The first photo shows what I believe to be the volume control on the schematic for this model. The problem that I am having is that a single connection with 3 components has become detached from the edge of the wafer assembly on that control. The thing that is baffling, is that the wafer does not appear to have any type of lead or electrical connection coming off of it where that connection would have been soldered to. Could it have been a common area for that connection with no electrical significance? Or is there  a small trace somewhere on that wafer that would served as the connection? I can't see it and it's not visible in the photos. The schematic does show what I believe to be the components that are connected to the volume control, which are the ones that make that single connection which appears to have broken away; the 25n cap, 15k resistor and .2M resistor. Does anyone have some experience with this this control and how this may work? The last volume control photo is the front side of the component.

Also, a second question the last photo shows a couple of blue capacitors. These are throughout the set. I'm in the process of replacing all the wax and paper caps and wanted to know if these should be replaced along with the others, or if they are reliable enough to leave in the radio? Thanks in advance for your assistance.

I'm restoring a German set that I have and found what I believe to be an electrolytic cap that needs replacing. From what I can tell, it's 20uf @ 35 / 40 V. However, what I can't tell, is what the positive and negative leads are. They are marked 1 & 2. See attached photo. I'm not familiar with this designation, can anyone help? It is sincerely appreciated.
