My Philco 37-116 Restore
#41

I managed to open up the Expander Unit and replace the grid cap wires. Tested the connections found they looked good and got it all back together. Pretty touchy work there. The springs in my unit were not touching the coils. 

I have started on the power supply section but have found my notes and pictures are lacking. Yeah I got sloppy here and I told myself be diligent. The part I am having trouble with is the Mag Tuning switch. I took it out to clean the contacts but messed up doing documentation. I failed to document 2 wires and now questioning the rest of it. I see the mag switch is two switches where when one section is on the other is off. I believe one section controls the flood lights and the other controls the mag tuning. From what I am noting when the flood lights are on the mag tuning side is open. Or the other way around. Is this correct? I look at the schematic and see three separate switches. One for mag tuning (#93), one for the floods (#94) and the other for pilot light (#135). There are only 4 contacts on that mag switch assembly. So I don't see where 135 comes from. I'm wondering if 135 is that contact behind the dial assembly? I'm thinking the switch contacts on the back of the mag switch are for the floods and the contacts around the switch are for the mag tuning. The picture below are my notes of the switch. RF9 and RF10 are the 6.3 volts going to the RF section. RF11 connects to a 99K resistor in the RF section. RF12 connects to another 99K resistor in the RF section. What I have labeled as Light Plug is the plug to the flood lights. As you can see I failed to document where the second wire of the light plug went. Tuner switch label is that switch behind the tuner assembly. I have included the section of the schematic I am referring to. So long story short I need some expert help here to determine where the wires go.
