Not sure I understand your question. Do you need more info than is found in the Service Manual here:

You have OEM Marantz OPTs?

I have the service manual my problem is that it does not write anywhere about the data of the output transformer, ie how much resistance or how much mHenry is each winding

The 8B output transfrormers were proprietary for this model only, the designer was rather secretive about certains aspects of it. One of the rewinder services that reverse engineered the transformers may have that information.
