There are a few differences between the -01 (Asteroids, LL, Football) and the -03 (Asteroids Deluxe) ARs...
It's not just a matter of a different cap value (and the speaker connector).
The -01 has an "audio disable" capability (pin 7 on J7), and associated components (Q4, Q6 etc). The -03 lacks this functionality. I know Asteroids doesn't use the audio disable feature; I'm not sure about LL and Football.
The input circuits are a little different on the -03, with the addition of R15/R16 between the signal and GND (not present on the -01). Also, the value of C6/C15 is 10*uF on the -01, and 0.22uF on the -03. I suppose this will affect the frequency response somehow...
FWIW, the feedback loop (and thus gain) appears to be the same on both.
And, as you've noted, the output coupling caps are different values.
