IG-5218 repair

I got my IG-5218 working again after replacing the pass transistor, Q4 and
Q5. I subbed a 2N2222A for Q4 and a 2N2907 for Q5, being what I had on hand.
The indexes and manual give different stories on the identification of Q5.
Manual says 2N2306, as does one index. Another index says 2N3906.

I couldn't get a good recalibration with my subs, the waveshapes look a
little bad and the sound in a speaker is not good. Any ideas for better
substitutions of the transistors?
