Subject: Which dual opamps does KSR replace for their restorations?

hi folks, im wondering if anyone (maybe the man himself?) has an idea of which dual opamps get replaced. i was looking thru the RL Music notes page, and noticed that the KSR full restorations include the CMOS logic chips, all voice card/output/psu caps, and "dual opamps".
im wondering which ones this is, and why? im not familiar with opamps being a time-sensitive part(i.e. preventative maintenance suggested), but there's alot i dont know about cs80's! as im already close to a full resto on mine, im considering doing the voice card caps, and maybe these opamps if they are suggested by sir kent of cs-shire or you other cs80 pros.
thanks guys!-rj
