You will see two wires soldered to the trap: one at the end which connects to the chassis and the other mid point tap which feeds the first sound IF amplifier control grid.

No I don't think the old T-103 is salvageable at this point but I'll keep it. The slugs are broken at the top where the tool tip goes to adjust it. Yes I can probably find substitute cores but for right now, I'm putting it aside.
I actually treated all three traps and their cores with the mineral spirits because I want to avoid any issues with them being stuck if they need adjustment.
Yes, the one being focused on is the T-103 trap and on install of the one Bob harvested from his chassis and sent to me, I soldered the tabs you described so we're good there.
I'll need to get back to you on this. I think I'm doing something wrong in the way I have step 6, the adjustment of T-103 configured. I'm not getting a DC read on the VTVM that's in the suggested voltage range. I'll be more specific on what's going on in a day or so.
