Rotel RX-803 - 2SA912 sub?

I'm trying to eliminate the last few gremlins in this Rotel. It crackles a bit and I've read that KSA912 gets noisy (and hot) so I'd like to replace Q605 and Q606 on the main amp board, which are listed as "main amp bias compensator". KSA1013 seems to be the go-to sub, but I don't have any on hand. I do have some KSA1142 on hand. Can anyone tell me if KSA1142 will work for this application?
