Fried Op-amps..??

having issues trouble shooting these old amps.. I've tested all power transistors, everything seems ok in that department.

how do I know if I have fried opamps in my vintage Crown amps ?

I have a D75 and a D150a.. both have the ua739 ic opamps.. which I could blindly order some spares online.. but rather not if this isn't the problem.

the D75 only has one channel working
the D150a.. both channels not working
