It's a pot of tar and it's been added on as you can see from the electrical tape.  The blue wire goes to pin 2 of the output tube #42.  On the schematic it shows 2 caps which are described in the schematic parts list as "Condensers in Tone Control".  There is only one contact post on the tone control and after I get the tar out of it I'll take a closer look at that glob of solder which I'm wondering is a grounding point.  The other picture is a proposed sketch of how I planned to replace those two caps.  At this point I'll assume when the new pot was added it needed that "extra" cap I originally referenced and asked about.  If I follow the schematic and replace the correct value caps which I have, I would then remove that extra cap (30-4024-m).  If all this sounds kosher, is the proposed wiring diagram right?
Thanks,
