I have finally gotten most of the spring chores wrapped up and I am back on my Magnavox 175 project. I am a bit stuck on this multi section can. I have been able to identify on the can and confirm in the diagrams what capacitors I need. I am struggling to figure out the positive side of the new capacitors. The can is the brown square in the top"ish" right: I am not seeing any of the symbols marked on the underside. I did find a couple pictures of the symbols posted on the top side, I have not looked real close but I do not recall noticing any. Is there something I am missing? I have just spent about an hour starring at the diagrams for this amp and I am lost. Can someone help?
