I was starting to replace the paper capacitors in my Philco 46-1213 today. My first piece I think I made a mistake. I am as new to this as it comes so if this sounds stupid, please bear with me. I started by replacing the power cord, that went well. Next, I went to the closest capacitor (or what I thought was one at first glance). I took a photo of it then I sniped the leads off close to the cap. It was then I realized I may have made a mistake. What I thought was a capacitor with the wax melted out, now I am not sure what it is. It's hollow inside with a wire wrapped around the outside and covered in wax. I will attach photos below. Looking at the schematics, to me, it seems to be labeled L8? What did I cut out?
Solder it back in, I can't find it on the schematic but it's probably an rf choke. You should identify parts in the schematic before cutting. Locate the part in the schematic by finding out what the leads are connected to.
Yes, thanks. I kinda figured that out LOL. I thought I knew what it was until I cut it out. Coulda, woulda, shoulda but it's all too late for that. Live and learn I guess, it is not the end of the world. I don't think I can put it back in because I cut the leads close to the body to have plenty for the resoldering. I will try to put it back into place, it will either be ok or it won't. I guess lessons are not learned by not making mistakes.
It would not be the first time someone among us misidentified a part. I can remember working on a Sonora AC/DC set where I thought I found a faulty mica capacitor, the Ohm meter found "leakage", confused as to why the radio still did not work afterward a friend of mine figured out it was a resistor, a Micamold brand resistor. Micamold did not just manufacture molded mica capacitors, they did the same with paper, in similar cases, and wire wound resistors too. You may see the odd post about someone cursing at Micamold paper caps, it's not that they were poorer quality then any other paper cap, but they fail just like bumblebees/black beauties, and Sangamo "Little Chiefs" do, when they leak they get hot, and blow the end off or split.
I would guess that this choke/coil was wound with either 16 or 18 gauge wire, which is typically heavier then what a capacitor would use for lead wires. Though it doesn't help that they put this mess inside a waxed paper sleave, with no markings, though maybe that was their idea of tipping off that it wasn't a cap?

Thanks Arran,
I appreciate your input. I really felt stupid after I realized what I did at first, but now I am just chalking it up to a learning experience. I did not get to work on it yesterday, but I hope to make some time tonight and see if I can get it back into place. If it doesn't work out, I will cross that bridge then.
