Here's a pic of the label on the capacitor can. This appears to be the factory original can:

   

There are 5 wires in total coming out of the can. Four of the 5 were clipped, only one of them, the white (or what appears to have once been white) wire is still connected to the chassis.

I tried connecting the 3 e-caps with their negatives all connected to chassis ground and positives to the connection points indicated on the schematic:

1.) positive of #46 between #11 & #12 on the candohm and to #9 the 110K ohm resistor
2.) positive of #47 to pin 3 of the 42 tube, to the output transformer, and to one side of the FC
3.) positive of #48 to the opposite side of the FC from #47, and to the filament of the 80 tube

After a full recap and out of tolerance resistor change, tracing through the schematic as I did to verify their locations (not just "shot gunning" it), all I get is a loud buzz that is not controllable with the volume. I even disconnected the high side of the volume pot so that just the wiper and grounded end are in circuit (in theory to isolate the output section from the RF) and I still get the buzz. Somehow I don't think all of the ground symbols are actual chassis ground. But which is which is the mystery
