Is the sound section of the ARII and ARIII the same? I ask as I have a couple of ARII rebuild kits, but my Paperboy has an ARIII and some sound issues (background interference mostly) and I wanted to re-cap it.

If the audio section is the same... I'm golden. If not... well...
 
Afraid not. They're quite different.

Different amplifier IC (TDA2002 vs TDA2030), different amplifier power (10.3V vs 22V), different output coupling caps (1000µF vs 3300µF). The input coupling caps look to be the same, though (both 0.22µF)... Mostly different, though. (Not sure what's in an ARII "rebuild kit")
