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.
 
mark levinson ml2 on/off switch.

can anyone help please.ive recently purchased a pair of ml2 monoblocks,described as both working,after connecting them up,only one works.other amplifier tries to power up-then cuts out.it seem like its the on/off switch,as you can hear a quick burst of output from speaker and transformer kick in.anyone know where I might get a new on/off switch and if or this could be the problem.
 
I can make sure it is a circuit breaker made by Airpax (part no. 203-222-4984-1 ).
I ever replaced mine in 2007 , bought from onlinecomponents.com (cheapest at that time) .

I recommend to replace one pair together .

Hope this help

Cheers,
Riwin
