Thinking back over the power supply on this set, I looked at the original wiring and it "looks" like the choke originally WAS between the two + terminals of the brown electrolytics. That's where it should have been. The way the wiring is stretched out across the chassis it's hard to see.

In the picture, the left hand choke wire goes to a terminal on the rear 6K7 and that same terminal has a wire that goes to 6 on the 6Q7, which is the + terminal of one of the brown 'lytics. The right hand choke wire used to go to 8 on the 25Z6 which also goes to the + terminal of the other brown 'lytic. That would put the choke from + to + which is how it should be. If that's what you see, remove the 1000 ohm resistor and put the right hand choke wire back on 8. That puts us back to the beginning! And the voltages should come up on the tubes. But do you still get buzz from the top cap of the 6Q7??
