I just bought a pair of used amp packs for my passive SCM 50.

They are MK1 (please correct me if I'm wrong) and came from SCM100A (serial 24xx).
I am going to recap the amp and would like to calibrate them for my SCM 50, if there are anything to change between SCM50 and SCM100.
Anyway I would like to check the settings before connecting my woofers.

Can anybody help me with the right procedure ?

Compared to newer revisions of the amp pack, the PCB seems to lack quite a few things.
One thing I noticed is that there are only trim resistors for H.F. level + phase and M.F level + phase, compared to a L.F. level on newer revisions.

Thanks
