ML2 audio card adjustments

Does anyone know where are the measuring test points and adjustment value targets on the 4 trim pots (see below) on the audio card of the Mark Levinson ML 2 amp.

1. IM Balance
2. Invert Balance
3. Card Current
4. DCO - this one is easy to get minimize DC offset on the speaker terminals.

Look forward to getting valuable comments from anyone on this threat:):)

The 4th is DCO which is easy to adjust to minimize DC offset at the binding post.

Appreciate any valuable comments from anyone.
