did take some pictures if someone can help on locating this cap - my contact email: thuan2000 at hotmail dot com
TIA

It appears that not all Cary 805C's used the 2uF coupling capacitors. I have two pairs and both have only 0,22uF coupling capacitors. This was confirmed to me by the Cary technical staff.
What would be the benefit/difference in using a 2uf vs 0.22uf value as a coupling cap?  Is a higher rating better?
