Although there were some differences in the audio circuit the biggest difference is in the power supply. The "I" had an IC in the power supply regulator circuit that was prone to failure, the IC is available if you search but is expensive. The "II" had a completely discrete power supply.

An ex-GAS employee posted some of the schematics and alignment procedures on DIYAUDIO a while back.
