My SB Pro II has only one YAC512??

So is it normal?  The schematic for the FM module has two of them listed.  Will I need to butcher another sound card to get another one?

NM.  I noticed that only one YAC512 is needed.  The second one is only needed for additional outputs.  I found it about a minute after I posted the question.  Sorry for any inconvienece.

it is perfectly normal to find only one of each per card.
