If you don't see it it may be inside the filter can.

Nope, cap#11 is a bakelite cap block. It was removed by the last guy and I've rewired it and other things the best I can by following the schematic. While it works great, as I look at the schematic, the ungrounded side of #11 goes up to the coupling capacitors (#8&#8, mounted across RF xformers 9&10) thru a lug on the transformer........But wait!!!!!......after careful examination of the schematic AND the photo of the underneath of the chassis, the last guy took the wire that should have gone to cap #11 and ran it to the 2nd grid of the 1st and 2nd RF tubes! (the shiny solder should have tipped me off). So I ran that wire to #11. Sadly, the radio works as great as it did before. I've now made the last wrong right, though.
