[F-1540]

I am pretty pleased with the sensitivity of the F-1540 now.  Certainly some of my issue was noisy LED lighting, a noisy bench supply and the covers off the radio.  

I’m getting about 206 B+ voltage and it is looking pretty clean.  My schematic and service info I can find do not contain voltages.  I’m thinking this is about normal?  I was getting a decent signal on the bench at about -94 dBm. I’m thinking that is pretty good.  I hooked the radio to an end fed long wire and was happy.  I’m moving on to the cosmetics.   
The auto restoration suppliers had reproduction knobs and tuning bezel parts I needed.  The grill cloth had a hole poked in it so I tore into the speaker enclosure.  The speaker has about a one inch tear in the cone.  I suspected that as at higher volumes I could hear a bit of fuzz.
I’m thinking there may be a way to fix this with some kind of goo or patch.  Any thoughts?   It is an original field coil speaker and I would rather not replace it if I don’t need to.   
This has been a fun and interesting project but a little pricy as I was not in the hobby and most of my home electronics bench supplies  needed a refresh.  Maybe I need another project to justify the test equipment ?
