I opened up the Crosley from the Bandon Historical Museum that I'm working on. It has had a mouse in it at some point but I don't think it was there for very long. So far the best schematic I've been able to locate is: https://crosleyradios.com/battery-sets/TRIRDYN-1.pdf

There are not a lot of components to this set and the "wiring" is mostly metal rod. I did have two places where the soldering had failed. One was where the jack for the headphones makes a connection and was easily repaired. The second was the solder connection between the C- connector on the top side of the set and the metal rod "wire" under the set. It also had a very unusual extra wiring that you can see in the photo below. At first I thought it was simply a piece of wire that had gotten caught in the set but then as I pulled at it the two loops of small wire separated and were clearly soldered to the C- on the left and the A- on the right. That can't have been original I think. The schematic's pictorial drawing seems to show A- and C- connected with a dotted line. Perhaps that connected is made under certain operating conditions.
It would seem easier to just jumper them on the topside of the set where there are nice wire connectors. Any thoughts?

The component labeled #16 in the set is a parallel resistor and capacitor. I think the capacitor is OK at least as well as I can measure it but the resistor is open. Unfortunately the schematic does not give a value for the resistance. I would "guess" it has to be something like 2meg or so...any ideas on its true value?

At the moment I don't have any way to listen to this set since I have no headphones or a working speaker for it. I'll be rewinding the Thompson speaker coils but that will be awhile down the road. I hope to find a set of headphones on ebay that are working.
