    Trying to locate and list all caps I will replace.  I believe I have located all paper, wax and electrolytic but I have one that I believe is not on the schematic and it's a 10 mfd @ 450 V.  The negative lands on the ground of the Bakelite block while the positive goes to a terminal strip on the same junction as a resistor going to pin 3 of #78 and the second IF assembly.  My original thought was to replace the others and see how it plays with and without the 10mfd.  I'm just curious if I'm missing something obvious that a more experienced  person would see.
Thanks, Mark

Don't worry abt it, it's in parallel w/#25. It's an old repair. Just pitch it and keep going.

figure out what all those squiggly meant.

Now I think I've got!
